Ratings for the show became the highest of all three shows that aired in SBS's new ""Good Sunday"" lineup as the show is educational and entertaining to watch. It was also the first and currently the only variety show that included every member of Super Junior as regulars. Each episode has a main topic to explore regarding the human body. In the first episode, which involved the tongue and"
"Sartorius muscle The sartorius muscle () is the longest muscle in the human body. It is a long, thin, superficial muscle that runs down the length of the thigh in the anterior compartment. The sartorius muscle originates from the anterior superior iliac spine and part of the notch between the anterior superior iliac spine and anterior inferior iliac spine. It runs obliquely across the upper and anterior part of the thigh in an inferomedial direction. It passes behind the medial condyle of the femur to end in a tendon. This tendon curves anteriorly to join the tendons of the gracilis"
"Masseter muscle In human anatomy, the masseter is one of the muscles of mastication. Found only in mammals, it is particularly powerful in herbivores to facilitate chewing of plant matter. The most obvious muscle of mastication is the masseter muscle, since it is the most superficial and one of the strongest. The masseter is a thick, somewhat quadrilateral muscle, consisting of two heads, superficial and deep. The fibers of the two heads are continuous at their insertion. The superficial head, the larger, arises by a thick, tendinous aponeurosis from the temporal process of zygomatic bone, and from the anterior two-thirds"
"muscles, tendons, and ligaments. The spine of a horse's back is supported by muscles, three ligaments, and abdominal muscles. The ""Spinalis Dorsi"" originates on the fourth cervical vertebra and inserts beneath the thoracic section of the ""Trapezius."" The ""Longissimus dorsi"" originates from the last four cervical vertebrae, and courses along the spine, inserting eventually into the ilium and sacrum. This muscle contracts the spine and also raises and supports the head and neck, and is the main muscle used for rearing, kicking, jumping, and turning. It is the longest and strongest muscle in the body, and is the muscle the"

Another is that the muscle closely resembles a tailor's ribbon. Additionally, antique sewing machines required continuous cross body pedaling. This combination of lateral rotation and flexion of the hip and flexion of the knee gave tailors particularly enlarged sartorius muscles. The sartorius is also called the honeymoon muscle. Sartorius muscle The sartorius muscle () is the longest muscle in the human body. It is a long, thin, superficial muscle that runs down the length of"
"Latissimus dorsi muscle The latissimus dorsi () is a large, flat muscle on the back that stretches to the sides, behind the arm, and is partly covered by the trapezius on the back near the midline. The word latissimus dorsi (plural: ""latissimi dorsi"") comes from Latin and means ""broadest [muscle] of the back"", from ""latissimus"" ()' and ""dorsum"" (). The pair of muscles are commonly known as ""lats"", especially among bodybuilders. The latissimus dorsi is the largest muscle in the upper body. The latissimus dorsi is responsible for extension, adduction, transverse extension also known as horizontal abduction, flexion from an"

"Femur The femur (, pl. ""femurs"" or ""femora"" ) or thigh bone, is the proximal bone of the hindlimb in tetrapod vertebrates. The head of the femur articulates with the acetabulum in the pelvic bone forming the hip joint, while the distal part of the femur articulates with the tibia and kneecap forming the knee joint. By most measures the femur is the strongest bone in the body. The femur is also the longest bone in the human body. The femur is the only bone in the upper leg. The two femurs converge medially toward the knees, where they articulate"
"bone forming the hip joint, while the distal part of the femur articulates with the tibia and kneecap forming the knee. By most measures the femur is the strongest bone in the body. The femur is also the longest bone in the body. The femur is categorised as a long bone and comprises a diaphysis, the shaft (or body) and two epiphysis or extremities that articulate with adjacent bones in the hip and knee. In cross-section, the thigh is divided up into three separate compartments, divided by fascia, each containing muscles. These compartments use the femur as an axis, and"
"strength can indicate underlying pathology, with the chart at right used as a guide. Since three factors affect muscular strength simultaneously and muscles never work individually, it is misleading to compare strength in individual muscles, and state that one is the ""strongest"". But below are several muscles whose strength is noteworthy for different reasons. Exercise is often recommended as a means of improving motor skills, fitness, muscle and bone strength, and joint function. Exercise has several effects upon muscles, connective tissue, bone, and the nerves that stimulate the muscles. One such effect is muscle hypertrophy, an increase in size. This"
"are separated by tough connective tissue membranes (or septa). Each of these compartments has its own blood and nerve supply, and contains a different group of muscles. Anterior compartment muscles of the thigh include sartorius, and the four muscles that comprise the quadriceps muscles- rectus femoris, vastus medialis, vastus intermedius and vastus lateralis. Posterior compartment muscles of the thigh are the hamstring muscles, which include semimembranosus, semitendinosus, and biceps femoris. Medial compartment muscles are pectineus,adductor magnus, adductor longus and adductor brevis, and also gracilis. Because the major muscles of the thigh are the largest muscles of the body, resistance exercises"
"syndesmosis with very little movement. The tibia is named for the flute ""tibia"". It is the second largest bone in the human body next to the femur. The leg bones are the strongest long bones as they support the rest of the body. In human anatomy, the tibia is the second largest bone next to the femur. As in other vertebrates the tibia is one of two bones in the lower leg, the other being the fibula, and is a component of the knee and ankle joints. The leg bones (femur, tibia and fibula) are the strongest long bones as"
"musculature is found in(almost) all organ system such as hollow organs (e.g. stomach, bladder), in tubular structures (e.g. vessels, bile ducts), in sphincters, in the uterus, in the eye etc. In addition it plays an important role in the ducts of exocrine glands. It fulfills various tasks such as sealing orifices (e.g. pylorus, uterine os) or the transport of the chyme through wavelike contractions of the intestinal tube. On the one hand smooth muscle cells contract slower than skeletal muscle cells, on the other hand they are stronger, more sustained and require less energy. by Aatir Ejaz Cardiac muscle is"
"axis is the largest, and is chiefly muscular in structure. The semispinalis thoracis (or ""semispinalis dorsi"") muscle consists of thin, narrow, fleshy fasciculi, interposed between tendons of considerable length. It arises by a series of small tendons from the transverse processes of the sixth to the tenth thoracic vertebrae, and is inserted, by tendons, into the spinous processes of the upper four thoracic and lower two cervical vertebrae. The semispinalis muscles are innervated by the dorsal rami of the cervical spinal nerves. List of muscles of the human body Semispinalis muscles The semispinalis muscles are a group of three muscles"
"Vastus lateralis muscle The vastus lateralis (), also called the <nowiki>""vastus externus""</nowiki> is the largest and most powerful part of the quadriceps femoris, a muscle in the thigh. Together with other muscles of the quadriceps group, it serves to extend the knee joint, moving the lower leg forward. It arises from a series of flat, broad tendons attached to the femur, and attaches to the outer border of the patella. It ultimately joins with the other muscles that make up the quadriceps in the quadriceps tendon, which travels over the knee to connect to the tibia. The vastus lateralis is"
"Pectoralis major The pectoralis major () is a thick, fan-shaped muscle, situated at the chest (anterior) of the human body. It makes up the bulk of the chest muscles and lies under the breast. Below (deep to) the pectoralis major is the pectoralis minor, a thin, triangular muscle. In sports as well as bodybuilding, the pectoral muscles may colloquially be referred to as ""pecs"", ""pectoral muscle"" or ""chest muscle"" due to its being the larger and most superficial muscle in the chest area. It arises from the anterior surface of the sternal half of the clavicle; from breadth of the"
"Gluteus maximus The gluteus maximus (also known collectively with the gluteus medius and minimus, as the gluteal muscles, and sometimes referred to informally as the ""glutes"") is the main extensor muscle of the hip. It is the largest and most superficial of the three gluteal muscles and makes up a large portion of the shape and appearance of each side of the hips. Its thick fleshy mass, in a quadrilateral shape, forms the prominence of the buttocks. Its large size is one of the most characteristic features of the muscular system in humans, connected as it is with the power"
"the most active muscle in forearm supination during unresisted supination, while biceps becomes increasingly active with heavy loading. Supination strength decreases by 64% if supinator is disabled by, for example, injury. The term ""supinator"" can also refer more generally to a muscle that causes supination of a part of the body. In older texts, the term ""supinator longus"" was used to refer to the brachioradialis, and ""supinator brevis"" was used to describe the muscle now known as the supinator. Supinator muscle In human anatomy, the supinator is a broad muscle in the posterior compartment of the forearm, curved around the"

"muscles have broad attachments compared to other muscle types and can shorten to about 40%-60% of their resting length. Strap muscles, such as the laryngeal muscles, have been thought to control the fundamental frequency used in speech production, as well as singing. Another example of this muscle is the longest muscle in the human body, the sartorius. Fusiform muscles are wider and cylindrically shaped in the center and taper off at the ends. This overall shape of fusiform muscles is often referred to as a spindle. The line of action in this muscle type runs in a straight line between"
"tendons. In turn, the tendons connect to the periosteum layer surrounding the bones, permitting the transfer of force from the muscles to the skeleton. Together, these fibrous layers, along with tendons and ligaments, constitute the deep fascia of the body. The muscular system consists of all the muscles present in a single body. There are approximately 650 skeletal muscles in the human body, but an exact number is difficult to define. The difficulty lies partly in the fact that different sources group the muscles differently and partly in that some muscles, such as palmaris longus, are not always present. A"
"push up requires the work of many muscle groups, with one of the primary muscle groups being the chest muscles, the pectoralis major and the minor. These are the two large chest muscles and the main pushing muscle group of the upper body. When pushing and lowering the body during a push up, the pectoralis major is doing most of the work. As a result, these muscles become very strong and can become defined lean muscle after doing push-ups regularly. The push-up depends on stabilizer muscles as you push and lower the body. The erector spinae is the main stabilizer"
"Physical strength Physical strength is the measure of an animal's exertion of force on physical objects. Increasing physical strength is the goal of strength training. An individual's physical strength is determined by two factors; the cross-sectional area of muscle fibers recruited to generate force and the intensity of the recruitment. Individuals with a high proportion of type I slow twitch muscle fibers will be relatively weaker than a similar individual with a high proportion of type II fast twitch fibers, but would have a greater inherent capacity for physical endurance. The genetic inheritance of muscle fiber type sets the outermost"
"There are approximately 639 skeletal muscles in the human body. Heart muscles are distinct from skeletal muscles because the muscle fibers are laterally connected to each other. Furthermore, just as with smooth muscles, their movement is involuntary. Heart muscles are controlled by the sinus node influenced by the autonomic nervous system. Smooth muscles are controlled directly by the autonomic nervous system and are involuntary, meaning that they are incapable of being moved by conscious thought. Functions such as heartbeat and lungs (which are capable of being willingly controlled, be it to a limited extent) are involuntary muscles but are not"
"Core (anatomy) In common parlance, the core of the body is broadly considered to be the torso. Functional movements are highly dependent on this part of the body, and lack of core muscular development can result in a predisposition to injury. The major muscles of the core reside in the area of the belly and the mid and lower back (not the shoulders), and peripherally include the hips, the shoulders and the neck. Major muscles included are the pelvic floor muscles, transversus abdominis, multifidus, internal and external obliques, rectus abdominis, erector spinae (sacrospinalis) especially the longissimus thoracis, and the diaphragm."
"Abdominal external oblique muscle The external oblique muscle (of the abdomen) (also external abdominal oblique muscle) is the largest and the outermost of the three flat muscles of the lateral anterior abdomen. The external oblique is situated on the lateral and anterior parts of the abdomen. It is broad, thin, and irregularly quadrilateral, its muscular portion occupying the side, its aponeurosis the anterior wall of the abdomen. In most humans (especially females), the oblique is not visible, due to subcutaneous fat deposits and the small size of the muscle. It arises from eight fleshy digitations, each from the external surfaces"
"intracapsular. The extracapsular ligaments are the iliofemoral, ischiofemoral, and pubofemoral ligaments attached to the bones of the pelvis (the ilium, ischium, and pubis respectively). All three strengthen the capsule and prevent an excessive range of movement in the joint. Of these, the Y-shaped and twisted iliofemoral ligament is the strongest ligament in the human body. In the upright position, it prevents the trunk from falling backward without the need for muscular activity. In the sitting position, it becomes relaxed, thus permitting the pelvis to tilt backward into its sitting position. The iliofemoral ligament prevents excessive adduction and internal rotation of"
"the muscle of the heart. It is self-contracting, autonomically regulated and must continue to contract in rhythmic fashion for the whole life of the organism. Hence it has special features. Muscle tissue Muscle tissue is a soft tissue that composes muscles in animal bodies, and gives rise to muscles' ability to contract. This is opposed to other components or tissues in muscle such as tendons or perimysium. It is formed during embryonic development through a process known as myogenesis. Muscle tissue varies with function and location in the body. In mammals the three types are: skeletal or striated muscle; smooth"
"crest. The iliocostalis has three different insertions according to the parts: The longissimus muscle is the intermediate and the largest of the three columns. It has three parts with different origin and insertion: The spinalis muscle is the smallest and most medial column. It has three parts: From lateral to medial, the erector spinae muscles can be remembered using the mnemonic, I Love Spine. I lliocostalis, Love Longissimus and Spine Spinalis. Examples of exercises by which the erector spinae can be strengthened for therapeutic or athletic purposes include, but are not limited to: Erector spinae muscles The erector spinae ("
"Muscles of the hand The muscles of the hand are the skeletal muscles responsible for the movement of the hand and fingers. The muscles of the hand can be subdivided into two groups: the extrinsic and intrinsic muscle groups. The extrinsic muscle groups are the long flexors and extensors. They are called extrinsic because the muscle belly is located on the forearm. The intrinsic group are the smaller muscles located within the hand itself. The muscles of the hand are innervated by the radial, median, and ulnar nerves from the brachial plexus. The intrinsic muscle groups are the thenar (thumb)"
"the proximal interphalangeal joints and extending the distal interphalangeal joints. Contrahens The contrahentes (singular contrahens) are muscles widely present in the hands of mammals, including monkeys. They are on the palmar/plantar side. There is one each for digits I, II, IV and V, but not III. They pull the fingers/toes down and together. In humans, the adductor pollicis muscle in the hand and the adductor hallucis in the foot are well-developed remnants of the first contrahens, though they have lost the insertion on the distal phalanx of the thumb or big toe. The other contrahentes only appear as rare atavistic"
"Plantaris muscle The plantaris is one of the superficial muscles of the superficial posterior compartment of the leg, one of the fascial compartments of the leg. It is composed of a thin muscle belly and a long thin tendon. While not as thick as the achilles tendon, the plantaris tendon (which tends to be between 30 and 45 cm in length) is the longest tendon in the human body. Not including the tendon, the plantaris muscle is approximately 5–10 cm long and is absent in 8-12% of the population. It is one of the plantar flexors in the posterior compartment"
