What are the fibrous bands called that connects muscles to bones
"to each other by a net of fibrous tissue, preventing completely free movement. Fingers do not contain muscles (other than arrector pili). The muscles that move the finger joints are in the palm and forearm. The long tendons that deliver motion from the forearm muscles may be observed to move under the skin at the wrist and on the back of the hand. Muscles of the fingers can be subdivided into extrinsic and intrinsic muscles. The extrinsic muscles are the long flexors and extensors. They are called extrinsic because the muscle belly is located on the forearm. The fingers have"
"Fibrous joint Fibrous joints are connected by dense connective tissue, consisting mainly of collagen. These are fixed joints where bones are united by a layer of white fibrous tissue of varying thickness. In the skull the joints between the bones are called sutures. Such immovable joints are also referred to as synarthroses. Most fibrous joints are also called ""fixed"" or ""immovable"". These joints have no joint cavity and are connected via fibrous connective tissue. The skull bones are connected by fibrous joints called sutures. In fetal skulls the sutures are wide to allow slight movement during birth. They later become"
"the tissue linking the structures is ligamentous. A gomphosis is a specialized fibrous joint in which a conical process or peg of one bone fits into a hole or socket in another bone. (gomphos is a Greek word meaning bolt). Small quantity of fibrous tissue holds the bones together. No movement is possible at such peg-and-socket joints. Fibrous joint Fibrous joints are connected by dense connective tissue, consisting mainly of collagen. These are fixed joints where bones are united by a layer of white fibrous tissue of varying thickness. In the skull the joints between the bones are called sutures."
"Enthesis The enthesis (plural entheses) is the connective tissue between tendon or ligament and bone. There are two types of entheses: ""Fibrous entheses"" and ""fibrocartilaginous entheses"". In a fibrous enthesis, the collagenous tendon or ligament directly attaches to the bone. In a fibrocartilaginous enthesis, the interface presents a gradient that crosses four transition zones: A disease of the entheses is known as an ""enthesopathy"" or ""enthesitis"". Enthetic degeneration is characteristic of spondyloarthropathy and other pathologies. The enthesis is the primary site of disease in ankylosing spondylitis. Entheses are widely recorded in the field of bioarchaeology where the presence of anomalies"
"in the maxillary bone and mandible. The fibrous connection between a tooth and its socket is a periodontal ligament. Specifically, the connection is made between the maxilla or mandible to the cementum of the tooth. The motion of a gomphosis is minimal, though considerable movement can be achieved over time—the basis of using braces to realign teeth. The joint can be considered a synarthrosis. The gomphosis is the only joint-type in which a bone does not join another bone, as teeth are not technically bone. In modern, more anatomical, joint classification, the gomphosis is simply considered a fibrous joint because"
"Sharpey's fibres Sharpey's fibres (bone fibres, or perforating fibres) are a matrix of connective tissue consisting of bundles of strong predominantly type I collagen fibres connecting periosteum to bone. They are part of the outer fibrous layer of periosteum, entering into the outer circumferential and interstitial lamellae of bone tissue. Sharpey's fibres are also used to attach muscle to the periosteum of bone by merging with the fibrous periosteum and underlying bone as well. A good example is the attachment of the rotator cuff muscles to the blade of the scapula. In the teeth, Sharpey's fibres are the terminal ends"
"Chordae tendineae The chordae tendineae (tendinous cords), colloquially known as the heart strings, are tendon-resembling fibrous cords of connective tissue that connect the papillary muscles to the tricuspid valve and the bicuspid valve in the heart. Chordae tendineae are approximately 80% collagen, while the remaining 20% is made up of elastin and endothelial cells. The ""tendon of Todaro"" is a continuation of the Eustachian valve of the inferior vena cava and the Thebesian ring of the coronary sinus. Along with the opening of the coronary sinus and the septal cusp of the tricuspid valve, it makes up the ""triangle of"
"Tendon A tendon or sinew is a tough band of fibrous connective tissue that usually connects muscle to bone and is capable of withstanding tension. Tendons are similar to ligaments; both are made of collagen. Ligaments join one bone to bone, while tendons connect muscle to bone for a proper functioning of the body. Histologically, tendons consist of dense regular connective tissue fascicles encased in dense irregular connective tissue sheaths. Normal healthy tendons are composed mostly of parallel arrays of collagen fibers closely packed together. They are anchored to bone by Sharpey's fibres. The dry mass of normal tendons, which"
"not arranged into sarcomeres. The sarcomeres are what give skeletal and cardiac muscles their striated appearance, which was first described by Leeuwenhoek. The relationship between the proteins and the regions of the sarcomere are as follows: Upon muscle contraction, the A-bands do not change their length (1.85 micrometer in mammalian skeletal muscle), whereas the I-bands and the H-zone shorten. This causes the Z lines to come closer together. The protein [tropomyosin] covers the myosin binding sites of the actin molecules in the muscle cell. To allow the muscle cell to contract, tropomyosin must be moved to uncover the binding sites"
"Fascia A fascia (; plural fasciae ; adjective fascial; from Latin: ""band"") is a band or sheet of connective tissue, primarily collagen, beneath the skin that attaches, stabilizes, encloses, and separates muscles and other internal organs. Fascia is classified by layer, as ""superficial fascia"", deep fascia, and ""visceral"" or ""parietal"" fascia, or by its function and anatomical location. Like ligaments, aponeuroses, and tendons, fascia is made up of fibrous connective tissue containing closely packed bundles of collagen fibers oriented in a wavy pattern parallel to the direction of pull. Fascia is consequently flexible and able to resist great unidirectional tension"
"The atrioventricular rings serve for the attachment of the muscular fibers of the atria and ventricles, and for the attachment of the bicuspid and tricuspid valves. The left atrioventricular ring is closely connected, by its right margin, with the aortic arterial ring; between these and the right atrioventricular ring is a triangular mass of fibrous tissue, the Fibrous trigone, which represents the ""os cordis"" seen in the heart of some of the larger animals, as the ox and elephant. Lastly, there is the tendinous band, already referred to, the posterior surface of the conus arteriosus. The fibrous rings surrounding the"
"to bones. The extra-cellular connective tissue between muscle fibers binds to tendons at the distal and proximal ends, and the tendon binds to the periosteum of individual bones at the muscle's origin and insertion. As muscles contract, tendons transmit the forces to the relatively rigid bones, pulling on them and causing movement. Tendons can stretch substantially, allowing them to function as springs during locomotion, thereby saving energy. Joints are structures that connect individual bones and may allow bones to move against each other to cause movement. There are three divisions of joints, diarthroses which allow extensive mobility between two or"
"Extrafusal muscle fiber Extrafusal muscle fibers are the skeletal standard muscle fibers that are innervated by alpha motor neurons and generate tension by contracting, thereby allowing for skeletal movement. They make up the large mass of skeletal muscle tissue and are attached to bone by fibrous tissue extensions (tendons). Each alpha motor neuron and the extrafusal muscle fibers innervated by it make up a motor unit. The connection between the alpha motor neuron and the extrafusal muscle fiber is a neuromuscular junction, where the neuron's signal, the action potential, is transduced to the muscle fiber by the neurotransmitter acetylcholine. Extrafusal"
"ornithischian dinosaurs, ossified axial muscle tendons form a latticework along the neural and haemal spines on the tail, presumably for support. Tendon A tendon or sinew is a tough band of fibrous connective tissue that usually connects muscle to bone and is capable of withstanding tension.

"Cartilaginous joint Cartilaginous joints are connected entirely by cartilage (fibrocartilage or hyaline). Cartilaginous joints allow more movement between bones than a fibrous joint but less than the highly mobile synovial joint. Cartilaginous joints also forms the growth regions of immature long bones and the intervertebral discs of the spinal column. Known as ""synchondrosis"". These bones are connected by hyaline cartilage and sometimes occur between ossification centers. This cartilage may ossify with age. Examples in humans are the ""growth plates"" between ossification centers in long bones. These joints here allow for only a little movement, such as in the spine or"
"ninth abdominal segment. It retains the aedeagus and the clasper attaches to it. Vinculum (ligament) In anatomy, a vinculum (pl. vincula) is a band of connective tissue, similar to a ligament, that connect a flexor tendon to a phalanx bone. They contain tiny vessels which supply blood to the tendon. In vertebrate anatomy, they are referred to as mesotendons. For example, in the fingers and toes of humans and related vertebrates, vincula are responsible for the direct vascularization of the flexor digitorum superficialis and profundus tendons to the intermediate and distal phalanges in each finger. These vincula are four folds"
"called focal adhesions) in the cell membrane of the smooth muscle cell, called the sarcolemma. The adherens junctions consist of large number of proteins including α-actinin, vinculin and cytoskeletal actin. The adherens junctions are scattered around ""dense bands"" that are circumfering the smooth muscle cell in a rib-like pattern. The dense band (or dense plaques) areas alternate with regions of membrane containing numerous caveolae. When complexes of actin and myosin contract, force is transduced to the sarcolemma through intermediate filaments attaching to such dense bands. During contraction, there is a spatial reorganization of the contractile machinery to optimize force development."

"to muscles. Synovial membranes are found in joint capsules, where they contain synovial fluid, which lubricates joints. Bones are covered by a tough membrane called periosteum, which covers the entire bone excluding areas of articulation. Ligaments attach bone to bone, and are vital in stabilizing joints as well as supporting structures. They are made up of fibrous material that is generally quite strong. Due to their relatively poor blood supply, ligament injuries generally take a long time to heal. Ligaments of the upper body include: Ligaments of the legs include: The axial skeleton contains the skull, vertebral column, sternum, and"
"Synovial joint A synovial joint, also known as diarthrosis, joins bones with a fibrous joint capsule that is continuous with the periosteum of the joined bones, constitutes the outer boundary of a synovial cavity, and surrounds the bones' articulating surfaces. The synovial cavity/joint is filled with synovial fluid. The joint capsule is made up of an outer layer, the articular capsule, which keeps the bones together structurally, and an inner layer, the synovial membrane, which seals in the synovial fluid. They are the most common and most movable type of joint in the body of a mammal. As with most"
"most numerous in areas where the bones are subjected to the greatest forces of separation. In the spine, similar fibres join the intervertebral disc to the adjacent vertebrae. Each fibre is accompanied by an arteriole and one or more nerve fibres. Scottish anatomist William Sharpey described them in 1846. Sharpey's fibres Sharpey's fibres (bone fibres, or perforating fibres) are a matrix of connective tissue consisting of bundles of strong predominantly type I collagen fibres connecting periosteum to bone.

Peroneal retinacula The peroneal retinacula (singular: peroneal retinaculum) are fibrous retaining bands which bind down the tendons of the peroneus longus and brevis as they run across the side of the ankle. (""Retinaculum"" is Latin for ""retainer""). These bands consist of superior and inferior fibres. The superior fibres are attached above to the lateral malleolus and below to the lateral surface of the calcaneus. The inferior fibres are continuous in front with those of the inferior extensor retinaculum of the foot; behind they are"
"are bundles of contractile fibers that are attached to bones by tendons. These bundles have different types of fibers within them, and horses have adapted over the years to produce different amounts of these fibers. Type II-b fibers are fast twitch fibers. These fibers allow muscles to contract quickly, resulting in a great deal of power and speed. Type I fibers are slow-twitch fibers. They allow muscles to work for longer periods of time resulting in greater endurance. Type II-a fibers are intermediate, representing a balance between the fast-twitch fibers and the slow-twitch fibers. They allow the muscles to generate"
"a sling or collar around the neck of the femur. Anteriorly they blend with the deep surface of the iliofemoral ligament, and gain an attachment to the anterior inferior iliac spine. The longitudinal fibers are greatest in amount at the upper and front part of the capsule, where they are reinforced by distinct bands, or accessory ligaments, of which the most important is the iliofemoral ligament. The other accessory bands are known as the pubocapsular and the ischiocapsular ligaments. The external surface of the capsule is rough, covered by numerous muscles, and separated in front from the psoas major and"
"are periodontal ligament stem cells located near the periodontal ligament which are involved in the adult regeneration of periodontal ligament. The study of ligaments is known as (from Greek , ""desmos"", ""bond""; and , ""-logia""). ""Ligament"" most commonly refers to a band of dense regular connective tissue bundles made of collagenous fibers, with bundles protected by dense irregular connective tissue sheaths. Ligaments connect bones to other bones to form joints, while tendons connect bone to muscle. Some ligaments limit the mobility of articulations or prevent certain movements altogether. Capsular ligaments are part of the articular capsule that surrounds synovial joints."
"Lumbar fascia The lumbar fascia is an anatomic structure of the lumbar region. It consists of a band or sheet of connective tissue fibres, primarily collagen, that attaches, stabilizes, encloses and separates muscles not limited to the lumbar region as the name suggests, but extending upwards over the thorax to the neck and downwards over the muscles covering the sacrum. The upper thoracic portion is thin while the lumbar and sacral regions are thicker and stronger. The lumbar fascia binds the deep muscles of the back to the spine and to the transverse processes of the vertebrae. Additionally the lumbar"
"ligaments include osteoblasts, osteoclasts, fibroblasts, macrophages, cementoblasts, and epithelial cell rests of Malassez. Consisting of mostly Type I and III collagen, the fibers are grouped in bundles and named according to their location. The groups of fibers are named alveolar crest, horizontal, oblique, periapical, and interradicular fibers. The nerve supply generally enters from the bone apical to the tooth and forms a network around the tooth toward the crest of the gingiva. When pressure is exerted on a tooth, such as during chewing or biting, the tooth moves slightly in its socket and puts tension on the periodontal ligaments. The"
"Carpal bones The carpal bones are the eight small bones that make up the wrist (or carpus) that connects the hand to the forearm. The term ""carpus"" is derived from the Latin carpus and the Greek καρπός (karpós), meaning ""wrist"". In human anatomy, the main role of the wrist is to facilitate effective positioning of the hand and powerful use of the extensors and flexors of the forearm, and the mobility of individual carpal bones increase the freedom of movements at the wrist. In tetrapods, the carpus is the sole cluster of bones in the wrist between the radius and"
"ribs. Known as ""symphysis"". Fibrocartilaginous and hyaline joints, usually occurring in the midline. Examples in human anatomy would be the manubriosternal joint (between the manubrium and the sternum), intervertebral discs, and the pubic symphysis. Articulating bones at a symphysis are covered with hyaline cartilage and have a thick, fairly compressible pad of fibrocartilage between them. Cartilaginous joints allow little movement, as summarized above. Cartilaginous joint Cartilaginous joints are connected entirely by cartilage (fibrocartilage or hyaline). Cartilaginous joints allow more movement between bones than a fibrous joint but less than the highly mobile synovial joint. Cartilaginous joints also forms the growth"

Syndemoses are slightly moveable (amphiarthrodial). The distal tibiofibular joint is another example. A gomphosis is a joint between the root of a tooth and the socket in the maxilla or mandible (jawbones). A suture is a type of fibrous joint that is only found in the skull. The bones are bound together by Sharpey's fibres. A tiny amount of movement is permitted at sutures, which contributes to the compliance and elasticity of"
