In which part of the human body can the 'Tragus' be found?
"Tragus piercing A tragus piercing is the perforation of the tragus, which projects immediately in front of the ear canal, for the purpose of inserting and wearing a piece of jewelry. The piercing itself is usually made with a small gauge hollow piercing needle, and typical jewelry would be a small diameter captive bead ring or small gauge post style piercing jewelry. A related piercing is known as the antitragus piercing. The popularity of tragus piercings began to increase around 2005, according to a BBC report. Barbells, captive bead rings and earring studs are the most common types of jewelry"
"Thorax The thorax or chest (from the Greek θώραξ ""thorax"" ""breastplate, cuirass, corslet"" via ) is a part of the anatomy of humans and various other animals located between the neck and the abdomen. The thorax includes the thoracic cavity and the thoracic wall. It contains organs including the heart, lungs, and thymus gland, as well as muscles and various other internal structures. Many diseases may affect the chest, and one of the most common symptoms is chest pain.

The anterior segment, closest to the head, is the prothorax, with the major features being the first pair of legs and the pronotum. The middle segment is the mesothorax, with the major features being the second pair of legs and the anterior wings. The third and most posterior segment, abutting the abdomen, is the metathorax, which features the third pair of legs and the posterior wings. Each segment is dilineated by an intersegmental suture. Each segment has four basic regions. The dorsal surface is called the tergum"
"that lies over the heart called the cardiac plexus. The vagus nerve is a long, wandering nerve that emerges from the brainstem and provides parasympathetic stimulation to a large number of organs in the thorax and abdomen, including the heart. The nerves from the sympathetic trunk emerge through the T1-T4 thoracic ganglia and travel to both the sinoatrial and atrioventricular nodes, as well as to the atria and ventricles. The ventricles are more richly innervated by sympathetic fibers than parasympathetic fibers. Sympathetic stimulation causes the release of the neurotransmitter norepinephrine (also known as noradrenaline) at the neuromuscular junction of the"

The callosal sulcus separates the corpus callosum from the cingulate gyrus. On either side of the corpus callosum, the fibers radiate in the white matter and pass to the various parts of the cerebral cortex; those curving forward from the genu into the frontal lobes constitute the ""forceps minor"" (also ""forceps anterior"") and those curving backward from the splenium into the occipital lobes, the ""forceps major"" (also ""forceps posterior"").

The human TRG locus is located on chromosome 7 and includes 14 variable segments, of which eight are potentially active, five joining segments, and two constant segments. T cells expressing the γ-chain (TRG+ cells) make up 3-10% of normal adult peripheral blood lymphocytes, with the majority (>80%) of the Vγ2Vδ2+ subtype (referred to as Vδ2+ T cells).

In turn, the notum of the prothorax is called the pronotum, the notum for the mesothorax is called the mesonotum and the notum for the metathorax is called the metanotum. Continuing with this logic, the mesopleura and metapleura, as well as the mesosternum and metasternum, are used. The abdomen is the largest tagma of the insect, which typically consists of 11–12 segments and is less strongly sclerotized than the head or thorax. Each"

The esophagus also lies in front of parts of the hemiazygos veins and the intercostal veins on the right side. The vagus nerve divides and covers the esophagus in a plexus. The esophagus has four points of constriction. When a corrosive substance, or a solid object is swallowed, it is most likely to lodge and damage one of"

Abdomen The abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. The region occupied by the abdomen is termed the abdominal cavity. In arthropods it is the posterior tagma of the body; it follows the thorax or cephalothorax. The abdomen stretches from the thorax at the thoracic diaphragm to the pelvis at the pelvic brim. The pelvic brim stretches from the lumbosacral joint (the intervertebral disc between"
"Crus of diaphragm The crus of diaphragm (pl. crura), refers to one of two tendinous structures that extends below the diaphragm to the vertebral column. There is a right crus and a left crus, which together form a tether for muscular contraction. They take their name from their leg-shaped appearance – ""crus"" meaning ""leg"" in Latin. The crura originate from the front of the bodies and intervertebral fibrocartilage of the lumbar vertebrae. They are tendinous and blend with the anterior longitudinal ligament of the vertebral column. The medial tendinous margins of the crura pass anteriorly and medialward, and meet in"
"Crotch In humans, the crotch is the bottom of the pelvis, the region of the body where the legs join the torso, and is often considered to include the groin and genitals. ""Crotch"" is derived from ""crutch""; it ""was first used in 1539 to refer to a forked stick used as a farm implement."" This region of the body is also described with other terms such as ""groin"" or the lower ventral area. The human crotch has been depicted in artwork. In Paleolithic art, forms called tectiforms or quadrilaterals have sometimes been interpreted to be ""quick visual guides, reminders to"
"mammals, the thorax is the region of the body formed by the sternum, the thoracic vertebrae, and the ribs. It extends from the neck to the diaphragm, and does not include the upper limbs. The heart and the lungs reside in the thoracic cavity, as well as many blood vessels. The inner organs are protected by the rib cage and the sternum. Thoracic vertebrae are also distinguished in birds, but not in reptiles. In insects, crustaceans, and the extinct trilobites, the thorax is one of the three main divisions (or tagmata) of the creature's body, each of which is in"
"Petrous part of the temporal bone The petrous part of the temporal bone is pyramid-shaped and is wedged in at the base of the skull between the sphenoid and occipital bones. Directed medially, forward, and a little upward, it presents a base, an apex, three surfaces, and three angles, and houses in its interior, the components of the inner ear. The petrous portion is among the most basal elements of the skull and forms part of the endocranium. Petrous comes from the Latin word ""petrosus"", meaning ""stone-like, hard"". It is one of the densest bones in the body. The petrous"
"the triceps surae, is found on the lower leg, the triceps brachii is commonly called the triceps. Historically, the plural form of ""triceps"" was ""tricipites"", a form not in general use today; instead, ""triceps"" is both singular and plural (i.e., when referring to both arms). In the horse, 84%, 15%, and 3% of the total triceps muscle weight correspond to the long, lateral and medial heads, respectively. Many mammals, such as dogs, cattle, and pigs, have a fourth head, the accessory head. It lies between the lateral and medial heads. In humans, the anconeus is sometimes loosely called ""the fourth"
"Thorax (insect anatomy) The thorax is the midsection (tagma) of the insect body. It holds the head, legs, wings and abdomen. It is also called mesosoma in other arthropods. It is formed by the prothorax, mesothorax and metathorax and comprises the scutellum; the cervix, a membrane that separates the head from the thorax; and the pleuron, a lateral sclerite of the thorax. In dragonflies and damselflies the mesothorax and metathorax are fused together to form the synthorax. In some insect pupae, like the mosquitoes', the head and thorax can be fused in a cephalothorax.

The Hexapoda, including insects, also have three tagmata, usually termed the head, thorax, and abdomen. The bodies of many arachnids, such as spiders, have two tagmata, as do the bodies of some crustaceans: in both groups the anterior tagma may be called the cephalothorax (meaning head plus chest) or the prosoma or prosome (meaning ""fore-part of body""). The posterior tagma may be called the abdomen. In those arachnids that have two tagmata, the abdomen is also called the"
"Throat In vertebrate anatomy, the throat is the front part of the neck, positioned in front of the vertebra. It contains the pharynx and larynx. An important section of it is the epiglottis, which is a flap separating the esophagus from the trachea (windpipe) preventing food and drink being inhaled into the lungs. The throat contains various blood vessels, pharyngeal muscles, the nasopharyngeal tonsil, the tonsils, the palatine uvula, the trachea, the esophagus, and the vocal cords. Mammal throats consist of two bones, the hyoid bone and the clavicle. The ""throat"" is sometimes thought to be synonymous for the isthmus"
"Vagus nerve The vagus nerve ( ), historically cited as the pneumogastric nerve, is the tenth cranial nerve or CN X, and interfaces with parasympathetic control of the heart, lungs, and digestive tract. The vagus nerves are paired but are normally referred to in the singular. It is the longest nerve of the autonomic nervous system in the human body. Upon leaving the medulla oblongata between the pyramid and the inferior cerebellar peduncle, the vagus nerve extends through the jugular foramen, then passes into the carotid sheath between the internal carotid artery and the internal jugular vein down to the"
"In humans, as in other animals, partial twinning can result in formation of two heads supported by a single torso. Two ways this can happen are dicephalus parapagus, where there are two heads side by side, and craniopagus parasiticus, where the heads are joined directly. In dicephalus parapagus dipus, the two heads are side by side, on a torso with two legs, with varying levels of twinning of organs and structures within the torso. The shared body may have four arms altogether, or three arms, or two arms only. There are Greek-based medical terms for the variations, e.g. dibrachius means"
