Buttocks
The buttocks (singular: buttock) are two rounded portions of the exterior anatomy of most mammals, located on the posterior of the pelvic region. In humans, the buttocks are located between the lower back and the perineum. They are composed of a layer of exterior skin and underlying subcutaneous fat superimposed on a left and right gluteus maximus and gluteus medius muscles. The two gluteus maximus muscles are the largest muscles in the human body. They are responsible for movements such as straightening the body into the upright (standing) posture when it is bent at the waist; maintaining the body in the upright posture by keeping the hip joints extended; and propelling the body forward via further leg (hip) extension when walking or running. In the seated position, the buttocks bear the weight of the upper body and take that weight off the feet. In many cultures, the buttocks play a role in sexual attraction. Many cultures have also used the buttocks as a primary target f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mooning
Mooning is the act of displaying one's bare buttocks by removing clothing, e.g., by lowering the backside of one's trousers and underpants, usually bending over, and also potentially exposing the genitals. Mooning is used in the English-speaking world to express protest, scorn, disrespect, or for provocation, but mooning can be done for shock value, for fun, as a joke or as a form of exhibitionism. The Māori have a form of mooning known as that is a form of insult. Some jurisdictions regard mooning to be indecent exposure, sometimes depending on the context. Word history ''Moon'' has been a common shape metaphor for the buttocks in English since 1743, and the verb ''to moon'' has meant "to expose to (moon)light" since 1601. As documented by McLaren, "'mooning', or exposing one's butt to shame an enemy ... had a long pedigree in peasant culture" throughout the Middle Ages, and in many nations. "Mooning" is also defined as "wandering idly" and "romantically pining". Altho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gluteus Maximus Muscle
The gluteal muscles, often called glutes are a group of three muscles which make up the gluteal region commonly known as the buttocks: the gluteus maximus, gluteus medius and gluteus minimus. The three muscles originate from the ilium and sacrum and insert on the femur. The functions of the muscles include extension, abduction, external rotation, and internal rotation of the hip joint. Structure The gluteus maximus is the largest and most superficial of the three gluteal muscles. It makes up a large part of the shape and appearance of the hips. It is a narrow and thick fleshy mass of a quadrilateral shape, and forms the prominence of the buttocks. The gluteus medius is a broad, thick, radiating muscle, situated on the outer surface of the pelvis. It lies profound to the gluteus maximus and its posterior third is covered by the gluteus maximus, its anterior two-thirds by the gluteal aponeurosis, which separates it from the superficial fascia and skin. The gluteus minimus is t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adipose Tissue
Adipose tissue, body fat, or simply fat is a loose connective tissue composed mostly of adipocytes. In addition to adipocytes, adipose tissue contains the stromal vascular fraction (SVF) of cells including preadipocytes, fibroblasts, vascular endothelial cells and a variety of immune cells such as adipose tissue macrophages. Adipose tissue is derived from preadipocytes. Its main role is to store energy in the form of lipids, although it also cushions and insulates the body. Far from being hormonally inert, adipose tissue has, in recent years, been recognized as a major endocrine organ, as it produces hormones such as leptin, estrogen, resistin, and cytokines (especially TNFα). In obesity, adipose tissue is also implicated in the chronic release of pro-inflammatory markers known as adipokines, which are responsible for the development of metabolic syndrome, a constellation of diseases including, but not limited to, type 2 diabetes, cardiovascular disease and atherosclerosis.

Superior Cluneal Nerves
The superior cluneal nerves are pure sensory nerves that innervate the skin of the upper part of the buttocks. They are the terminal ends of the L1-L3 spinal nerve dorsal rami lateral branches.Waldman SD. Atlas of Uncommon Pain Syndromes. 3rd ed. Philadelphia, PA: Saunders/Elsevier; 2014. They are one of three different types of cluneal nerves (middle and inferior cluneal nerves being the other two). Dysfunction of the superior cluneal nerves is often due to entrapment as the nerves cross the iliac crest – this can result in numbness, tingling or pain in the low back and upper buttocks region. Superior cluneal nerve dysfunction is a clinical diagnosis that can be supported by diagnostic nerve blocks. Anatomy The superior cluneal nerves are a group of nerves that were first described by Maigne et al. in 1989 as a source of low back pain. These nerves are grouped as the superior cluneal nerves due to their trajectory over the iliac spine, as opposed to the lateral, medial and inf ...

Horizontal Gluteal Crease
The gluteal sulcus (also known as the gluteal fold, fold of the buttock or horizontal gluteal crease) is an area of the body of humans and anthropoid apes, described by a horizontal crease formed by the inferior aspect of the buttocks and the posterior upper thigh. The gluteal sulcus is formed by the posterior horizontal skin crease of the hip joint and overlying fat and is not formed by the lower border of the gluteus maximus muscle, which crosses the fold obliquely. It is one of the major defining features of the buttocks. Children with developmental dysplasia of the hips are born with uneven gluteal folds and can be diagnosed with physical examination and sonogram. Gluteal muscles The gluteal muscles can be classified into two main groups. The superficial gluteal muscles are responsible for extension and abduction of the hip, and stabilizing and maintaining the balance of the pelvis during the gait cycle. Deep gluteal muscles control external rotation of the extended hip an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intergluteal Cleft
The intergluteal cleft or just gluteal cleft, also known by a number of synonyms, including natal cleft, butt crack, and cluneal cleft, is the groove between the buttocks that runs from just below the sacrum to the perineum, so named because it forms the visible border between the external rounded protrusions of the gluteus maximus muscles. Other names are the ''anal cleft'', ''crena analis'', ''crena interglutealis'', and ''rima ani''. Colloquially the intergluteal cleft is known as ''bum crack'' (UK) or ''butt crack'' (US). The intergluteal cleft is located superior to the anus. There are several disorders that can affect the intergluteal cleft including inverse psoriasis, caudal regression syndrome, and pilonidal disease. See also * Buttock cleavage * Rectum *Anal canal * * *Anatomical terms of location Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans.

Baboon
Baboons are primates comprising the genus ''Papio'', one of the 23 genera of Old World monkeys. There are six species of baboon: the hamadryas baboon, the Guinea baboon, the olive baboon, the yellow baboon, the Kinda baboon and the chacma baboon. Each species is native to one of six areas of Africa and the hamadryas baboon is also native to part of the Arabian Peninsula. Baboons are among the largest non-hominoid primates and have existed for at least two million years. Baboons vary in size and weight depending on the species. The smallest, the Kinda baboon, is in length and weighs only , while the largest, the chacma baboon, is up to in length and weighs . All baboons have long, dog-like muzzles, heavy, powerful jaws with sharp canine teeth, close-set eyes, thick fur except on their muzzles, short tails, and nerveless, hairless pads of skin on their protruding buttocks called ischial callosities that provide for sitting comfort. Male hamadryas baboons have large white man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Callosity
A callosity is another name for callus, a piece of skin that has become thickened as a result of repeated contact and friction. Primates All Old World monkeys, gibbons, and some chimpanzees have pads on their rears known as ischial callosities. Ischial relates to the ischium: it forms the lower and back part of the hip bone. The pads enable the monkeys to sleep sitting upright on thin branches, beyond reach of predators, without falling. The ischial callosities are one of the most distinctive pelvic features which separates Old World monkeys from New World monkeys. Right whales In whales, the term ''callosity'' refers to the rough, calcified skin patches found on the heads of the three species of right whales. These callosities are a characteristic feature of the whale genus ''Eubalaena''; because they are found on the head of the whale and appear white against the dark background of the whale's skin, they make it very easy to identify these species. The callosities th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
