The pelvis

Last crawled date: 3 years, 5 months ago

The pelvis or pelvic girdle is the irregular bony structure located at the base of the spine (properly known as the caudal end). In the adult human, it is formed by the sacrum and the coccyx, the caudal part of the axial skeleton, and a pair of hip bones, part of the appendicular skeleton or lower extremity. Until puberty, however, each hip bone consists of three separate bones yet to be fused — the ilium, ischium, and the pubis — and the pelvis is thus composed of up to five or seven bones. The ilium is the largest and upper most part, the ischium is the posterior-inferior (back-lower) part, and the pubis is the anterior (front) part of the hip bone. The two hip bones are joined anteriorly at the symphysis pubis and posteriorly to the sacrum. The pelvis incorporates the socket portion of the hip joint (the acetabulum) for each leg (in bipeds) or hind leg (in quadrupeds). It forms the lower limb (or hind-limb) girdle of the skeleton. The pelvis gets its name because of its shape. In Latin, 'pelvis' means 'basin' or 'large bowl'. #3d #Bone #humen #Jeroen_Hut #people #The_pelvis
