Locate and name each bone that forms the pelvis.
The pelvis is the lower part of the trunk of the human body, between the abdomen and the thighs. Bones which form the pelvis are two hip bones (right and left), sacrum and coccyx. The hip bone is a large bone articulated behind with the sacrum, and in front with its fellow of the opposite side, formed by three parts: ilium, ischium, and pubis (the ilium at the rear, the ischium at the lower front and the pubis above it). The sacrum is located at the inferior end of the spine (below L5 and in between hip bones). The coccyx is located at the bottom spine, right above buttocks.
Step 11 of 2
The sacrum, coccyx, and pelvic girdle together form the bowl-shaped pelvis.
Sacrum- is a triangular structure, composed of five fused vertebrae, that forms the base of the vertebral column
Coccyx- is the lowest part of the vertebral column and is usually composed of four fused vertebrae
The pelvic girdle consists of two hip bones (coxal bones, pelvic bones, or innominate bones) that articulate with each other anteriorly and with the sacrum posteriorly.
Each hip bone develops from three parts—an ilium, an ischium, and a pubis . These parts fuse in the region of a cup-shaped cavity called the acetabulum.
5)The ilium , which is the largest and uppermost portion of the hip bone
The ischium forms the lowest portion of the hip bone
The pubis constitutes the anterior portion of the hip bone.
