The pelvis is classified as an irregular bone structure. It is composed mainly of the pelvic girdle (hip bone) and pelvic spine. The pelvic girdle itself is made from three fused bones: the ilium, ischium, and pubis. Along with the sacrum and coccyx (part of the pelvic spine), these bones form the basin- shaped bony pelvis, which provides support and protection for pelvic organs and serves important biomechanical functions.
Pelvis Bone Type Details
- The pelvis is not a single bone but a complex structure made from multiple bones fused together.
- The hip bone (pelvic girdle) is formed by three bones — ilium (largest), ischium, and pubis — which fuse during puberty.
- The sacrum and coccyx complete the pelvic ring posteriorly.
- This bony pelvis functions as a weight-bearing structure, supports the trunk, and houses reproductive and urinary organs.
Thus, the pelvis is an irregular type of bone composed of fused bones that form a strong, stable ring essential for support and movement.
