Pelvic (hip) bones.

2023年7月30日 · The bony pelvis is key to many functions of the body, as a transitional zone for neurovascular structures traversing between the abdomen and the lower limbs, a junctional point between the spine and lower limb forces during locomotion, and a structure within which lie crucial visceral structures such as the female reproductive organs, urinary ...

2023年7月24日 · The bones of the pelvis are a critical part of the central portion of the skeleton. They serve as a transition from the axial skeleton and the appendicular skeleton of the lower body, serving as an attachment point for some of the strongest muscles in the human body while withstanding the forces generated by them.

2023年3月6日 · The pelvis joints include the pubic symphysis and the lumbosacral, sacroiliac, and sacrococcygeal joints. The bony pelvis also articulates with the lower limb via the acetabulofemoral, or hip, joint on its lateral aspect.
