2024年1月11日 · The pelvic girdle connects the trunk and the lower limbs and provides support and stability to the human body. Learn more about its anatomy at Kenhub!

Muscles that play a role in providing SIJ stability through increasing compression load across the joint are the transversus abdominis and the pelvic floor muscles (levator ani and coccygeus muscles).

2025年1月16日 · The pelvis is a basin shaped bony structure formed by the combination of two pelvic bones (hip bones or innominate bones) and the sacrum. It is strengthened and supported by several joints and ligaments. It provides attachment to some important muscles in the region, and forms a cavity which accommodates several important internal organs.

2024年9月24日 · Your pelvis is the bony structure inside your hips, buttocks and pubic region. It’s the seat that holds up your upper body when you sit, stand or walk.

2017年8月30日 · This blog post article is an overview of the motions of the joints of the pelvis: the paired left and right sacroiliac joints and the symphysis pubis joint. For more complete coverage of the structure and function of the low back and pelvis, Kinesiology – The Skeletal System and Muscle Function, 3 rd ed. (2017, Elsevier) should be consulted.

2023年7月17日 · Pelvic muscle innervation is complex, involving the autonomic and somatic system: the superior hypogastric plexus with hypogastric nerves, the pelvic splanchnic nerves, and the inferior hypogastric (pelvic) plexus; the pudendal nerve.

The female true pelvis differs from the male in being shallower, having straighter sides, a wider angle between the pubic rami at the symphysis, and a proportionately larger pelvic outlet. The shape of the female bony pelvis can be classified into four broad categories: gynecoid, anthropoid, android, and platypelloid [3] .

The bones of the pelvis (i.e. the sacrum, coccyx, and two innominate bones) form the pelvic ring. The innominate bones close the pelvic ring at the front and sides, while the sacrum and coccyx form the posterior border of the ring. The sacrum is a large bone located at the terminal part of the vertebral canal. It forms the posterior aspect of ...

Unlike the bones of the pectoral girdle, which are highly mobile to enhance the range of upper limb movements, the bones of the pelvis are strongly united to each other to form a largely immobile, weight-bearing structure.
