The same human pelvis, front imaged by X-ray (top), magnetic resonance imaging (middle), and 3-dimensional computed tomography (bottom). The pelvis (pl.: pelves or pelvises) is the lower part of an anatomical trunk, [1] between the abdomen and the thighs (sometimes also called pelvic region), together with its embedded skeleton [2] (sometimes also called bony pelvis or pelvic skeleton).

In human anatomy, the sacral plexus is a nerve plexus which provides motor and sensory nerves for the posterior thigh, most of the lower leg and foot, and part of the pelvis. It is part of the lumbosacral plexus and emerges from the lumbar vertebrae and sacral vertebrae (L4-S4). [ 1 ]
Some sources consider this region part of the pelvic cavity, [citation needed] while others reframe the classification by calling the combination the abdominopelvic cavity. The greater pelvis supports the intestines (specifically, the ileum and sigmoid colon ), and transmits part of their weight to the anterior wall of the abdomen .
The ears are referred to as the auricle or otic region. The nose is referred to as the nasal region. The mouth is referred to as the oral region. The chin is referred to as the mental region. The neck is referred to as the cervical region. The trunk of the body contains, from superior to inferior, the thoracic region encompassing the chest [1]
Laterally, the ligament attaches onto the posterior part of the inner lip of the iliac crest. [1] More precisely, its lateral attachment is by two main bands: [2] the superior band (which is one of the attachments of the quadratus lumborum muscle) attaches onto the iliac crest anterior to the sacroiliac joint.
In human anatomy, the five vertebrae are between the rib cage and the pelvis.They are the largest segments of the vertebral column and are characterized by the absence of the foramen transversarium within the transverse process (since it is only found in the cervical region) and by the absence of facets on the sides of the body (as found only in the thoracic region).
The lumbosacral trunk is formed by the union of the entire anterior ramus of lumbar nerve L5 and a part of L4 [clarification needed]. [1] [2] [3] L4 first issues its branches to the lumbar plexus, then emerges from the medial border of the psoas muscle [3] to unite with the anterior ramus of L5 just superior to the pelvic brim to form the thick, cord-like trunk which [4] crosses the pelvic ...
