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 ] A sacral plexopathy is a disorder affecting the nerves of ...
6423. Anatomical terminology. [edit on Wikidata] The sacral spinal nerve 1 (S1) is a spinal nerve of the sacral segment. [1] It originates from the spinal column from below the 1st body of the sacrum. Sacrum, showing bodies in center.
Anatomical terms of bone. [ edit on Wikidata] The sacrum (pl.: sacra or sacrums[ 1 ]), in human anatomy, is a large, triangular bone at the base of the spine that forms by the fusing of the sacral vertebrae (S1–S5) between ages 18 and 30. [ 2 ] The sacrum situates at the upper, back part of the pelvic cavity, between the two wings of the pelvis.
A spinal nerve is a mixed nerve, which carries motor, sensory, and autonomic signals between the spinal cord and the body. In the human body there are 31 pairs of spinal nerves, one on each side of the vertebral column. [1][2] These are grouped into the corresponding cervical, thoracic, lumbar, sacral and coccygeal regions of the spine. [1]
Ventral rami of L4-S3 with parts of L4 and S4 spinal nerves form the sacral plexus. It is located on the posterior wall of pelvic cavity (pelvis minor). Nervi of the plexus innervate the perineal region, buttocks and the lower limb. The largest nerve of the human body, the sciatic nerve, is the main branch that gives rami to the motor ...
Anatomical terminology. [edit on Wikidata] The sacral spinal nerve 3 (S3) is a spinal nerve of the sacral segment. [1] It originates from the spinal column from below the 3rd body of the sacrum. Sacrum, showing bodies in center.
Anatomical terms of neuroanatomy. [edit on Wikidata] The sacral spinal nerve 2 (S2) is a spinal nerve of the sacral segment. [1] It originates from the spinal column from below the 2nd body of the sacrum. Sacrum, showing bodies in center.
The sacral sympathetic nerves arise from the sacral part of the sympathetic trunk, emerging anteriorly from the ganglia.They travel to their corresponding side's inferior hypogastric plexus, where the preganglionic nerve fibers synapse with the postganglionic sympathetic neurons, whose fibers ascend to the superior hypogastric plexus, the aortic plexus and the inferior mesenteric plexus, where ...
