Jul 8, 2023 · The sacral plexus is a network of nerve fibres that supplies the skin and muscles of the pelvis and lower limb. It is located on the surface of the posterior pelvic wall, anterior to the piriformis muscle.

Oct 30, 2023 · The sacral plexus is a network of nerves formed by the lumbosacral trunk (L4, L5) and sacral spinal nerves (S1 - S4). The sacral plexus is located on the posterior pelvic wall, posterior to the internal iliac vessels and ureter, and anterior to the piriformis muscle.

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]

Apr 28, 2023 · Often described as part of the lumbosacral plexus, the sacral plexus is located lower in the body than any of the other nerve plexi. The sacral plexus is formed by the lowest lumbar spinal nerves, L4 and L5, as well as sacral nerves S1 through S4.

Jan 22, 2025 · The sacral plexus is a network of nerves formed by the union of the ventral rami of the L4, L5, S1, S2, S3, and a part of S4 spinal nerves. It is responsible for supplying nerves to the pelvis, lower limb, and parts of the genital and urinary systems.

The sacral plexus is situated on the posterolateral wall of the pelvic cavity, lying anterior to the Piriformis. The sacral contributions pass out of the anterior sacral foramina and course laterally & inferiorly on the pelvic wall.

Jan 11, 2025 · The sacral plexus is formed by the anterior sacral roots from S1 to S3, and the lumbar roots from L5 are associated with an anastomotic branch from L4 (furcal nerve).
