sacral plexus

(It is interconnected with the lower part of Sacral plexus).

The lower branches of the L4 and the L5 nerves enter the sacral plexus.

The nerve to piriformis originates in the sacral plexus.

These nerve roots are part of a larger nerve network called the sacral plexus.

'The sacral plexus would have been affected, where most of the major nerves go from the spine to the hips and the legs.

From the sacral plexus, the lower motor neuron travels down the sciatic nerve.

The perforating cutaneous nerve arises from the sacral plexus.

The muscles are innervated by the sacral plexus (L4-S2).

The sacral plexus is formed in the pelvis in front of the piriformis muscle.

The nerve to quadratus femoris is a sacral plexus nerve.

The sacral plexus contains ventral rami from spinal nerves L4-S4.

The sacral plexus is formed by:

These anastomoses of nerves form the sacral plexus and the lumbosacral plexus.

The superior gluteal nerve arises from the sacral plexus and only has motor innervation associated with it.

A lower motor neuron exits to the sacral plexus exiting through the spinal levels L5-S2.

The sacral plexus lies on the back of the pelvis between the piriformis muscle and the pelvic fascia.

However, most of the sacral plexus nerves are scarcely recognizable, because they leave the pelvis through the greater sciatic foramen.

The smaller part of the fourth joins with the fifth to form the lumbosacral trunk, which assists in the formation of the sacral plexus.

The nerve was always seen close to and medial to the sciatic nerve when it left the sacral plexus inferior to the piriformis.

It arises from the sacral plexus, and its ventral ramus helps form the coccygeal plexus.

The lumbosacral trunk is nervous tissue that connects the lumbar plexus with the sacral plexus.

These nerves course beside the prostate arising from the sacral plexus and can be damaged in prostatic and colo-rectal surgeries.

The pelvic splanchnic nerves arise from the ventral rami of the S2-S4 and enter the sacral plexus.

Behind the sigmoid colon are the external iliac vessels, the left Piriformis, and left sacral plexus of nerves.

It is kept tonically contracted by sacral plexus (via inferior hypo-gastric plexus) of the sympathetic nervous system.
