Pelvic Nerve Anatomy

The branches of the sacral plexus that do concern us here are the pudendal nerve which is the principal nerve of the perineum and also the small motor nerves to the pelvic diaphragm. Rectal and uterovaginal in the female are in communication with each other plexus rectal inferior hypogastric pelvic plexus posterior part.

The pelvic splanchnic nerves arise from the anterior rami of the sacral spinal nerves s2 s4 and enter the sacral plexus.

Pelvic nerve anatomy. The skin tissues and organs in the pelvis are supplied by the vasculature of the pelvis and innervated by many nerves of the pelvis including the pudendal nerve. Like the arterial analogues the external iliac vein primarily drains the lower limbs while the internal iliac vein drains the pelvic viscera walls gluteal region and perineum. The perineal nerve innervates muscles of the perineum and pelvic floor.

These nerves are a continuation of the lumbar sympathetic trunks. Heres the pudendal nerve. The inferior aspect of the pelvic cavity is called the pelvic diaphragm.

This nerve sits in front of the sacral promontory. Veins lymphatics and nerves of the pelvis. The muscles of the abdomen and back attach to the pelvis and work together with the muscles of the pelvis.

This section of the nervous system features the most inferior portion of the spinal cord along with many major nerves plexuses and ganglia that serve the vital organs of the abdominopelvic cavity. These plexuses are formed when the right. The autonomic nerve plexuses of the pelvis prostatic rectal and vesical in the male.

Pelvic nerve pain is caused by damage or dysfunction to pelvic nerves which can happen through. A small branch or branches from s3 or 4 supply most of the levator ani muscle and the coccygeus muscle on their pelvic surfaces. The pelvic venous system is responsible for taking blood from the pelvic walls and viscera back to the main circulation.

Levator ani muscles including the iliococcygeus pubococcygeus and puborectalis. The nervous system of the abdomen lower back and pelvis contains many important nerve conduits that service this region of the body as well as the lower limbs. They travel to their sides corresponding inferior hypogastric plexus located bilaterally on the walls of the rectum.

There are many organs that sit in the pelvis including much of the urinary system and lots of the male or female reproductive systems. From there they contribute to the innervation of the pelvic and genital organs. Some pelvic muscles such as psoas major and iliacus help flex the trunk and thigh.

Chronic pelvic nerve pain is pain caused by nerve damage in the pelvis or dysfunction that persists for longer than the expected healing time or is present for at least three to six months. Pelvic autonomic nerves include the following.
