What does the coccygeal plexus supply?
The coccygeal plexus gives rise to the anococcygeal nerve. This nerve supplies the sacrotuberous ligament as well as the skin over the tailbone. The posterior ramus of the coccygeal nerve with the communicating branch from the S5 spinal nerve supplies the skin over the back of the tailbone.
Where is the coccygeal plexus?
The sacral and coccygeal plexuses are formed from the roots of the L4–S4 segments, located anterior to the piriformis muscle.
What nerves make up the coccygeal plexus?
The coccygeal plexus originates from ventral rami nerve roots of the fourth and fifth sacral nerves and the ventral rami of the first coccygeal nerve. The fourth sacral nerve root emerges from the fourth ventral sacral foramen and splits into a lateral and medial branch (Woon & Stringer, 2014).
What does coccygeal plexus control?
The largest nerve in the sacral plexus is the sciatic nerve that innervates the thigh, lower leg, and the foot. The coccygeal plexus consists of the coccygeal nerve and the fifth sacral nerve, which innervate the skin in the coccygeal region, around the tailbone (called the coccyx).
What does the coccygeal nerve innervate?
The coccygeal plexus primarily innervate the coccygeal vertebrae, a network of nerves originating from the ventral rami of S4, S5, and Co1 along with the dorsal rami of the sacral sympathetic trunk, converging in the area of the iliococcygeus muscle.
What is the coccygeal?
What is the tailbone/coccyx? Your coccyx is made up of three to five fused vertebrae (bones). It lies beneath the sacrum, a bone structure at the base of your spine.
Is coccygeal a plexus?
The coccygeal plexus is a nerve plexus near the coccyx bone.
What is the coccygeal region?
The coccyx is a triangular arrangement of bone that makes up the very bottom portion of the spine below the sacrum. It represents a vestigial tail, hence the common term tailbone.
How can I relieve coccyx pain?
How you can ease tailbone (coccyx) pain yourself
- sit correctly – maintain good posture with your lower back supported.
- use a specially designed coccyx cushion when sitting – sitting on an exercise ball can also help.
- lie on your side to reduce the pressure on your coccyx.
What is a coccyx?
What is the tailbone/coccyx? Your coccyx is made up of three to five fused vertebrae (bones). It lies beneath the sacrum, a bone structure at the base of your spine. Several tendons, muscles and ligaments connect to it.
