What does the Coccygeal nerve 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).

Are there Coccygeal nerves?

Coccygeal nerve The bilateral coccygeal nerves, Co, are the 31st pair of spinal nerves. It arises from the conus medullaris, and its ventral ramus helps form the coccygeal plexus. It does not divide into a medial and lateral branch.

What nerve is near the coccyx?

The coccygeal nerve is the one serving the tailbone (ie, coccyx). There are 5 sacral nerves (part of the spinal cord) numbered S1 through S5.

What is sacrococcygeal pain?

Sacrococcygeal pain can arise from the sacrococcygeal joint, from contiguous structures sharing the same innervation, or from distant sites. True coccygodynia consists of pain arising from the sacrococcygeal joint, whereas pseudococcygodynia consists of pain referred to but not arising from the coccyx.

What are the symptoms of nerve root compression?

When a nerve root is compressed, it becomes inflamed. This results in several unpleasant symptoms that may include: Sharp pain in the back, arms, legs or shoulders that may worsen with certain activities, even something as simple as coughing or sneezing. Weakness or loss of reflexes in the arms or legs.

Why does the bottom of my spine hurt?

Tailbone pain — pain that occurs in or around the bony structure at the bottom of the spine (coccyx) — can be caused by trauma to the coccyx during a fall, prolonged sitting on a hard or narrow surface, degenerative joint changes, or vaginal childbirth.

What is the function of the sacral nerve?

The sacral plexus (plexus sacralis) is a nerve plexus that provides motor and sensory nerves for the posterior thigh, most of the lower leg, the entire foot, and part of the pelvis (see the following image).

What causes sacrococcygeal disorder?

The cause of sacrococcygeal teratomas is unknown. Sacrococcygeal teratomas are germ cell tumors. Germ cells are the cells that develop into the embryo and later on become the cells that make up the reproductive system of men and women. Most germ cell tumors occur in the testes or ovaries (gonads) or the lower back.

Where are the nerves in the sacrococcygeal joint located?

The sacrococcygeal joint is innervated from the sacral spinal nerves S4-S5 and the coccygeal spinal nerve Co.

What is the anatomy of the sacrococcygeal cornual region?

Reference texts describe an intercornual ligament connecting these structures. The aim of this study was to investigate the anatomy of this region, which may be relevant to unexplained cases of coccygeal pain (coccydynia) and local nerve blocks.

What’s the difference between coccygodynia and sacrococcygeal pain?

True coccygodynia consists of pain arising from the sacrococcygeal joint, whereas pseudococcygodynia consists of pain referred to but not arising from the cocc … Sacrococcygeal pain can arise from the sacrococcygeal joint, from contiguous structures sharing the same innervation, or from distant sites.

Where does the coccygeal nerve exit the sacral hiatus?

The Sacrum, Sacroiliac Joint, and Coccyx. Gregory D. Cramer, Chae-Song Ro, in Clinical Anatomy of the Spine, Spinal Cord, and Ans (Third Edition), 2014. Both the left and the right S5 nerves and the coccygeal nerve of each side exit the sacral hiatus just medial to the sacral cornua of the same side.
