Coccygeal plexus

Coccygeal Plexus

The coccygeal plexus is a network of nerve fibers located in the lower part of the spinal cord, specifically in the sacral region. It is formed by the ventral rami of the coccygeal nerve and the fifth sacral nerve. The coccygeal plexus is responsible for the innervation of the skin over the coccyx and a part of the anus.

Anatomy

The coccygeal plexus is formed by the ventral rami of the coccygeal nerve and the fifth sacral nerve. These nerves branch out to form a network that provides sensory and motor innervation to the skin over the coccyx and a part of the anus. The coccygeal plexus is located in the pelvic cavity, near the sacrum and coccyx.

Function

The primary function of the coccygeal plexus is to provide sensory and motor innervation to the skin over the coccyx and a part of the anus. This includes the perception of pain, temperature, and touch in these areas. The coccygeal plexus also plays a role in the control of defecation and micturition.

Clinical Significance

Damage or injury to the coccygeal plexus can result in coccydynia, a condition characterized by pain in the coccyx region. This can be caused by trauma, childbirth, or prolonged sitting. Treatment options for coccydynia include pain management, physical therapy, and in severe cases, surgical removal of the coccyx.
