Plexus coccygeus

Plexus coccygeus is a network of nerves located in the pelvis. It is also known as the coccygeal plexus and is part of the larger sacral plexus. The plexus coccygeus is responsible for the innervation of the coccyx and surrounding areas.

Anatomy

The plexus coccygeus is formed by the ventral rami of the coccygeal nerve and the fifth sacral nerve. It is located in the pelvis, near the sacrum and coccyx. The plexus coccygeus is connected to the sacral plexus, which is a larger network of nerves that provides motor and sensory innervation to the pelvis and lower limbs.

Function

The primary function of the plexus coccygeus is to provide sensory and motor innervation to the coccyx and surrounding areas. This includes the skin over the coccyx, as well as some of the muscles in the pelvic floor. The plexus coccygeus also plays a role in the functioning of the pelvic organs, including the rectum and bladder.

Clinical significance

Damage or injury to the plexus coccygeus can result in a variety of symptoms, including pain, numbness, and weakness in the coccyx and surrounding areas. This can be caused by a variety of factors, including trauma, surgery, or certain medical conditions. Treatment for plexus coccygeus injury typically involves managing the symptoms and addressing the underlying cause of the injury.
