Sacral ganglia

From WikiMD's Wellness Encyclopedia

(Redirected from Sacral ganglion)

Sacral ganglia are a group of nerve cell bodies, also known as ganglion, located in the sacral region of the spinal cord. They are part of the autonomic nervous system, specifically the parasympathetic nervous system, and play a crucial role in transmitting signals from the brain to various parts of the body.

Etymology[edit | edit source]

The term "sacral" is derived from the Latin word "sacrum", which means "sacred". This is because the sacrum was considered sacred by the ancient Romans. The term "ganglia" is derived from the Greek word "ganglion", which means "knot" or "swelling", referring to the appearance of these structures.

Structure and Function[edit | edit source]

The sacral ganglia are paired structures located on either side of the middle line of the sacrum, the triangular bone at the base of the spine. They are part of the spinal ganglia, which also include the cervical ganglia, thoracic ganglia, and lumbar ganglia.

The sacral ganglia contain the cell bodies of sensory neurons, which transmit sensory information from the periphery to the central nervous system. They also contain the cell bodies of motor neurons, which transmit motor commands from the central nervous system to the periphery.

The sacral ganglia are involved in various bodily functions, including bladder control, sexual function, and certain reflexes. They receive input from the sacral nerves, which are part of the spinal nerves.

Clinical Significance[edit | edit source]

Damage or disease affecting the sacral ganglia can lead to various neurological disorders, such as neuropathic pain, bladder dysfunction, and sexual dysfunction. Treatment options for these conditions may include medication, physical therapy, and in some cases, surgery.
