Sacral plexus
Sacral Plexus
The Sacral Plexus (pronunciation: SAK-rəl PLEK-səs) is a significant part of the Peripheral Nervous System that supplies nerves to the lower limb. It is formed by the lumbosacral trunk, the anterior division of the first sacral nerve, and portions of the second and third sacral nerves.
Etymology
The term "Sacral Plexus" is derived from the Latin word "sacrum," which means sacred bone, and the Latin word "plexus," which means braid. This is due to the complex interweaving of nerves that form this structure.
Structure
The Sacral Plexus is formed by the union of the lumbosacral trunk and the anterior divisions of the first, second, and third sacral nerves. It is located in the pelvis, and its nerves extend to the lower limb.
Function
The Sacral Plexus provides motor and sensory nerves for the posterior thigh, most of the lower leg, the entire foot, and part of the pelvis. It is responsible for innervating the muscles and skin of these areas.
