Obturator nerve

Obturator Nerve

The Obturator Nerve is a significant nerve in the human body that originates from the Lumbar Plexus. It is responsible for the sensory and motor supply to parts of the lower limbs, mainly the medial aspect of the thigh.

Anatomy

The Obturator Nerve is formed from the anterior divisions of the second, third, and fourth Lumbar Nerves. It descends through the fibers of the Psoas Major Muscle, and emerges from its medial border to pass down into the pelvis, just above the pelvic brim.

Function

The Obturator Nerve is responsible for the sensory innervation of the skin of the medial aspect of the thigh. It also provides motor innervation to the adductor muscles of the lower limb, which include the Adductor Longus, Adductor Brevis, Adductor Magnus, Gracilis, and Obturator Externus.

Clinical Significance

Damage to the Obturator Nerve can result in a condition known as Obturator Nerve Entrapment. This condition is characterized by pain, weakness, and sensory loss in the distribution of the Obturator Nerve. It is often caused by trauma, surgery, or prolonged compression of the nerve.
