The obturator nerve is responsible for the sensory innervation of the skin of the medial aspect of the thigh. The nerve is also responsible for the motor innervation of the adductor muscles of the lower limb (external obturator, [4] adductor longus, adductor brevis, adductor magnus, gracilis) and the pectineus (inconstant).
The nerve to obturator internus (also known as the obturator internus nerve [citation needed]) is a mixed (sensory and motor) [1] nerve providing motor innervation to the obturator internus muscle and gemellus superior muscle, [2] [1] and sensory innervation to the hip joint. [1] It is a branch of the sacral plexus. It is one of the group of ...
The obturator nerve is the primary nerve supplying this compartment. The obturator artery is the blood supply to the medial thigh. The muscles in the compartment are: gracilis; adductor longus; adductor brevis; adductor magnus; The obturator externus muscle is sometimes considered part of this group, [1] [2] [3] and sometimes excluded.

The internal obturator muscle or obturator internus muscle originates on the medial surface of the obturator membrane, the ischium near the membrane, and the rim of the pubis. It exits the pelvic cavity through the lesser sciatic foramen. The internal obturator is situated partly within the lesser pelvis, and partly at the back of the hip-joint.
All muscles in the lateral rotator group originate from the hip bone and insert on to the upper extremity of the femur. The muscles are innervated by the sacral plexus ( L4 - S2 ), except the obturator externus muscle , which is innervated by the lumbar plexus .
The obturator nerve innervates the gracilis muscle via the lumbar spinal vertebrae. ... the nerve also enters. Gracilis muscle is widely used in reconstructive ...
The posterior branch of the obturator nerve pierces the anterior part of the obturator externus, and supplies this muscle; it then passes behind the adductor brevis on the front of the adductor magnus, where it divides into numerous muscular branches which are distributed to the adductor magnus and the adductor brevis.

Hilton's law, espoused by John Hilton in a series of medical lectures given in 1860–1862, [1] is the observation that in the study of anatomy, the nerve supplying the muscles extending directly across and acting at a given joint not only supplies the muscle, but also innervates the joint and the skin overlying the muscle.
