The muscles are largely involved with flexion and supination. [2] The superficial muscles have their origin on the common flexor tendon. [2] The ulnar nerve and artery are also contained within this compartment. [2] The flexor digitorum superficialis lies in between the other four muscles of the superficial group and the three muscles of the ...
The anterior compartment of the leg is supplied by the deep fibular nerve (deep peroneal nerve), a branch of the common fibular nerve. The nerve contains axons from the L4, L5, and S1 spinal nerves. Blood for the compartment is supplied by the anterior tibial artery, which runs between the tibialis anterior and extensor digitorum longus muscles.
This muscle originates from the medial epicondyle of the humerus as part of the common flexor tendon. It runs just laterally of flexor digitorum superficialis and inserts on the anterior aspect of the base of the second metacarpal , and has small slips to both the third metacarpal and trapezium tuberosity.
The muscle's superficial head arises from the distal edge of the flexor retinaculum and the tubercle of the trapezium, the most lateral bone in the distal row of carpal bones. [1] It passes along the radial side of the tendon of the flexor pollicis longus. The deeper (and medial) head "varies in size and may be absent."
The nerve of the anterior compartment of thigh is the femoral nerve. [2] Innervation for the quadriceps muscles come from the posterior division of the femoral nerve, while the anterior division (which contains cutaneous as well as muscular components) gives a lateral and a medial branch, the second being responsible for the innervation of the sartorius muscle.

The patellar tendon is a strong, flat ligament, which originates on the apex of the patella distally and adjoining margins of the patella and the rough depression on its posterior surface; below, it inserts on the tuberosity of the tibia; its superficial fibers are continuous over the front of the patella with those of the tendon of the quadriceps femoris.

The tibialis anterior muscle is the most medial muscle of the anterior compartment of the leg. [1] [better source needed] The muscle ends in a tendon which is apparent on the anteriomedial dorsal aspect of the foot close to the ankle. [citation needed] Its tendon is ensheathed in a synovial sheath.
