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 deep group.
The brachioradialis, flexor of the elbow, is unusual in that it is located in the posterior compartment, but it is actually a muscle of flexor / anterior compartment of the forearm. The anconeus , assisting in extension of the elbow joint, is by some considered part of the posterior compartment of the arm.
The tongue is a composite muscle made up of various components like longitudinal, transverse, horizontal muscles with different parts innervated having different nerve supply. Digastric muscle: Its anterior belly is supplied by mylohyoid nerve (a branch of trigeminal nerve). The posterior belly is supplied by the facial nerve.
In anatomy, flexor is a muscle that contracts to perform flexion (from the Latin verb flectere, to bend), [1] a movement that decreases the angle between the bones converging at a joint. For example, one's elbow joint flexes when one brings their hand closer to the shoulder , thus decreasing the angle between the upper arm and the forearm .
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.
The anterior interosseous nerve (a branch of the median nerve) and the anterior interosseous artery and vein pass downward on the front of the interosseous membrane between the flexor pollicis longus and flexor digitorum profundus. [4] Injuries to tendons are particularly difficult to recover from due to the limited blood supply they receive.
Anterior compartment: Tibialis anterior; Extensor hallucis longus; Extensor digitorum longus; Peroneus tertius; Deep fibular (peroneal) nerve and anterior tibial vessels: Lateral compartment: Fibularis longus; Fibularis brevis; Superficial fibular (peroneal) nerve and fibular artery: Deep posterior compartment: Tibialis posterior; Flexor ...
