The first branch of the median nerve is to the pronator teres muscle, then the flexor carpi radialis, the palmaris longus and the flexor digitorum superficialis.
Nerve conduction studies may be normal or show pronator quadratus latency.
At the cubital fossa, this nerve is deep to the pronator teres muscle and is the most medial structure in the fossa.
In the forearm, this action is performed by pronator quadratus and pronator teres muscle.
It is assisted in this action by pronator quadratus.
More recent literature collectively diagnose median nerve palsy occurring from the elbow to the forearm as pronator teres syndrome.
The nerve enters the cubital fossa medial to the brachialis tendon and passes between the two heads of the pronator teres.
The middle third of the body attaches to the extensor ossis metacarpi pollicis, extensor primi internodii pollicis, and the pronator teres muscles.
