In this article we will discuss about Palmaris longus muscle. So let’s get started.
It originates from the medial epicondyle of humerus and also from the adjacent intermuscular septa and from antebrachial fascia. It passes over the flexor retinaculum and gets inserted into the central part of flexor retinaculum and palmar aponeurosis. It is innervated by median nerve and blood supply is through the ulnar artery. It’s primary action is flexion of the wrist. Clinically this tendon is used as tendon grafts.
