Which tendon is frequently absent in the upper limb?
High-Yield Explanation
The palmaris longus may not always be present. It has a sho belly and long tendon. It originates from the medial epicondyle of the humerus. Distally, it passes over the flexor retinaculum with which its fibres mingle and is attached to the palmar aponeurosis.
