MUSCULUS ULNARIS EXTERNUS Meaning and
Definition
-
Musculus ulnaris externus, also known as the external ulnar muscle, is a term commonly used in anatomical contexts to describe a muscle located in the human forearm. The Latin term "musculus" refers to a muscle, while "ulnaris" pertains to the ulna bone, which is one of the two long bones in the forearm. "Externus" indicates that it is situated on the outside or external aspect of the forearm.
The musculus ulnaris externus is a relatively small muscle that originates from the lateral epicondyle, a bony prominence on the outer side of the elbow, and inserts onto the ulnar aspect of the posterior border of the ulna bone. Its primary function is to flex the forearm at the elbow joint and to contribute to the supination of the forearm, which is the rotation of the forearm to allow the palm to face upward.
This muscle works in coordination with other muscles in the forearm to carry out various movements of the upper limb, such as those involved in gripping, throwing, and lifting objects. The precise action of the musculus ulnaris externus can vary depending on the specific position and direction of the forearm during a particular movement.
