How Do You Spell SUPINATOR BREVIS AND LONGUS?

1. The supinator brevis and longus are two muscles located in the forearm that play a vital role in the movement of the forearm and hand.

   The supinator brevis is a short muscle that originates from the lateral epicondyle of the humerus, a bony prominence on the outer side of the elbow, and inserts into the posterior surface of the radius bone. Its function is to supinate the forearm, which means to turn the palm of the hand upward or to face forward. This muscle works in coordination with other muscles to allow the rotational movement of the forearm.

   The supinator longus is a longer muscle that originates from the lateral part of the humerus, above the common origin of the supinator brevis, and ends in the posterior surface of the ulna bone. Its primary function is to assist in supinating the forearm, working synergistically with the supinator brevis. The supinator longus contributes to the rotational movement of the forearm, allowing us to turn our palm upward or forward.

   Overall, the supinator brevis and longus muscles are vital for the rotational movement of the forearm and the positioning of the hand. Dysfunction or injury to these muscles may result in limited or painful supination of the forearm, compromising everyday activities that involve hand and arm movements.
