Several muscles that control the elbow joint are actually located in the forearm. Key muscles involved in elbow function that reside primarily in the forearm include the brachioradialis, the pronator teres, and the supinator. These muscles assist in flexion, pronation, and supination of the forearm, respectively.
-
Brachioradialis: Primarily located in the forearm, it flexes the elbow, especially when the forearm is pronated or supinated.
-
Pronator Teres: Located primarily in the forearm, it assists in pronating the forearm.
-
Supinator: Located in the forearm, it supinates the forearm.
In addition to the forearm muscles, other muscles, while located in the upper arm, have tendons that cross the elbow joint and are therefore crucial for elbow movement. Examples of these include the biceps brachii, brachialis (though often considered an upper arm muscle, it's very close to the elbow), and triceps brachii. However, since the question specifically asks about muscles in the forearm at the elbow, the primary focus is on the brachioradialis, pronator teres, and supinator.
