Muscles in the Elbow

Elbow anatomy

Elbow anatomy

The elbow is a joint (point of articulation that allows movement) comprised of three main bones: the humerus (upper arm), radius, and ulna.  The elbow joint and articulation between the radius and ulna provide a variety of upper extremity motions including:

    • Flexion – Bending elbow 
    • Extension – Straightening elbow 
    • Pronation – Turning forearm palm down
    • Supination – Turning forearm palm up

These upper extremity movement can occur via the attachment of muscles that cross the elbow joint. All muscles have sites of two mains points of attachment known as the origin and insertion.  The origin is typically proximal (closest) to the trunk of the body and has limited motion, whereas the insertion tends to be distal (farther away from the body) and has more movement 

Primary Muscles of the Elbow

Biceps Brachii 

The biceps brachii crosses both the elbow and shoulder joint – however, this muscle’s primary function is elbow flexion.  This muscle secondary activation is to assist in shoulder flexion

Triceps Brachii 

The triceps brachii, just like the biceps brachii crosses both the elbow and shoulder joint as well but is located along the posterior aspect of the arm. This muscle’s primary function is elbow extension but also helps assist extension of the shoulder

Brachioradialis 

The brachioradialis muscle is located from the elbow and inserts into the forearm area. This muscle helps assist with the biceps brachii to flex the elbow

Brachialis 

The brachialis muscle is located at the distal half of the humerus and inserts into the forearm. This muscle performs elbow flexion and is considered the prime flexor of the forearm at the elbow joint

Anconeus

The anconeus is a smaller muscle, triangular in shape. This muscle is located along the outside of the elbow, lateral epicondyle, and inserts into the posterior aspect of the elbow (ulna bone). Muscle serves to help the elbow extend 

Supinator   

The supinator is a spiral muscle located along the posterior aspect of the forearm. This muscle performs supination of the forearm/elbow. Supination of the elbow is when the palm is facing upwards. An example of when using supination would be turning a screwdriver or turning a key
