What muscles make up the elbow joint?
- Biceps brachii: upper arm muscle enabling flexion of the arm.
- Triceps brachii: muscle in the back of the upper arm that extends the arm and fixes the elbow during fine movements.
- Brachialis: upper arm muscle beneath the biceps which flexes the elbow towards the body.
What muscles cross the Humeroulnar joint?
The humeroulnar articulation engages primarily in flexion and extension in the sagittal plane, with flexion to 150º and extension to 0º in the neutral position. The biceps brachii, brachialis, brachioradialis, and pronator teres all flex the elbow. The triceps brachii and anconeus serve to extend the elbow.
