Extensors of the Elbow Include (The)________

Question

Extensors of the elbow include (the)________.
A) brachioradialis and brachialis muscles
B) coracobrachialis and brachioradialis muscles
C) triceps brachii and anconeus muscles
D) deltoid and supinator muscles
E) palmaris longus and brachioradialis muscles

Accepted Answer

The triceps brachii and anconeus muscles are the main extensors of the elbow joint. The brachioradialis and brachialis muscles are flexors of the elbow joint, while the coracobrachialis is an adductor and the deltoid and supinator muscles are not directly involved in elbow extension. The palmaris longus muscle is also a flexor of the wrist, not the elbow.
