The _____________________ is the Prime Elbow Flexor

Question

The _____________________ is the prime elbow flexor.
A)Biceps femoris
B)Biceps brachii
C)Triceps brachii
D)Flexor digitorum

Accepted Answer

The biceps brachii muscle is the prime elbow flexor, as it crosses the elbow joint and has the primary function of flexing the forearm. The biceps femoris is a muscle in the thigh that functions to flex the knee and extend the hip. The triceps brachii is the prime elbow extensor, responsible for extending the forearm. The flexor digitorum muscle is a wrist and finger flexor, not an elbow flexor.
