Question: what is the difference between your bicep brachii and your bicep femoris?
Answer: The tendon of this muscle is attached to the inner protrusion near the head of the radius, a bone of the forearm. The biceps brachii bends the forearm toward the upper arm and is thus used in lifting and pulling movements. ... The biceps femoris is one of the hamstring muscles at the back of the thigh.
