In order to create elbow flexion the bicep brachii is the 16. which attaches to
the lower arm and moves in closer to the shoulder. the tricep or 17. has to
relax and elongate in order for the bicep to contract. the lower arm is stabilized by the
brachialis. the muscle that stabilizes is known as a(n) 18. the point where the
bicep brachii attaches to the shoulder is called the point of 19. because it does
not move during contract and is proximal to the body. conversely, the point of 20.
is distal and does move during contraction.
