Bipennate/ fusiform
Examine the fascicle arrangement of the fusiform muscle and the bipennate muscle. The biceps brachii is a fusiform muscle, and the rectus femoris is a bipennate muscle. The _______ muscle will be powerful, but have more of a limited range of motion than the ______ muscle.
The insertion will be pulled toward the origin
If the biceps brachii contracts, which of the following events will occur?
B, C, D
In addition to the subscapularis, three other muscles form the rotator cuff- a group of four deep muscles that strengthen and stabilize the shoulder. The tendons merge to nearly encircle the shoulder joint, a joint which provides the body's greatest range of motion.
