* These muscles (and subscapularis) form the rotator cuff which is a critical stabilizing element for the glenohumeral joint (shoulder joint). Thus, one action for each of these muscles is to stabilize the shoulder joint. Examine the rotator cuff muscles in the cadaver and see if you can determine where the tendons incompletely surround the head of the humerus. What clinical significance does this have?

Flexors / ExtensorsQuestion:Muscle or muscles that answers the question:Contracting both heads of this muscle (deep to the platysma) causes flexion of the head.Contraction this muscle would cause the vertebral column to flex forward—used to do “sit-ups”.As a group, these muscles extend (straighten the angle of) the knee.
