A. Describe the movements of transverse adduction and flexion for the pectoralis major and biceps brachii muscles.
Added by Eric J.
Step 1
When the pectoralis major muscle contracts, it pulls the arm towards the midline of the body, causing transverse adduction. The biceps brachii muscle also assists in this movement by flexing the elbow joint. Flexion refers to the movement of bending a joint, such Show more…
