What are the two muscles in the bicep?
Two muscles lie underneath the biceps brachii. These are the coracobrachialis muscle, which like the biceps attaches to the coracoid process of the scapula, and the brachialis muscle which connects to the ulna and along the mid-shaft of the humerus.
Where are your triceps and biceps?
The biceps and triceps make up a large majority of your arm musculature.
