  Reference.com/Encyclopedia/Biceps brachii muscle
The term biceps brachii is a Latin phrase meaning "two-headed [muscle] of the arm", in reference to the fact that the muscle consists of two bundles each with its own origin but with a common insertion point near the elbow.
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 the humerus.
One of the main functions of the biceps is to, along with the supinator muscle, aid in supination of the forearm, which refers to the allowing the forearm, and subsequently, the palm, to be rotated or moved toward the anatomical position, the resulting hand position not dissimilar to that of the biceps curl.

The triceps brachii muscle is a large three-headed skeletal muscle found in humans.
The triceps brachii serves to extend the elbow, therefore it is an extensor muscle.
The biarticulate long head of the triceps brachii enters passive insufficiency through the completion of elbow flexion when the shoulders are more flexed and abducted or through the completion of shoulder flexion and abduction when the elbows are more flexed.

 USA Gymnastics Online: Technique: Muscular Force and Biomechanical Implications
The biceps brachii muscle acts as one of the primary movers, with elbow flexion occurring around the mediolateral axis in the sagittal plane.
Consequently, the majority of the resultant force produced by the biceps brachii in frame B is now directed toward moving the lower arm segment at the elbow joint; a smaller portion is focused on stabilizing the joint.
The closer the resultant angle of muscle insertion is to 90 degrees, the larger the angular vector for moving a bony segment, and conversely the smaller the stabilizing force vector for improving joint integrity (Kreighbaum and Barthels, 1996).

Rectus means "straight," and rectus muscles are parallel muscles whose fibers generally run along the long axis of the body.

Most skeletal muscles of the body are a mixture of all three types of skeletal muscle fibers, but their proportion varies depending on the usual action of the muscle.
Muscles of the shoulders and arms are not constantly active but are used intermittently, usually for short periods of time, to produce large amounts of tension such as in lifting and throwing.

There is still disagreement regarding the functions of the long head of the biceps brachii muscle.
Pure traction overload tendinitis of the biceps tendon has not been identified, although few investigators have performed actual biopsy studies of the bicipital tendon at the time of treatment.4 Some surgeons even regard it as a vestigial structure and when symptomatic, have excised it or anchored the tendon to prevent it from moving (tenodesis).
More recently, Levy, et al.,1 demonstrated that the long head of the biceps was not active in isolated shoulder motion when the elbow and forearm were controlled, and that bicipital function correlated with motion at the elbow, not the shoulder.

An EMG or electromyographic recording of muscle activity is often done to determine the extent of muscle involvement for a particular movement.
For example, in comparing two functionally distinct regions of the pectoralis major muscle (i.e., clavicular head and sternocostal head), they found that the clavicular head of the pec major (the part attached to the collarbone or clavicle) was more active during a narrow grip vs. wide grip, esp. during the flat and incline bench press.
Further evidence for the functional differentiation within the biceps muscle is magnetic resonance imaging which demonstrate that a standing bilateral dumbell curl with your palms up (supinated) hits the medial or short head of the biceps brachii muscle more so than the lateral or long head.
