The biceps brachii has two heads (long and short) and is located on the anterior side of the upper arm. The brachialis is deep to the biceps brachii and also contributes to forearm flexion.
2. The triceps brachii has three heads (long, lateral, and medial) and is located on the posterior side of the upper arm. Its main function is to extend the forearm at the elbow joint, which is relevant for forelimb extension in both pigs and humans.
