The humerous is the upper arm bone. Its primary function is to support the arm muscles and allow the arm to move.
The organ in the arm that is not necessary is the palmaris longus muscle. It is a thin muscle located on the palm side of the forearm and is absent in about 14% of the population. Its absence does not affect normal arm function.
The main function of the musculocutaneous nerve is to innervate the muscles in the anterior compartment of the arm, including the biceps brachii muscle. It also provides sensory innervation to the lateral aspect of the forearm.
The supraspinatus muscle is one of the four muscles of the rotator cuff in the shoulder. Its main function is to assist in the abduction (lifting away from the body) of the arm at the shoulder joint. It also helps to stabilize the shoulder joint during arm movements.
It acts as a strut to keep the scapula in place so the arm can hang freely.

Squids have four pairs of arms and a pair of tentacles. The tentacles are longer than the arms. The tentacles perform the function of grabbing prey and holding on to it. There are hooks on the arms as well as the tentacles of squids but the ones on the tentacles can swivel while those on the arm cannot. These help squids hold on to their prey better while the prey tries to escpe. Suckers are present on both the arms as well as the tentacles of squids, though the ones on the arms are bigger.
