Triceps.

Quadriceps' units and sartorius
A muscle having three heads; specif., the great extensor of the forearm, arising by three heads and inserted into the olecranon at the elbow.
Triceps bachii is the scientific name of the muscle given to the more popularly called triceps muscle. Tri means three. Ceps means heads. It has got three heads. Brachii means related to your brachium or the arm.
The triceps brachii is attached in three places. It has three heads, as its name indicates.
"Tri" is the Latin for three. "Ceps" means head. The triceps muscle, found on the back part of the upper arm, has three "heads" or spots where it attaches to the bone. The triceps is the opposing muscle for the biceps, which has "two-heads."
Three main parts of the forelimb for a cat include the humerus, the radius, and the Ulna. This is the same anatomy as large cats.
Antagonists of the biceps are triceps (the three head muscle). Biceps flex and triceps extend.
Triceps Brachii - it is the only muscle fleshing out the posterior humerus; its three heads arise from the shoulder girdle and proximal humerus, and it inserts into the olecranon process of the ulna. It is a powerful prime mover of elbow extension.triceps brachii
The muscle of the thigh are classified into three groups, anterior group, posterior group, and interior or adductors group. There are four muscle on the anterior group - quadriceps femoris- and their function is to extend the knee or extend the thigh depend on what part of the muscle don't move. Those muscle are the rectus femorarlis, vastu intermedius, vastu medialis, and vastus lateralis. The muscle that flex the knee are located on the back of the thigh and form the posterior group. They are the biceps femoris, semitendinousus, and the semimembranosus, better known as Hamstring.
It tells you the number of origins. "When biceps, triceps, or quadriceps forms part of a muscle's name, you can assume that the muscle has two, three, or four origins, respectively. For example, the biceps brachii muscle of the arm has two origins, or heads."- Human Anatomy & Physiology. Eighth Edition. Elaine N. Marieb page 321

The triceps brachii muscle is the primary extensor of the elbow, also known as the olecranon. To clarify, it is the elbow that can also be known as the olecranon. The olecranon is the posterior process of the ulna. The triceps brachii muscle has three heads (hence TRI-, meaning three) - the long head which originates from the infraglenoid tubercle of the scapula, and the short and lateral heads which originate from the posterior surface of the humerus. The three meet and join to the olecranon of the ulna. When this muscle contracts, it pulls the olecranon in the direction of the shoulder - thus extending the forearm at the elbow joint. The triceps brachii muscle is innervated by the radial nerve, originating from spinal levels C6 and C8, but primarily C7.
