Triceps.
The muscle that has three heads, can extend the forelimb, and is found in both pigs and humans is the triceps brachii. It consists of the long head, lateral head, and medial head, which work together to extend the elbow joint. This muscle plays a crucial role in arm movement and stability.
The muscle of the arm with three heads or points of origin is the triceps brachii.
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.

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
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.
The triceps muscle is located on the back of the upper arm and has three heads, while the biceps muscle is located on the front of the upper arm and has two heads. The triceps muscle is responsible for extending the arm, while the biceps muscle is responsible for flexing the arm.
The scientific name of the triceps muscle is "triceps brachii." It is located in the upper arm and is responsible for extending the elbow. The name "triceps" means "three heads," referring to its three distinct muscle heads: the long head, lateral head, and medial head.
Antagonists of the biceps are triceps (the three head muscle). Biceps flex and triceps extend.
