What is the name of the tricep muscles?

Answer 1

The tricpes brachii muscle is one muscle. It is an extensor muscle, meaning that it opens, or extends the arm from the shoulder (as opposed to the bicpes, which is a flexor muscle, that closes the arm.)

Answer 2

triceps brachii
the scientific, or latin name for the triceps muscle in humans is the "triceps brachii". triceps meaning (three heads) and brachii (meaning arm). this muscle has three connecting points (or heads) to hard tissue joints and runs along the ventral aspect (underneath) of the upper arm, from the superior aspect of the elbow to the inferior aspect of the shoulder girdle. when understanding the dorsal-vs-ventral relationship, begin the view of the arm with the palms up. to better understand its location, look at the biceps brachii (common name "biceps") and then look on the opposite side of the same region of the arm. the opposing musculature to the biceps brachii is the triceps brachii.

the triceps brachii in humans is not to be confused with the triceps femoris, which is found in the anura order (aka frogs and toads). in humans, triceps femoris musculature does not exist.
