What does triceps mean in anatomy?

The triceps, also triceps brachii (Latin for “three-headed muscle of the arm”), is a large muscle on the back of the upper limb of many vertebrates. It consists of 3 parts: the medial, lateral, and long head. It is the muscle principally responsible for extension of the elbow joint (straightening of the arm).

What are the triceps?

What are the 3 heads of the triceps?

There are three muscles on the upper arm that are parallel to the long axis of the humerus, the biceps brachii, the brachialis, and the triceps brachii. … The biceps brachii has two synergist muscles that assist it in flexing the forearm. Both are found on the anterior side of the arm and forearm.

Are biceps stronger than triceps?

The triceps are a larger muscle group than the biceps, which means they have more potential to grow. The third group is the brachialis, an upper arm muscle that runs under the biceps. It’s really only visible when looking at the arms from the side, but will make your arms appear much larger when viewed this way.

What are the biceps and triceps an example of?
