The triceps brachii, also known as ‘triceps’, are one of the most popular muscles in the body. It is almost as popular as the rectus abdominis due to the amount the muscle is worked. This muscle is popular because it is one of the muscles of the upper arm that tends to bulge out in weightlifters or people who work out regularly.
In this article, we will be discussing the anatomy of the triceps brachii muscle, the various functions of this critical muscle and what to do to prevent injuries to this muscle.
Anatomy of Triceps Brachii
The tricep is a large muscle in the upper arm of the body and is made up of three heads namely:
- Long head – Which originates from around the scapular (also known as the wing bone).
- Medial head – Which has its origin around the humerus bone.
- Lateral head – Which also originated from around the humerus bone.
The three heads of the triceps brachii all come together to form a thick tendon. The nerve supply of this muscle is from the radial nerve while the blood supply is from the branches of the deep brachial artery. The blood supply allows nutrients and oxygen to be transferred to this particular muscle. This will enable it to perform its functions optimally.
