The triceps, or 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 three parts: the medial, lateral, and long head. [1] It is the muscle principally responsible for extension of the elbow joint (straightening of the arm).
Muscles contributing to function are all flexion (biceps brachii, brachialis, and brachioradialis) and extension muscles (triceps and anconeus). In humans, the main task of the elbow is to properly place the hand in space by shortening and lengthening the upper limb.
The antagonistic pair of biceps and triceps working to flex the elbow. Antagonist and agonist muscles often occur in pairs, called antagonistic pairs. As one muscle contracts, the other relaxes. An example of an antagonistic pair is the biceps and triceps; to contract, the triceps relaxes while the biceps contracts to lift the arm.
Triceps muscles anatomy The triceps (also known as the triceps brachii) is the muscle behind the arm, opposite of the bicep — and they get their name due to being made up of three different muscles.
These triceps exercises target the muscles that stabilize the shoulder and support your upper half on rides.
The articularis cubiti muscle is a muscle of the elbow. It is considered by some sources to be a part of the triceps brachii muscle. It is also known as the "subanconeus muscle", for its relationship to the anconeus muscle. [1] It is classified as a muscle of the posterior brachium.
The anconeus muscle (or anconaeus/anconæus) is a small muscle on the posterior aspect of the elbow joint. Some consider anconeus to be a continuation of the triceps brachii muscle. [1] [2] [3] Some sources consider it to be part of the posterior compartment of the arm, [4] while others consider it part of the posterior compartment of the ...
