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 3 parts: the medial, lateral, and long head. [1] It is the muscle principally responsible for extension of the elbow joint (straightening of the arm). Publication types Review The triceps brachii (TB) is the only muscle that lies along the posterior humerus, and its role in elbow extension has been the topic of investigation for many decades. The TB research has also included subjects such as strength training, effects of aging, training adaptions, etc. The purpose of thi … The upper extremity or arm is a functional unit of the upper body. It consists of three sections, the upper arm, forearm, and hand. It extends from the shoulder joint to the fingers and contains 30 bones. It also consists of many nerves, blood vessels (arteries and veins), and muscles. The nerves of the arm are supplied by one of the two major nerve plexus of the human body, the brachial plexus. Triceps brachii: Commonly called the triceps, this muscle runs on the posterior side of the humerus. It is a large thick muscle that may look like a horseshoe and includes three heads: long The triceps muscle is responsible for the extension of the elbow joint and straightening of the arm, and it also plays a significant role in the stability and strength of the shoulder. The triceps' position and function are critical for sustaining upper body strength and facilitating coordinated arm movements. Triceps Exercises It provides muscle function for most upper arm muscles and feeling to much of the forearm. The musculocutaneous nerve is an important arm nerve. It provides muscle function for most upper arm muscles and feeling to much of the forearm. The triceps brachii is in the posterior (back) compartment while the rest are in the anterior (front The triceps, or triceps brachii, is Latin for the three-head muscle of the arm made up of three separate muscles — long, medial, and lateral head — with different origins, but they all converge in the same place on the elbow. The triceps long head is the biggest of the three muscles and originates at the infraglenoid tubercle of the scapula. fxvmGyL.
