Triceps brachii muscle

This video tutorial covers the triceps brachii muscle, detailing its location, composition, origins, insertions, function, and innervation. The triceps brachii, known as the 'applause muscle,' is located in the posterior upper arm and consists of three heads: long, medial, and lateral. Each head has a distinct origin but converges into a tendon at the elbow. The muscle extends the arm and is innervated by the radial nerve. The video concludes with a call to explore more resources on Kenhub.
