Today, we'll explore the Triceps Brachii, commonly known as the triceps, a muscle located in the upper arm that plays a crucial role in elbow extension and shoulder movements.
Have you ever wondered which muscle is responsible for straightening your arm? The triceps brachii is the primary muscle involved in this action!
📌 What Is the Triceps Brachii? Where Is It Located?
The triceps brachii is a large muscle on the back of the upper arm, consisting of three heads: the long head, lateral head, and medial head.
✅ Anatomical Features of the Triceps Brachii
- Location: Posterior aspect of the upper arm.
- Origins:
- Long Head: Infraglenoid tubercle of the scapula.
- Lateral Head: Posterior surface of the humerus, superior to the radial groove.
- Medial Head: Posterior surface of the humerus, inferior to the radial groove.
- Insertion: Olecranon process of the ulna.
- Innervation: Radial nerve (C6–C8).
The triceps brachii is responsible for extending the elbow joint and also assists in shoulder movements.
📌 Functions of the Triceps Brachii: Why Is It Important?
The triceps brachii performs several key functions:
