tricepsejä

Triceps are a group of three muscles located at the back of the upper arm, named for their three-headed structure. They are one of the largest muscle groups in the human body and play a crucial role in elbow extension and stabilization of the shoulder joint. The triceps muscles are innervated by the radial nerve and are responsible for various movements, including extending the elbow, straightening the arm, and assisting in overhead movements.

The triceps muscles are composed of three distinct heads: the long head, the lateral head, and the medial head. Each head originates from different points on the humerus and inserts at the olecranon process of the ulna. The long head originates from the infraglenoid tubercle of the scapula, the lateral head from the posterior humerus, and the medial head from the posterior humerus and the supracondylar ridge.

The triceps muscles are essential for activities such as pushing, throwing, and lifting. They are also involved in maintaining proper posture and stability of the shoulder and elbow joints. Proper triceps function is vital for overall upper body strength and mobility.

Exercises that target the triceps muscles include push-ups, tricep dips, overhead extensions, and various weightlifting movements. Strengthening the triceps can help improve athletic performance, reduce the risk of injury, and enhance overall upper body strength. However, it is important to perform these exercises with proper form and gradually increase the weight or resistance to avoid injury and ensure muscle growth.
