Where does the triceps originate and attach?

The triceps is one of the important muscle groups in our body. It is mainly located in the arm and is related to the strength of the arm. We use the triceps whenever we use our arms. For friends who like fitness, the triceps are particularly familiar, but many friends are not very clear about it. So, where are the starting and ending points of the triceps? To solve this problem, let us take a look at it through the following introduction.

Triceps origin and insertion:

Location: On the back of the upper arm, it has three heads: the long head, the lateral head, and the medial head.

Origin: The long head originates from the inferior glenoid tubercle of the scapula, the lateral head originates from the outer and superior side of the radial nerve groove on the posterior side of the humeral body, and the medial head originates from the inner and inferior side of the radial nerve groove.

Insertion: Olecranon of ulna.

Function: When nearly fixed, it can extend the elbow joint, and the long head can also extend the shoulder joint. When fixed at a distance, extend the upper arm at the elbow joint.

Anconeus

Location: Located behind the elbow joint, in a triangular shape.

Origin: From the lateral epicondyle of the humerus.

Insertion: Inserts at the upper back of the ulna.

Function: Extend and strengthen the elbow joint when nearly fixed. When fixed at a distance, extend the upper arm at the elbow joint.

Through the above introduction, we know where the starting and ending points of the triceps are. This is also a common sense of the body. We must pay attention to it when we do fitness or muscle training in our daily life. In addition, we must also pay attention when practicing the triceps. The triceps is also a muscle group that is not easy to exercise.
