Where does the triceps attach?

The triceps is a muscle group in our body. Friends who work out regularly should know that this group of muscles will be exercised when doing equipment training. However, many friends do not know where the attachment point of the triceps is, and some people do not know how to exercise when working out. So where is the attachment point of the triceps? Let’s learn more about it through the following introduction.

Location and shape: Located behind the humerus. The muscle is clearly visible when the elbow is extended. This muscle has three heads: the long head, the medial head, and the lateral head. The long head is a biarticular muscle, while the medial and lateral heads are monoarticular muscles.

Starting point: The long head originates from the infraglenoid tubercle of the scapula, the lateral head originates from the bone surface above and outside the radial nerve groove, and the medial head originates from the bone surface below and inside the radial nerve groove.

Insertion: The three heads form a muscle belly, which inserts into the olecranon of the ulna with tendons.

Function: When nearly fixed and contracted, the long head extends the upper arm at the shoulder joint; when the three heads contract together, the forearm extends at the elbow joint. When performing distal fixed contraction, the upper arm is mainly extended at the elbow joint.

Exercise method: Weighted lifting, bench press and other exercises can develop the strength of the triceps; frequently doing the "towel back rub" action can develop the elasticity of the muscle.

Through the above introduction, we know where the insertion point of the triceps is. When exercising, we should also pay attention to the training of this group of muscles. The method is also very important. Another thing we need to pay attention to is the effective method, which is particularly meaningful for muscle training. In addition, we should also pay attention to the method that suits us.
