Muscle, Internal Brachialis (M. Brachialis Internus)

Muscle, Internal Brachialis (M. Brachialis Internus): Anatomical description and functions

The internal brachial muscle (M. Brachialis Internus) is one of the key muscles of the upper limb, located in the shoulder area. Together with other muscles such as the brachialis (M. deltoideus) and biceps brachii (M. biceps brachii), the brachialis intrinsic muscle plays an important role in the movement of the shoulder and forearm.

The anatomical term "brachialis internus" refers to the location of this muscle relative to other structures in the shoulder region. It is located deeper than the brachialis muscle (M. Deltoideus) and is attached to the lower part of the humerus (humerus) and the glenoid line. The muscle is shaped like a triangle and extends from the bottom of the shoulder to the elbow joint.

The brachialis intrinsic muscle performs several important functions. Its main function is to flex the forearm at the elbow joint. When we raise our arm or flex our forearm, the brachialis intrinsic muscle is activated, contracting and creating movement. This muscle is also involved in stabilizing the shoulder joint and helps maintain the vertical position of the shoulder.

Training the brachialis intrinsic muscle is an important aspect of developing upper extremity strength and functionality. Exercises to strengthen this muscle may include dumbbells, machines, or bodyweight exercises. Examples of such exercises include dumbbell curls or machine forearm curls.

Disorders or injuries to the brachialis intrinsic muscle can limit shoulder movement and cause pain. If you experience pain or discomfort in the brachialis intrinsic muscle area, it is recommended that you consult a doctor or physical therapist for evaluation and treatment.

In conclusion, the muscle, the brachialis internus (M. brachialis internus), is an important component of the muscles of the upper limb. Its function includes flexion of the forearm and stabilization of the shoulder joint. Regular training and proper care of this muscle can help strengthen and maintain optimal functionality of the shoulder region.
