Epicondyle of the Humerus Medial

Medial epicondyle of the humerus: anatomical description and functions

The medial epicondyle of the humerus, also known as the medial epicondyle (lat. medialis), is an important structure in the anatomy of the shoulder joint. It is located on the medial (inner) side of the humerus and plays a key role in the support and movement of the upper limb.

The anatomical epicondyle of the humerus medial has the shape of a small protrusion and forms the upper part of the lateral fossa of the humerus. It is located next to the lateral epicondyle and forms a boundary for the various muscles and tendons associated with the shoulder joint.

Functionally, the medial epicondyle of the humerus plays an important role in stabilizing the shoulder joint and is involved in the movement of the upper limb. Various muscles passing through this area attach to the epicondyle and perform a variety of shoulder movements.

One of the main muscles associated with the medial epicondyle is the medial head of the triceps brachii muscle. This muscle originates on the back of the shoulder and attaches to the medial epicondyle. The medial head of the triceps brachii muscle performs the function of shoulder extension and takes an active part in turning and lifting the upper limb.

In addition to the medial head of the triceps brachii, other muscles and tendons also attach to the medial epicondyle of the humerus. Examples of such muscles include the anconeus, teres minor, and long head of biceps brachii.

The overall function of the medial epicondyle of the humerus is to maintain stability of the shoulder joint and provide strength and accuracy of movement of the upper extremity. Through its attachments to various muscles and tendons, the medial epicondyle plays an important role in everyday motor tasks such as lifting, pulling, and turning the arm.

In conclusion, the medial epicondyle of the humerus is an important anatomical element of the shoulder joint. It serves as the basis for the attachment of muscles and tendons that provide movement and stability to the upper limb. Understanding the anatomy and function of the medial epicondyle of the humerus is an important aspect for medical professionals such as orthopedists, physical therapists, and athletic trainers when diagnosing and treating injuries and diseases of the shoulder joint.

There are usually two epicondyles at the level of the elbow joint. In anatomy, it is customary to divide the medial and lateral groups.

Medial epicondyle of the humerus. Medial epicondyle - located on the posterior surface of the shoulder joint (located opposite the medial epicondyle). Both epicondyles connect to the superior part of the medial joint capsule. In addition, the medial epicondyle attaches the ligament passing to the brachial artery, which originates from the visceral edge of the myrtle muscle, which is an arteriotonia, and, finally, the adductor muscle of the brachial body (the upper edge of the medial epicondyle is connected to the tendon
