Ulnar groove Anterior Medial

The anterior medial ulnar sulcus (lat. sulcus cubital is anterior i. medial i\), also known as the anterior medial sulcus of the arm or ulnar interosseous space, is a deep canal that is located between the radius and ulna bones in the front of the elbow joint. This passage allows nerves and blood vessels to pass through the joint and also allows the bones to move freely in their joints.

The grooves on the anterior and posterior surfaces of the first ray of the arm are located in the longitudinal direction along the arm, on the forearm, respectively, above and below the connection of the first with his arm, in some cases even to the top of the shoulder joint. Both can be associated with muscle tendons. They are sometimes referred to as the "digital flexor tendon canal", although the latter name is usually applied only to the anterior groove. The grooves are characterized by a narrow ellipsoidal opening above and below.

Ulnar groove Anterior medial - (sulculus anterior medialis cubitalis): One of the paired grooves in the form of a groove forming the anterior surface of the cubital fossa. Reaches to the level of the internal condyle of the elbow joint. In the anterior part, it separates from the ulnar nerve the triangular fibrous triangle (triaon cubitalis), and in the posterior part it passes into the internal ulnar ligament, which is supported by the aponeurosis of the biceps brachii muscle.
