Biceps Lateral Groove: Anatomical Description and Role in Arm Movement

The biceps groove lateralis, also known as sulcus bicipitalis lateralis, pna, bna, sulcus bicipitalis radialis, jna, or syn. The humeral groove is lateral and is a deep groove on the anterior surface of the upper third of the humerus. This anatomical structure is important for understanding the biceps muscle, which is one of the main muscles of the shoulder girdle.

The biceps muscle consists of two heads: short and long. The short head begins on the top of the scapula, and the long head begins on a horizontal groove on the anterior surface of the humerus, below the biceps groove. Both heads are connected and inserted onto the ulna bone. The biceps lateralis groove is located on the anterior surface of the humerus between the short and long heads of the muscle.

The role that the biceps lateralis groove plays in arm movement is that it is the attachment site for the long head of the muscle. The long head muscle is the main flexible muscle of the forearm. When the muscle contracts, it causes flexion of the forearm at the elbow joint. The biceps lateralis groove also serves to protect the long head of the muscle from dislocation during arm movements.

Impaired function of the biceps lateralis groove can lead to shoulder pain, limited arm mobility, and impaired muscle function. Damage to the groove can occur due to injury or overuse of the muscle.

In conclusion, the biceps lateralis groove plays an important role in biceps muscle function and arm movement. Its anatomical position and function can be disrupted by injury or excessive stress on the muscle. Understanding the role and significance of the biceps lateralis groove can help in the diagnosis and treatment of injuries and diseases associated with the shoulder girdle and forearm.

The biceps groove lateralis, also known as sulcus bicipitalis lateralis, pna, bna or sulcus bicipitalis radialis, jna, is an anatomical structure of the upper limb that plays an important role in the movement of the shoulder joint.

The biceps lateralis groove is located on the anterior surface of the humerus (humerus) and serves as the attachment point for the two heads of the biceps muscle of the upper limb. The biceps muscle (m. biceps brachii) consists of a short head (caput breve) and a long head (caput longum), which both attach to the groove.

This groove is an important anatomical structure because it provides stability and efficiency to the biceps muscle during contraction and extension. This groove allows the biceps muscle to glide easily during contraction and extension, allowing smooth movement of the shoulder joint.

It is important to note that the biceps lateralis groove is also the site for the insertion of other structures such as the shoulder capsule tendon and small ligaments. These structures play a role in stabilizing the shoulder joint and maintaining its normal functioning.

Pathologies associated with the biceps lateralis groove may include inflammation, rupture, or irritation of the tendons associated with this area. Injury, repetitive motion, or excessive stress on the shoulder can cause such pathologies. If symptoms such as pain, limited movement, or instability of the shoulder joint occur, it is recommended to consult a doctor for diagnosis and treatment.

In conclusion, the biceps lateralis groove is an important structure of the shoulder joint for stability and efficient functioning of the biceps muscle of the upper extremity. Understanding this anatomical structure helps doctors and shoulder health specialists diagnose and treat possible pathologies associated with this area.
