Bicipital Groove Floor

The structure indicated is the intertubercular sulcus of the humerus.

Bicipital groove floor. It is the lateral wall of the axilla. The teres major inserts on the medial lip of the groove. It runs obliquely downward and ends near the junction of the upper with the middle third of the bone. D groeve a groove between the greater and lesser tubercles of the humerus for passage of the tendon of the long head of the biceps muscle.

The bicipital groove also known as the intertubercular sulcus or sulcus intertubercularis is the indentation between the greater and lesser tuberosities of the humerus that lodges the biceps tendon. The insertion of the latissimus dorsi is found along the floor of the bicipital groove. The intertubercular sulcus also known as the intertubercular groove or bicipital groove is a groove separating the greater and lesser tubercles of the humerus. The bicipital groove is typically 4 6 mm deep 1.

It is the lateral wall of the axilla. It also transmits a branch of the anterior humeral. The teres major inserts on the medial lip of the groove. It does not seem to.

The insertion of the latissimus dorsi is found along the floor of the bicipital groove. The bicipital groove intertubercular groove sulcus intertubercularis is a deep groove on the humerus that separates the greater tubercle from the lesser tubercle the bicipital groove lodges the long tendon of the biceps brachii between the tendon of the pectoralis major on the lateral lip and the tendon of the teres major on the medial lip. The long biceps tendon lbt sits within the bg. The bicipital groove bg of the proximal humerus is a groove in the humeral head formed by the medial and lateral tuberosities fig.

Bicipital groove intertubercular sulcus of humerus lies between greater lesser tubercles of humerus and transmits long head of biceps. Factors analyzed in evaluating the bicipital groove included the medial wall angle depth and width of the intertubercular sulcus and presence or absence of bony spurs arising from the floor or medial wall of the groove. Bicipital groove or intertubercular groove divides the lesser and greater tubercles and afterwards proceeds interiorly over the proximal shaft of the humerus the tendon of the long head of the biceps brachii travels via this sulcus. It contains the tendon of the long head of the biceps brachii muscle which is ensheathed in a synovial reflection of the.

Bicipital groove of right humerus. A deep intertubercular sulcus a k a. The supratubercular ridge was observed as an osseous protuberance in about one half of the population. It runs obliquely downward and ends near the junction of the upper with the middle third of the bone.

The bg prevents the lbt from dislocating during movement of the arm.
