Oct 30, 2023 · Lesser tubercle The lesser tubercle is located anterior to the anatomical neck and has a smooth, palpable muscular impression. The lateral part forms the medial margin of the intertubercular sulcus.

The projection of the lesser tubercle is anterior from the junction that is found between the anatomical neck and the shaft of the humerus and easily identified due to the intertubercular sulcus (Bicipital groove).

Study with Quizlet and memorize flashcards containing terms like where is the lesser tubercle located, where is greater tubercle located, what size IR and KV for humerus and more.

Aug 22, 2016 · FIGURE 5-11 Greater tubercle, bicipital groove, and lesser tubercle of the humerus: The greater tubercle is located on the lateral side of the bicipital groove; the lesser tubercle is located on the medial side.

Aug 11, 2021 · Lesser Tubercle (Lesser Tuberosity): It is much smaller than the greater tubercle located inferior to the head, bearing only an anterior surface. This is where the the fourth and last rotator cuff muscle, the subscapularis, attaches.

The lesser tubercle is located medial to the coracoid process on the anterior aspect of the humerus. Identifying the Lesser Tubercle. Put your fingers just medial to the coracoid process on the shoulder's anterior side. Locate the lesser tubercle by gently palpating the region and feeling for a bony protrusion.

The lesser tubercle (lesser tuberosity, or tubercle of Weber) is the small eminence found on the anterior aspect of the proximal end of the humerus. It projects anteriorly from the junction between the anatomical neck and body of the humerus.

As the names suggest, the “greater” tubercle of the humerus is the “larger” knob structure located laterally. The “lesser” tubercle is the “smaller” knob, and it’s located medially. These tubercles allow for the attachment of muscles in your back, as well as the pectoralis major muscle.

The lesser tuberosity is located inferior to the head, on the anterior part of the humerus, Its very prominent and palpable. Bicipital (intertubercular) groove is located between the two tuberosities.

Lesser tubercle in profile on the medial side. Outline of greater tubercle superimposed over humeral head. lateral view of proximal humerus in relationship to the glenohumeral articulation, coracoid process of scapula on end. Arm raised superiorly above the body.
