The greater tubercle, lesser tubercle, and intertubercular sulcus are located near the proximal end of the humerus.
The muscle you are referring to is the subscapularis muscle. It originates on the subscapular fossa of the scapula and inserts on the lesser tubercle of the humerus. It is responsible for medial rotation of the shoulder joint.
The femur bone has trochanters. The greater trochanter is located at the top of the femur where the hip muscles attach, and the lesser trochanter is located on the inner side of the femur where the thigh muscles attach.
The ulna is only considered inferior in strength and size. Because the ulna is smaller than the humerus, it is weaker. Though, the ulna is not lesser than the humerus because each and every bone in the body is needed and is very important, which is the main definition of inferior, which is 'lesser than'.
The anatomical neck of the humerus is a constriction just below the head of the humerus bone where it joins the greater and lesser tubercles. It serves as the attachment site for the joint capsule and the ligaments that stabilize the shoulder joint. While it is an anatomical landmark, it does not have a direct function in terms of movement or muscle attachment.
the lesser tubercle of the humerus
The rotator cuff muscles are referred to occasionally as the SITS muscles. The Supraspinatus, Infraspinatus, Teres minor and the subscapularis. The Supras. originates on the scapula and inserts on the humerus. The Infras. originates on the scapula and inserts on the humerus(greater tubercle. The Teres minor originates on the scapula and inserts on the humerus. The Subscapularis originates on the scapula and inserts on the humerus(lesser tubercle). The function of this muscle group is to stabilize the shoulder joint. Hope this helps.
The greater tubercle, lesser tubercle, and intertubercular sulcus are located near the proximal end of the humerus.
The humerus contains both the greater and lesser tubercles, as well as the trochlea and capitulum. The greater tubercle is located laterally, while the lesser tubercle is found anteriorly on the proximal end of the humerus. The trochlea and capitulum are located at the distal end of the humerus, forming part of the elbow joint.
The muscle you are referring to is the subscapularis muscle. It originates on the subscapular fossa of the scapula and inserts on the lesser tubercle of the humerus. It is responsible for medial rotation of the shoulder joint.
The groove found between the greater and lesser tubercles of the humerus is called the intertubercular groove, or the bicipital groove.
The prime mover for shoulder internal rotation is the subscapularis muscle, which is one of the four muscles that make up the rotator cuff. It originates on the subscapular fossa of the scapula and inserts on the lesser tubercle of the humerus. Contraction of the subscapularis muscle causes internal rotation of the shoulder joint.
The femur bone has trochanters. The greater trochanter is located at the top of the femur where the hip muscles attach, and the lesser trochanter is located on the inner side of the femur where the thigh muscles attach.

The ulna is only considered inferior in strength and size. Because the ulna is smaller than the humerus, it is weaker. Though, the ulna is not lesser than the humerus because each and every bone in the body is needed and is very important, which is the main definition of inferior, which is 'lesser than'.
The head of the humerus is laterally and medially convex. The medial convexity fits into the glenoid fossa, and the lateral convexity, the lesser tuberosity, provides a site for muscle attachment.
Just the femur has a trochanter. It has a greater and a lesser trochanter. They give depth and stability to the joint.
