The teres minor (Latin teres meaning 'rounded') is a narrow, elongated muscle of the rotator cuff. The muscle originates from the lateral border and adjacent posterior surface of the corresponding right or left scapula and inserts at both the greater tubercle of the humerus and the posterior surface of the joint capsule.
A variety of methods may be used to diagnose axillary nerve palsy. The health practitioner may examine the shoulder for muscle atrophy of the deltoid muscle. [2] Furthermore, a patient can also be tested for weakness when asked to raise the arm. [2] The deltoid extension lag sign test is one way to evaluate the severity of the muscle weakness.
The axillary nerve is a branch of the brachial plexus that innervates the deltoid and teres minor muscles. This nerve can be injured or damaged in a variety of ways - penetrating injury such as knife or gunshot wounds, surgical trauma, stretch injury (common after motor cycle accidents), and various metabolic or rheumatic conditions that may ...
The nerve lies at first behind the axillary artery, [4] and in front of the subscapularis, [1] and passes downward to the lower border of that muscle.. It then winds from anterior to posterior around the neck of the humerus, in company with the posterior humeral circumflex artery, [2] through the quadrangular space (bounded above by the teres minor, below by the teres major, medially by the ...
The rotator cuff includes muscles such as the supraspinatus muscle, the infraspinatus muscle, the teres minor muscle and the subscapularis muscle. The upper arm consists of the deltoids, biceps, as well as the triceps. Steps must be taken and precautions need to be made in order for the rotator cuffs to heal properly following surgery while ...
The greater tubercle of the humerus is the outward part the upper end of that bone, adjacent to the large rounded prominence of the humerus head. It provides attachment points for the supraspinatus, infraspinatus, and teres minor muscles, three of the four muscles of the rotator cuff, a muscle group that stabilizes the shoulder joint.
