Teres Minor Origin Insertion Action And Innervation Kenhub

Teres Minor Origin Insertion Action And Innervation Kenhub Origin and insertion. teres minor originates from the scapula, via two heads that are separated by a groove for the circumflex scapular artery. the attachment site spans the upper two thirds of the lateral border of scapula. the fibers quickly fuse into a single muscle belly which courses superolaterally towards the proximal humerus. It’s matt from kenhub, and in this tutorial, we will discuss the origin, insertion, innervation, and action of the teres minor muscle. along with the supraspinatus muscle, infraspinatus muscle, and subscapularis muscle, the teres minor makes up the rotator cuff , which is a functional, anatomical unit in the upper arm.

Teres Minor Origin Insertion Action And Innervation Kenhub This video explores the origin, insertion, innervation and functions of the teres minor muscle, one of the 4 rotator cuff muscles. test yourself in our rotat. Origin and insertion. infraspinatus muscle lies on the dorsal surface of the scapula, deep to trapezius, and parts of the deltoid and latissimus dorsi muscles. it originates with strong muscle fibers directly from the medial two thirds of the infraspinous fossa, whereas its tendinous fibers arise from the ridges of the fossa. In concert with the other rotator cuff muscles, teres minor is instrumental in providing stability to the shoulder joint, and helps to hold the humeral head in the glenoid cavity of the scapula. assessment: hornblower’s sign [edit | edit source] hornblower's sign can be used to evaluate the teres minor for injuries, particularly tears. 2. arm rotation: the teres minor helps rotate the upper arm laterally or outwards at the shoulder joint. the infraspinatus muscle helps it in this action. an example of the movement is when you pull a door open or spread your palm in front of you. since it works as a lateral rotator, it is antagonistic to rotating the arm medially or inwards.

Figure 1 – teres minor anatomy. origin: the teres minor originates from the lateral border of the scapula, specifically from the upper two thirds of the lateral border. insertion: this muscle inserts into the greater tubercle of the humerus, blending with the posterior fibers of the deltoid muscle. action: the primary function of the teres.
