Teres Major Muscle Action

Understanding teres majormuscle action requires examining multiple perspectives and considerations. Teresmajormuscle: Anatomy, function, clinical aspects | Kenhub. By contracting, it pulls the humerus posteriorly (extension) and rotates it medial towards the trunk (internal rotation). Additionally, it contributes to the stabilization of the shoulder joint. In this article, we will discuss the anatomy and function of the teres major muscle. Teres Major: Action, Origin, Insertion, Innervation & Diagram.

When its point of attachment to the humerus is fixed, the teres major assists the latissimus dorsi and pectoralis major to move the body closer to the arm superiorly. For example, doing pull-ups or climbing rocks; this is why the muscle is sometimes referred to as a ‘climbing muscle.’. Teres major muscle - Wikipedia. The teres major muscle (from Latin teres, meaning "rounded") is positioned above the latissimus dorsi muscle and assists in the extension and medial rotation of the humerus.

Stretch or impact injuries to the teres major muscle, sustained while playing sports or in motor vehicle accidents, as well as falls onto the lateral scapula are implicated in the evolution of teres major injuries. Teres Major Muscle – Attachments, Action & Innervation.

This perspective suggests that, teres major is a thick and ovoid muscle in the upper arm. Despite their similar names, Teres major has different actions and innervation from the Teres minor. It's mainly responsible for the medial rotation of the arm and it also contributes to static posture and arm-swinging. Teres Major Muscle | Complete Anatomy - Elsevier. Explore the Teres Major muscle's origin, action, and innervation. Understand its role in arm movement and shoulder stabilization.

Building on this, teres Major - Attachments - Actions - TeachMeAnatomy. Actions: Adduction, extension and medial rotation of the upper limb at the shoulder. Innervation: Lower subscapular nerve. Equally important, explore, cut, dissect, annotate and manipulate our 3D models to visualise anatomy in a dynamic, interactive way. Prosection of the posterior shoulder region. The Teres Major Muscle: A Powerful Posterior Shoulder Muscle.

In relation to this, it is one of the seven scapulohumeral muscles that act around the glenohumeral joint to facilitate shoulder movement. The teres major is a thick muscle of the shoulder joint. It is sometimes called "lat's little helper" because of its synergistic action with the latissimus dorsi. Anatomy, Shoulder and Upper Limb, Teres Major Muscle. The teres major is a thick but flattened, rectangular muscle that extends from the inferior posterior scapula to the medial lip of the intertubercular groove of the humerus.

[1] [2] It functions synergistically with the latissimus dorsi to extend, adduct, and internally rotate the humerus.
