Teres minor muscle
Teres minor muscle
The Teres minor muscle (pronunciation: /ˈtɛrɪs ˈmaɪnər ˈmʌsəl/) is a narrow, elongated muscle of the rotator cuff. The muscle originates from the lateral border of the scapula and inserts into the humerus. It functions to laterally rotate the arm and is innervated by the axillary nerve.
Etymology
The term "Teres" is derived from the Latin word 'teres' meaning 'rounded' or 'smooth', and "minor" is Latin for 'smaller'. This is in reference to the muscle's rounded shape and its size in comparison to the nearby Teres major.
Function
The Teres minor muscle, along with the other muscles of the rotator cuff, stabilizes the glenohumeral joint during arm movements. It also assists in the lateral rotation of the arm.
Clinical significance
Injury to the Teres minor muscle or the axillary nerve can result in weakness or inability to laterally rotate the arm, a condition known as rotator cuff syndrome. This can be diagnosed through physical examination and confirmed with magnetic resonance imaging (MRI).
