What are the rotator cuff muscles collectively known as?

Scapula muscles
SITS
Deltoid muscles
Pectoralis muscles

The correct answer is: SITS

The rotator cuff muscles are collectively known as "SITS," which refers to the acronym formed by the first letter of each muscle's name: Supraspinatus, Infraspinatus, Teres Minor, and Subscapularis. These muscles play a crucial role in stabilizing the glenohumeral joint (shoulder joint) and supporting shoulder movement. They help facilitate the internal and external rotation of the shoulder, as well as assist in arm elevation. Understanding the term SITS is essential for anyone studying anatomy, especially for fitness professionals, as these muscles are frequently involved in both athletic performance and rehabilitation scenarios. Recognizing this nomenclature can enhance communication with clients and other healthcare professionals regarding shoulder health and functionality.
