What Are The 4 Tendons Of The Rotator Cuff?

The rotator cuff consists of four tendons, each attached to one of the four muscles that help stabilize and move the shoulder joint.

4 Tendons & The Muscles They Correspond To

• 1. Supraspinatus Tendon

  • Muscle – Supraspinatus
  • Function – Assists in lifting the arm away from the body (abduction) and stabilizes the shoulder joint.

• 2. Infraspinatus Tendon

  • Muscle – Infraspinatus
  • Function – Helps rotate the arm outward (external rotation) and provides stability to the shoulder.

• 3. Teres Minor Tendon

  • Muscle – Teres Minor
  • Function – Works with the infraspinatus to rotate the arm externally and stabilize the shoulder.

• 4. Subscapularis Tendon

  • Muscle – Subscapularis
  • Function – Rotates the arm inward (internal rotation) and stabilizes the shoulder joint.

These tendons work together to stabilize the shoulder joint while allowing a wide range of movements, including lifting, rotating, and reaching.
