INFRASPINATUS MUSCLE Meaning and Definition

  1. The infraspinatus muscle is a thick and triangular-shaped muscle located on the posterior (back) surface of the scapula (shoulder blade). It is one of the four muscles that make up the rotator cuff, along with the supraspinatus, teres minor, and subscapularis muscles.

    The primary function of the infraspinatus muscle is to externally rotate the arm at the shoulder joint. This means that it helps to turn the upper arm outward, away from the body. It also contributes to the stabilization of the shoulder joint by holding the humeral head (upper arm bone) securely within the glenoid fossa (socket) of the scapula.

    The infraspinatus muscle arises from the infraspinous fossa, which is a concave depression on the posterior surface of the scapula. It travels inferiorly and laterally, attaching to the greater tubercle of the humerus (the upper arm bone) through its thick tendon. This tendon plays a crucial role in transmitting the force generated by the muscle to the bone, enabling movement.

    Effective strengthening and conditioning of the infraspinatus muscle are important for maintaining shoulder stability and promoting proper movement of the arm. Exercises like external rotation using resistance bands or dumbbells can help to target and strengthen this muscle. In certain cases of injury or dysfunction, medical professionals may recommend specific rehabilitation exercises to rehabilitate and restore proper functioning of the infraspinatus muscle.

Etymology of INFRASPINATUS MUSCLE

The word "infraspinatus" comes from Latin and has a two-part etymology:

1. "Infra": It is a Latin preposition meaning "below" or "underneath".

2. "Spinatus": This word comes from the Latin word "spina", which means "spine" or "thorn". The suffix "-atus" indicates a possessive or having a characteristic related to the root word.

Therefore, the term "infraspinatus" refers to a muscle situated below or underneath the spine. It is named so because the infraspinatus muscle is located on the posterior (back) side of the scapula (shoulder blade) below the spine of the scapula.
