Definition

1. Noun:
   • Either of two muscles in the shoulder region that move the shoulders and arms: The "teres muscle" refers specifically to one of two distinct muscles—the teres major or the teres minor—located near the shoulder blade (scapula). These muscles are involved in the rotation and movement of the arm.

Usage

• The term "teres muscle" is a precise anatomical term. In most contexts, the specific muscle (teres major or teres minor) is named. It is used in medical, biological, and fitness discussions.
• Example: "The surgeon carefully identified the torn teres muscle before proceeding with the repair."

Examples

• Noun:
  • The teres muscle, along with the rotator cuff, stabilizes the shoulder joint.
  • Pain in the back of the shoulder may indicate a strain of the teres muscle.
  • Strengthening the teres minor, a specific teres muscle, can help prevent shoulder injuries.

Advanced Usage

• "Teres major": The larger of the two teres muscles. It originates on the lower scapula and inserts on the upper arm bone (humerus), functioning to internally rotate and adduct the arm.

  • The latissimus dorsi and teres major work together during pulling motions.

• "Teres minor": The smaller of the two teres muscles. It is part of the rotator cuff group, originating on the scapula and inserting on the humerus, functioning to externally rotate the arm.

  • A tear in the teres minor can significantly limit external rotation of the shoulder.

Variants and Related Words

• Teres (adj): A Latin-derived term meaning "rounded and long," describing the shape of these muscles.
• Rotator cuff (n): A group of muscles and tendons that stabilize the shoulder, which includes the teres minor muscle.
• Shoulder girdle (n): The bony and muscular structure to which the teres muscles attach.

Synonyms

• Shoulder muscle (general, non-specific term)
• Rotator muscle (contextual, as the teres minor is part of the rotator cuff)

Notes on Meaning

• The term "teres muscle" almost always refers to one of the two specific muscles (major or minor). It is rarely used as a standalone, generic term without further specification in technical contexts.
• In common, non-medical language, people are more likely to refer to "shoulder muscles" or a "pulled muscle in the shoulder" rather than naming a specific teres muscle.
