Pectoral Muscle - English Definition & Meaning

Definition

Pectoral muscles are the muscles located on the front of the chest. The main one is the pectoralis major, a large, fan-shaped muscle. Think of them as your 'pecs,' the muscles that give your chest definition. These muscles are primarily responsible for arm adduction, flexion, and internal rotation. They contribute to movements such as pushing, throwing, and hugging. Developing these muscles is common for both athletic performance and aesthetic purposes.

Etymology

"Pectoral" comes from Latin "pectus," meaning "breast" or "chest." "Muscle" derives from Latin "musculus," meaning "little mouse," referring to its shape under the skin. The combination describes the muscle located on the chest. These terms have been consistently used in anatomy and fitness for centuries.
