# Understanding the Subclavius Muscle: Function, Anatomy, and Clinical Relevance The subclavius muscle is a small but significant muscle located beneath the clavicle (collarbone) that plays a crucial role in shoulder mechanics. While often overlooked in general anatomy, this tiny muscle is vital for stabilizing the shoulder joint and facilitating smooth arm movements. This article explores the anatomy, function, clinical importance, and how to care for the subclavius muscle. ## What is the Subclavius Muscle? The subclavius muscle is a small, fan-shaped muscle located in the anterior triangle of the neck, lying deep beneath the clavicle and the pectoralis minor. It originates from the medial surface of the first rib and inserts onto the subclavial articular surface of the scapula (shoulder blade), specifically near the inferior concealed surface of the clavicle.
