Subclavius

Subclavius (pronunciation: /sʌbˈkleɪviəs/) is a small triangular muscle, located in the upper chest, beneath the clavicle. It plays a crucial role in the functioning of the shoulder.

Etymology

The term "Subclavius" is derived from Latin, where "sub" means under and "clavius" refers to the clavicle. Hence, the term literally means "under the clavicle".

Function

The primary function of the Subclavius muscle is to stabilize the clavicle in its position. It helps in the downward pull of the clavicle, and also aids in superior rotation and abduction of the scapula.
