Scapular Protractors | Origins, Insertions, Innervations, & Actions

This video tutorial explores the anatomy and function of the pectoralis minor and serratus anterior muscles. It discusses their origins, insertions, innervations, and actions, emphasizing their roles in scapular protraction and stabilization during movements like bench presses and boxing. The serratus anterior is highlighted as the primary muscle for scapular protraction, earning it the nickname 'boxer's muscle'. The tutorial also provides visual aids to enhance understanding of these muscles' anatomical positions and functions.
