Superficial back muscles

The video tutorial covers the anatomy, innervation, and functions of the pectoral muscles, specifically the pectoralis major and minor. It explains their role in shoulder movement, their anatomical relations with the brachial plexus and subclavian vessels, and their specific functions in arm movement and rib elevation. The pectoralis major is divided into clavicular and sternocostal parts, each with distinct functions, while the pectoralis minor aids in scapular movement and rib elevation during inspiration.

What are the two main muscles that make up the pectoral muscles?

Describe the location and relationship of the pectoralis muscles to the brachial plexus.

Explain how the clavicular and sternocostal parts of the pectoralis major muscle differ in function.

What are the functions of the pectoralis minor muscle?

How does the pectoralis minor assist during inspiration?
