Brachial Plexus EXPLAINED! (Using a Cadaver)

The video tutorial provides a detailed exploration of the brachial plexus, starting with an overview and identification of the anterior view using the biceps brachii. It covers the carotid sinus, vagus nerve, and the interscalene space where the roots of the brachial plexus emerge. The tutorial explains the formation of trunks from ventral rami, the nerves emerging from C5 and the superior trunk, and the identification of cords and terminal branches. It concludes with a discussion on pectoral nerves and potential anatomical variations.

What is the significance of the interscalene space in relation to the brachial plexus?

Discuss the innervation provided by the axillary nerve.

How do the contributions from the lateral and medial cords of the brachial plexus combine?

What is the role of the medial pectoral nerve and how does it relate to the pectoralis muscles?
