094 Innervations Of The Extrinsic Back/Shoulder Muscles

Leslie Samuel discusses the innervation of extrinsic back muscles, focusing on both superficial and deep muscles. The trapezius muscle is innervated by the accessory nerve (cranial nerve 11), while the latissimus dorsi is innervated by the thoracodorsal nerve. Deep muscles like levator scapulae, rhomboid minor, and rhomboid major are innervated by the dorsal scapular nerve. The video concludes with a review of these innervations and encourages viewers to engage with more content on the website.
