Neurovasculature of the tongue

This video tutorial explores the neurovascular anatomy of the tongue, focusing on its arterial supply, venous drainage, and nerve innervation. It covers the external carotid artery and its branches, including the lingual, dorsal lingual, deep lingual, and sublingual arteries. The tutorial also discusses the internal jugular vein, deep lingual vein, dorsal lingual vein, and retromandibular vein. Additionally, it highlights the hypoglossal nerve, lingual nerve, and submandibular ganglion. The video concludes with resources for further learning.
