Lingual Artery #Anatomy #mbbs #education #bds #headandneckanatomy #arteries

Lingual Artery • arises from the external carotid artery opposite the tip of the greater cornua of the hyoid bone. • It is tortuous in its course. • Its course is divided into three parts by the hyoglossus muscle. • The first part lies in the carotid triangle. • It forms a characteristic upward loop which is crossed by the hypoglossal nerve. • The lingual loop permits free movements of the hyoid bone. • The second part lies deep to the hyoglossus along the upper border of hyoid bone. • It is superficial to the middle constrictor of the pharynx. • The third part is called the arteria profunda linguae, or the deep lingual artery. • It runs upwards along the anterior border of the hyoglossus, and then hoizontally forwards on the undersurface of the tongue as the fourth part. • In its vertical course, it lies between the genioglossus medially and the inferior longitudinal muscle of the tongue laterally. • The horizontal part of the artery is accompanied by the lingual nerve. • During surgical removal of the tongue, the first part of the artery is ligated before it gives any branch to the tongue or to the tonsil. ---------------------------------------------------------------------------------------------------------------- My website - https://human-anatomy-lessons.busines...
