This video will cover the: – Anatomy of the Common Carotid Artery – Anatomy of the External Carotid artery – Course and Side branches – Blood supply of the Teeth – Blood supply of the Nasal Cavity Common Carotid Artery: – Right Common Carotid Artery comes from the Aorta – Left Common Carotid Artery comes from the Brachiocephalic trunk – Ascends without sidebranches – Divides at the upper border of the thyroid cartilage – Has Carotid Body External Carotid Artery: – Mneumonic: Some Anatomists Like Freaking Out Poor Medical Students Anterior Side branches of External Carotid Artery: – Superior Thyroid artery – muscular branches and Superior Laryngeal Artery – Lingual Arery – Deep Lingual Artery, Dorsal Lingual Artery, Sublingual Artery – Facial Artery ○ Mneumonic for the Facial Artery: TAGS ALL ○ Cervical Branches of facial artery: TAGS § Tonsillary Artery § Ascending Facial Artery § Glandular Artery § Submental Artery ○ Facial Branches of facial artery: ALL § Angular artery – anestemose with dorsal nasal artery § Superior and Inferior Labial Artery § Lateral Nasal Artery Medial Side branches of External Carotid Artery: – Ascending Pharyngeal – Posterior Meningeal artery, Inferior Tympanic artery Posterior Side Branches of External Carotid Artery: – Occipital artery – Mastoid artery and Sternocleidomastoid artery – Posterior Auricular artery – Auricular branch and stylomastoid artery Terminal Branches: – Maxillary Artery ○ Temporomandibular Joint § Deep auricular artery § Anterior tympanic artery § Middle meningeal artery – Superior tympanic branch □ Middle meningeal rupture will lead to an epidural hematoma (bleeding) giving a painful headache § Inferior Alveolar Artery – Mental Branch, Dental and Peridental branches, mylohyoid branch ○ Infratemporal Fossa § Masseteric artery § Anterior and Posterior deep temporal artery § Pterygoid branches § Buccal artery ○ Pteygopalatine fossa § Superior Posterior Alveolar artery § Infraorbital artery – Superior Alveolar Artery § Descending palatine artery – Lesser palatine and greater palatine artery § Sphenopalatine artery § Artery of the pterygopalatine canal – Superficial Temporal Artery ○ Frontal Branch – anestemose with the supraorbital artery of ophthalamic artery ○ Parietal Branch – anestemose with the posterior auricular artery and the occipital artery ○ Side Branches of the temporal artery § Anterior auricular § Transverse facial artery – parotid gland, masseter muscle, skin § Middle temporal artery Blood supply of the teeth – Inferior Alveolar artery – Superior Anterior Alveolar Artery – Superior Posterior Alveolar Aretry Blood supply of the nasal cavity – Greate palatine artery – Sphenopalatine artery – Anterior and Posterior ethmoidal artery – Superior Labial artery – These arteries make Kisselbach’s area or Little’s area which is the reason for nosebleed when they rupture in the nasal septum
