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
