Anatomy of the external carotid Flashcards
Where do the left and right common carotids originate from
left originates from the arch of the aorta directly
right originates from the brachiocephalic trunk
at which level does the common carotid bifurcate into the internal and external
C3/C4
what is the course of the external carotid artery
- originates the upper border of the thyroid cartilage
- ascends between the mastoid process of the temporal bone and mandible
- within the parotid gland divides into its terminal branches
