Head and neck blood supply

Head and neck blood supply

The head and neck receives the majority of its blood supply through the carotid and vertebral arteries. The neck is supplied by arteries other than the carotids, the right and left subclavian arteries give rise to the thyrocervical trunk. From this trunk, several vessels arise, which go on to supply the neck.Do not forget to always remember the external carotid artery branches:-External carotid provides altogether eight branches:-»One from medial side—Ascending pharyngeal.»Three from the front—Superior thyroid, lingual and facial.»Two from behind—Occipital and posterior auricular.»Two at the end—Superficial temporal and maxillary.Here is an easy way to remember the branches (SALFOPSM):-°S » Superior thyroid artery°A » Ascending pharyngeal artery°L » Lingual artery°F » Facial artery°O » Occipital artery°P » Posterior auricular artery°S » Superficial temporal artery°M » Maxillary artery.
