the facial. We discussed about the common carotid
dividing into external internal. The internal
enters the carotid canal, goes into the brain.
That’s fine, we'll leave it there for now.
External carotid in the neck, main branches?
What are the branches of the external carotid
in the neck?
Very good. Ascending pharyngeal.
Sorry? Lingual. Yeah, facial.
Anything else you can think of?
Maxillary. Um, maxillary, occipital,
Occipital. Maxillary, superficial
temporal. Superficial temporal. So what does
this “P” stand for?
Posterior auricular. So the mnemonic to remember
is: Some Angry Lady Figured Out PMS.
So that’s your mnemonic "Some Angry
Lady Figured Out PMS". So superior thyroid,
ascending pharyngeal, lingual, facial, occipital,
posterior auricular, maxillary, and superficial
temporal. Frequently the maxillary artery
is described as the terminal branch, terminal
part of the external carotid. From here, you
have the middle meningeal artery coming off maxillary
artery that goes into through the foramen
spinosum, and that’s the one which lies
at the pterion, this part here, that’s
Say that again? Please.
The maxillary artery is a terminal branch
of your external carotid, and from the maxillary
you have the middle meningeal artery.
So these are the main branches
in the neck for the external
carotid. The internal carotid goes into the
brain and for the exam all you need to remember
is it’s anastomosing with your basilar arteries
coming from the vertebral arteries. So you
have anterior cerebral, middle cerebral, posterior
cerebral. They’re all coming from the vertebral,
internal carotid and forming
the circle of Willis.
Couple of other important things.
The phrenic nerve is quite important.
