Nose Anatomy Flashcards
Deep Petrosal Nerve
post ganglionic sympathetic
motor to SM of BVs
travels in the pterygoid canal
Greater Petrosal Nerve
Preganglionis Parasympathetics
branch of facial nerve
mucus membrane secretion
where do posterior ethmoidal air cells drain?
superior meatus
where does the frontal sinus drain?
middle meatus: drains thru the infundibulum and into the hiatus semilunaris region
where do the anterior ethmoidal cells drain?
middle meatus: drains thru the infundibulum and into the hiatus semilunaris region
where does the maxillary sinus drain?
middle meatus also
where does the nasolacrimal duct drain?
inferior meatus
what are the blood supplies to the nose?
external carotid –> sphenopalantine artery
internal carodid –> ophthalmic artery
what are the sensory nerves to the nose?
ophthalmic = anterior + superior olfactory = roof of nose maxillary = posterior wall of nose
maxillary is what hurts when you swab the back of the nose
