Nasal Cavity Flashcards
Name the nerves which run on the nasal septum.
Nasopalatine nerve and anterior ethmoidal.
Name the nerves which supply the lateral aspect of the nasal cavity.
Posterior superior lateral nasal nerve Posterior inferior lateral nasal nerve Anterior ethmoidal Anterior Superior alveolar Infraorbital nerve
Name the blood vessels supplying the nasal cavity
Greater palatine Nasal branch of superior labial artery Anterior ethmoid Posterior ethmoid Sphenopalatine Artery
Name the venous drainage of the nose
Anterior ethmoidal vein Posterior ethmoidal vein Nasopalatine vein Sphenopalatine vein Superior labial vein
Name the regions of the nasal cavity
Respiratory region
Olfactory region
Nasal vestibule
What is the nasal vestibule?
This is the space immediately posterior to the nares before it opens out into the respiratory region.
What bones form the lateral wall of the nasal cavity?
Inferior conchae, maxillary, ethmoid
What is the ethmoid infundibulum?
This is a space lateral to the middle meatus and uncinate process of the ethmoid bone. it allows communication between the nasal cavity and the frontal and maxillary sinuses.
Name the bones which form the roof of the nasal cavity,
Ethmoid, frontal, nasal
Name the bones which form the bony part one nasal septum.
Vomer and perpendicular plate of the ethmoid bone.
Name the structures which form the floor of the nasal cavity,
The horizontal plate of the palatine bone and the palatine plate of the maxillary bone.
name The foramen found in the superior posterior lateral aspect of the nasal cavity.
Sphenopalatine foramen,
Which cranial nerve supplies the nasal cavity?
I - Olfaction
V - GSA
VII - GVE to nasal glands
Is there any drainage of the nasal cavity into the cranial cavity?
Vein through foramen caecum
Superior ophthalmic vein drainage from anterior and posterior ethmoid veins.
Name the structure which transmits air from the ethmoidal infundibulum to the frontal sinus.
Frontal recess
