Define spheno-ehtmoidal recessA space located superior to the superior chonchae. It is an important site because this is where the olfactory nerves are distributed.
What sinus empties into the spheno-ehtmoidal recess sphenoid sinus
Name the 4 paranasal sinusesfrontal, ethmoid, sphenoid and maxillary
How do the sinuses communicate with the nasal cavity?They empty into the nasal cavity.
empty the sphenoid sinusempties into the sphenoi-ethmoidal recess
empty the nasolacrimal ductit empties into the inferior meatus
empty the posterior ethmoidal sinusit empties into the superior meatus via the posterior ethmoidal ostium
empty the maxillary sinusit empties into the maxillary ostium, which is located in the hiatus semilunaris
empty the anterior ethmoidal sinusit empties into the anterior ethmoidal ostium, which is located in the hiatus semilunaris
empty the frontal ethmoidal sinusit empties into the frontonasal duct, whcih will empty into the infundibulum, whcih is located within the hiatus semilunaris
what holes are found in the hiatus semilunaristhere are 3 foramen: anterior ethmoidal and maxillary osteum and the infundibulum, through which the frontonasal duct empties into.
Define: ethmoidal bullaa structure located superiorly to the hiatus semilunaris
