Nasal Bones and Structures - Earworm

Nasal cavity is where respiration starts Filtering, warming, let's go through its parts Frontal bone's nasal part, strong shield With nasal bones, protection they yield Max-ill-a forms floor, side walls too Pal-a-tine behind, air passage true Vomer and ethmoid's perpendicular plate Form septum, airflow they separate Crib-ra-form plate, a porous screen Olfactory nerves pass, unseen Ethmoid's conchae, middle and superior Increase surface area, nothing inferior Inferior conchae, bones on their own Turb-in-ates three, in each zone Moisten and filter, temperature control Air conditioning's their primary role Sphenoid bone, at cavity's rear Its sinus opens, drainage clear Sphe-noid-al rostrum anchors septum's base Stabilizing structure in this bony space Lac-ri-mal bones, small but key House na-so-lac-ri-mal ducts, you see Tears drain from eyes to nasal floor Maintaining moisture evermore Co-ayne-ah, where nose meets throat Faren-gee-al es-mas, transition note From external nares to internal too Air's path complex, not just passing through Nasal valve, where airflow's controlled External and internal, structure bold Naso-pharynx, where air and ear connect Eustachian tube, middle ear protect Olfactory bulb sits just above Crib-ra-form's holes, perfect fit like a glove Mucosa lines all, with cilia fine Trapping particles, keeping air clean, sublime Trigeminal nerve, sensory input high Facial nerve, parasympathetic supply Olfactory, smells it does perceive In nasal cavity, functions interweave Nasal cycle, congestion alternates Every few hours, airflow it regulates From first breath to last scent we receive Nasal cavity's complexity we can't misconceive
