Respiratory Flashcards
the two divisions of the respiratory system
conducting portion, respiratory portion
What divides the respiratory portion from the conducting portion
the terminal bronchiole/ respiratory bronchiole junction
conchae (konk-eye)
the three shelf-like bones of each side of the nasal cavity
respiratory epithelium
pseudostratified columnar with goblet cells
what swells up in the nose to prevent air from passing through both sides (prevent drying)
the large veins in the lamina propria form an erectile tissue: SWELL BODIES
mucoperiosteum
the direct connection between the lamina propria of the nose and the periosteum of the nasal bones
what is the sensing portion of the olfactory receptor cells called
dendrite
where do the protein receptors for oderiferous molecules lie
in the stereocilia of olfactory cell knobs
the 3 types of cells in olfactory epithelium
1) olfacctory 2) sustentaculer (supporting) cells 3) basal cells
what is the morphology of sustentacular cells
goblet-like with micovili
what is the function of basal nasal epithelial cells
they serve as stem cells for both supportive and olfactory cells
Bowman’s glands
lamina propria-residing, they secrete the serous fluid to solvate molecules for olfactory detection
cribriform plate of the ethmoid bone
the structure through which the unmyelinated olfactory axons (and other axons) pass to synapse with the olfactory bulb
what type of cartilage supports the epilottis
elastic cartilage
what type of epithelium make up the two sides of the epiglottis
the anterior side is stratified squamous, the posterior side is respiratory
