Special senses-smell, taste, vision, hearing, equilibrium-in complex sense organs
order~bipolar~in olf.epithelium<sup. nasal cavity>exposed knob shaped dendrite, axon project
through cribriform plate and end in olf bulb. Respond to stim of ordorant by produce gener potent, intiating olf
response. Convey impulse to R/L nerves<I>, olf bulbs, olf tracts, cerebral cortex, limbic.
Olf Hairs: site of transduction:conversion of stimulus energy into a graded potential in a sensory receptor.
Support cells:epi. of mucus memb. lining nose. Give supp.nourish.elect.insulat.detox chem.
Basal stem cell:produce new olf. receptors. Between supp.cells. Constant divide.
Olf Glands: produce mucus, carried by ducts, to dissolve odorant
Adaption:Quick. Threshold: low
Sour, sweet, bitter, salty, unami
Gust receptor cells in taste buds on soft palate, tongue, pharynx, epiglottis. Convey impulse to nerves 7, 9, 1O. Nerves
carry from recept to medulla, thalamus, and pariet lobe of cerebral cortex.
Taste buds<epi> consist of supp, gust receptor, basal. Found in papillae
