Document Summary
Filiform (small/conical, carpet no taste buds), fungiform (larger, round), Foliate (leaf, on upper edges), vallate (circles form inverted v) Gustatory pathway: tongue/taste bud receptors-sensory nerve fibers > nerves 7, 9, 10. > (solitary nucleus of medulla > thalamus) > cerebral cortex in insula (from projection/receptor inward) olfactory cilia > apical dendrite (of olfactory neuron) > bundles of axon filaments (of neuron) > cribriform plate > olfactory bulbs & synapse w/ mitral cells (output) in glomeruli (clusters) (from mitral cells ) > limbic system & piriform lobe (of cerebral/olfactory cortex, w/hook uncus) Conjunctiva (transparent mucous membrane) w/palpebra & bulbar conjunctiva, conjunctival sac. Lacrimal gland (produce fluid/tears) > excretory ducts of lg > lacrimal punctum & canaliculus > lacrimal sac (fluid empties) > (down) lacrimal sac > nasolacrimal duct > inferior meatus (drainage) 6 extrinsic eye muscles (o: walls of orbit ( annular ring for 4 rectus muscles), i: outer surface of eyeball, specific cranial nerves control/innervate.
