control of saliva secretion Flashcards
what does a conditioned salivary response mean?
learned, acquired by association
what does an unconditioned salivary response mean?
unlearned, innate
describe mechanical stimuli
unconditioned, pressure on PDL/oral mucosa
describe chemical stimuli
unconditioned, gustation, olfaction, common chemical sense
describe gustation
receptors on taste buds; tongue dorsum,palate and epiglottis, dif potencies- acis most, bitter least
describe olfaction
receptors in olfactory eptithelium, very weak stumulus
describe common chemical sense
primitive response to irritants, eg spicy, mediated by nociceptors in mucous membranes
describe conditioned stimuli
learned responses to psychic, visual, auditory stimuli
how do parasympathetic nerves control salivation?
increase secretion and vasodilation
how do sympathetic nerves control salivation?
increase secretion and vasoconstriction
