Chapter 16 Flashcards
(52 cards)
sensory receptors provide information about
external and internal environments
receptors main purpose is to respond to
stimuli
stimuli helps us maintain
homeostasis
photorecetors respond to
light energy
hair cells respond to
sound waves
transducers convert
stimlus energy to elercrical
ion gated channels (voltage gated)
how to transducers convert energy
by changing resting membrane potentions by opening gated channels
what ions are involved in converting stimuli
sodium, potasium, calcium
send electrical signals down nerves using
ion gated channels
how many types of general receptors are there
2
what are the types of general sense receptors
somatic sensory receptors, visceral sensory receptors
somatic sensory receptors
skin and mucous membranes; proprioceptors of joints muscles and tendons
visceral sensory receptors
found in walls of internal organs, they monitor stretch, chemical environment, temp, and pain
special sense are specialized and comprised in sense organs in the
head
5 special senses
olfaction, auditory, gustation, vision, equilibrum
caterization by stimulus origin
exterorecptors, interreceptos, proprioceptoes
exterocepots
detect stimuli from external environment
interoceptors
detect stimuli from internal organs
proprioceptors
detect body and limb movements
categorization by mdality of stimulus(stimulus agent) relates to what 5 types
chemoreceptors, thermoreceptors, photoreceptors, mechanoreceptors, and nociceptors
chemoreceptors detect
chemicals dissolved in fluid
thermoreceptors detect changes in
temperature
chemoreceptors can include receptors for _________ or ______
external environment or internal environment
