subconsious
somatic stimuli
visceral stimuli
special senses
vision hearing taste smell equalibrium
somatic senses
touch-pressure
temp
pain
proprioception
somatic stimuli
muscle length tension
visceral stimuli
blood pressure pH levels lung inflation osmolarity of blood fluids temp blood sugar
sensory systems
transduce incoming stimuli into an electrical signal
mechanosensitive receptors
respond to mechanical enegy
thermoreceptors
respond to changes in temp
chemoreceptors
respond to chemicals
taste and smell
electromagnetic receptors
responds to light of electromagnetic fields
vision and electromagnetic fields
nociceptors
responds to noxious stimuli
pain (tissue damage)
properties of the receptor potential
frequency of action potentials generated
number of receptors activated
duration of stimulus
simulus duration
tonic receptors
phasic receptors
tonic receptors
constant response
transmit signal to CNS as long as stimulus us present
slow to adapt
pressure-sensetive baroreceptors, nodeceptors, some tactile and propioceptors
