Physiology 2

Front 1

process where sensory receptors respond to environmental stimuli by changing ion conductance:

Back 1

transduction, this process forms the first step in the encoding of info for transmission to CNS. Reflects the transformation of one form of energy into another and enables sensory receptors to serve as translators

Front 2

six types of receptors

Back 2

1) mechanoreceptors. 2) chemoreceptors. 3) thermoreceptors. 4)photoreceptors. 5) nociceptors. 6) Baroreceptors

Front 3

receptors that respond to extremes of any form of energy, which may cause tissue damage

Back 3

nociceptors - Pain!

Front 4

in transduction where various energy forms are transformed into electrical energy in the form of action potentials, action potentials carry information in regards to (3):

Back 4

kind of stimulus, location of stimulus in relation to body, intensity

Front 5

the region of the neuron involved in energy transduction

Back 5

namely the modified dendrites and cell bodies

Front 6

region of neuron involved in initiation of action potentials

Back 6

axon hillock

Front 7

transduction area does not contain voltage-gated Na+ channels, instead it contains:

Back 7

modality-gated channels that open or close based on a specific modality and produce local, graded receptor potentials

Front 8

two ways nervous system is able to analyze info from action potentials:

Back 8

frequency and recruitment
