Sensory receptors transduce _______________ and transmit signals to the _____________.
stimulus energy, CNS.
Action potentials that reach the brain via sensory neurons.
The awareness and interpretation of the sensation. ie: colors, smells, sounds, and tastes.
What does sensory reception begin with?
The detection of stimulus energy by sensory receptors.
Detect stimuli originating outside of the body.
Detect stimuli originating inside the body.
The conversion of stimulus energy into a change in membrane potential.
A sensory receptor's version of a graded potential.
The strengthening of stimulus energy so that it can be detected by the nervous system. It may occur separate from or with sensory transduction.
The conduction of sensory impulses to the CNS.
The _________ of the stimulus and receptor potential affects the __________________ released by the sensory receptor.
strength, amount of neurotransmitter
The ___________ of the receptor potential affects the ___________ of action potentials.
What are 5 types of sensory receptors?
Mechanoreceptors, pain receptors, thermoreceptors, chemoreceptors, and electromagnetic receptors.
A decrease in responsiveness to continued stimulation (continuous stimulation does NOT mean that there's a continuous transmission!)
