|
conscious awareness of stimuli received by receptors
|
sensation (perception)
|
|
|
the second step to sensation is "within the CNS, nerve tracts convey action potentials to the CEREBRAL CORTEX and to other areas of the CNS.
|
true
|
|
|
the area monitored by a single sensory neuron
|
receptive field
|
|
|
type of sense that aknowledges (information about the body and environment) touch, pressure, temperature, proprioception, pain
|
somatic
|
|
|
type of sense that aknowledges pain and pressure, chemical
|
visceral
|
|
|
type of sense that detects smell, taste, sight, hearing, balance
|
special senses
|
|
|
special senses are called ____ ____
|
secondary receptor
|
|
|
sensory receptor classified by stimulus type that detects damaged cells producing chemicals that stimulate these special receptors that we associate with pain _______.
|
nociceptors ; bradykinins
|
|
|
sensory receptor classified by location that it sensitive to stimuli coming from musculoskeletal structures; degree of stretch; muscles, tendons, joints, ligaments, connective tissue coverins of bones and muscles.
|
proprioceptors
|
|
|
simple modified dendritic endings of sensory neurons are split into two groups which are:
|
unencapsulated, encapsulated
|
|
|
unencapsulated: myelinated?
|
unmyelinated
|
|
|
found nearly everywhere especially in epithelial & connective tissue
|
unencapsulated
|
|
|
small diameter of unencapsulated simple neurons allows for what?
|
smaller receptive field
|
|
|
detects pain, temperature, tissue movements; itch histamine or bradykinins
|
unencapsulated
|
|
|
almost all encapsulated are mechanoreceptors
|
true
|
|
|
ex of encapsulated is meissner's and pacinian
|
true
|
|
|
allows body to know how far it can stretch each muscle.
|
muscle spindles
|
|
|
strength of sensory stimulus affects the ____ of impulse transmission
|
frequency
|
|
|
which receptors cause release of neurotransmitters that bind to receptors on a neuron causing a receptor potential? (smell, taste, hearing, balance)
|
secondary
|
|
|
decreased sensitivity to a continued stimulus? (penny on skin after a while you forget its there?)
|
accommodation (adaptation)
|
