GENERAL SENSES

a more localized stimulation would indicate that there are

parallel pathways

what part of the brain is responsible for motor control

precentral gyrus

what part of the brain is responsible for sensory control

postcentral gyrus

what type of neurons would go into the posterior gray matter horn

unicellular

true or false: free nerve endings are surrounded by tissue

false

what does a smaller receptive field indicate towards

more axons/receptors in a given area

which body part has the smallest receptive field

fingertips

what causes nerve adaptation

hyperpolarization

what structure in the brain filters out irrelevant stimuli

thalamus

what receptors do not undergo adaptation

pain receptors

what receptor got activated during the two-point discrimination test

tactile/meissner

what receptor would get stimulated by deep vibrations

lamellar

what exteroceptor would get stimulated by constant deep pressure

bulbous

what interoceptor is embedded in elastic tissue

baroreceptors

what is the conversion of environmental stimuli to nerve impulses called

transduction

what structure would be found in proprioceptors

muscle spindle

what do muscle spindles detect

minute extension of sensory nerve endings

what do nerve impulses require to go to the somatosensory association areas

further differentiation

why do pain receptors not adapt

they are protective in nature (adaptation would lessen necessary external awareness/sensitivity)

what occurs when general sensory receptors become less sensitive to a sitmulus overtime and stop inducing nerve impulses

adaptation

what nerve ending detects pain

free nerve ending

where are nerve impulses first relayed to

postcentral gyrus

when pain is perceived in an area separate from where the area that is actually receiving that pain stimulus, this is called what

referred pain
