___ nociceptors are unmeylinated
thermal/mechanical noiceptors are assocaited with ___ pain
sharp, prickling pain
polymodal nociceptors are assocaited with
with high intensity mechanical, chemical, hot, and cold stimuli.
Nociceptive specific neurons are found in___of the spinal cord
nocipceptive specific neurons have ___ receptor fields
nocieptive specific neurons carry
only info about noceipcetion
. Wide dynamic range neurons (WDR) are found in ___ of the spinal cord
Wide dynamic range neurons carry information
from both mechanoreceptors and noiceptors
Wide dynamic range neurons have ___ receptor fields
. hyperalgesia is what happens when you have increased sensitivity to the ____.
surrounding unharmed region of a damaged area
with hyperalgesia Subsequent stimuli result in the
enhanced sensation of pain
referred pain is the result of a ____
lack of nociceptive output neurons in the dorsal horn that are dedicated to visceral pain
dissociated sensory loss is when you have reduced sensation of epicritic sensation in the opposite side of the body from where you have ___.
reduced sensation of temperature and pain
Pain modulation can occur as the result of the descending pathway synapsing with
an opiate containing interneuron
The opiate containing interneruon synapses with the ascending pathway in the dorsal horn releasing enkephalin that dampens
both presynaptic and postsynaptic neurons

lgn cells are binocular or monocular?
monocular.. they have functional segregation
