Term
, posterior root
-axons synapse in post grey horn (bc psuedounipolar, cell bodies of
sensory neurons will be located in dorsal root ganglion)
-sensory - post horn, dorsal root
-motor - anterior "motor" horn, ventral root
# of open channels
ion size
# of gated channels
w rhodopsin
-use cells in nerual layer to create AP
-at rest - dark condition, rod cells unstimulated, constant release of NT
glutamate - produces IPSP > hyperpolarization in bipolar cells - no AP is
produced so single can't go to optic nerve
-witha. light stimulus - AP releases NT towards ganglion cell which creates AP for
optic nerve
A. Large diameter, myelinated, conduct at 12-130 m/s
-motor neurons > skel musc + most sensory neutrons
-fastest
B. medium diameter, lightly myelinated, 3-15 m/s
-ANS
C. small diameter, unmyelinated, <2 m/s
-ANS
