large, well-myelinated axonse. typically affects the axon at the ventral root
of the spinal cord..
Answer: d. typically affects Schwann cells of large, well-myelinated axons.
◍ The repolarization phase of action of action potentials in neurons is due
primarily to the flow of.

postsynaptic membrane. Answer: chemical
◍ -mostly in sensory components like the RETINA- associated with sensory
processing.
Answer: bipolar
◍ Functionally, which cellular location is the neuron's "decision-making site"
as to whether or not an action potential will be initiated?. Answer: the axon
hillock
◍ Schwann Cells.
Answer: produce myelin in PNS
◍ For a neuron with an initial membrane potential at -70, an increase in the
movement of potassium ions out of that neuron's cytoplasm would result in
the.
