What types of ion channels are most important for conduction of a nerve impulse?

What’s another name for an unmyelinated nerve fiber?

1..All of the following statements about initiation and transmission of action potentials in neurons are correct EXCEPT: a)The rate of transmission of an action potential is directly related to the diameter of the axon. b)Information about the intensity of a stimulus is conveyed by changes in the size of the action potential generated. c)The resting potential is maintained by differential ion permeabilities and the sodium-potassium pump. d)Once initiated, local depolarizations stimulate a moving wave of depolarization down the axon. e)A stimulus to the neuron can either depolarize or hyperpolarize the neuronal membran 2.. Neurotransmitters that affect a neuron's response to other neurotransmitters are called _______. 3.. The key substances that create an action potential are protein channels that move —- out of a cell and —-into a cell. 4.. A cell with a membrane potential of -80 milivolts is? 5.. A gland secreting its product is an example of the —- 6.. If the charge inside…
