Summary Introduction

Introduction:

Signals are transmitted from one neuron to another (or to the target tissue) at a specialized site between the two neurons where chemical signal molecules pass from one to the other.

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…
Which of the following is the role of axonal Calcium (Ca2+) channels in neuronal communication at the synapse? a) they inhibit the action potential causing it to stop b) Calcium channels have no role in this process c) by allowing calcium to exit the cell, they promote the propagation of action potential across the synapse by creating depolarization d) by blocking calcium entrance, they mediate the contraction of presynaptic axon to facilitate movement e) when they open, calcium enters the presynaptic terminal, promoting fusion of neurotransmitter vesicles with presynaptic membrane, and release of neurotransmitters to the synaptic cleft
How do neurotransmitters directly affect the postsynaptic neuron? A)They cause a change in the electrical potential, exciting the neuron and causing it to fire b)They cause a change in the electrical potential, either exciting or inhibiting the next neuron. C)They cause a change in the electrical potential, inhibiting the neuron and stopping it from fi d)They connect with the appropriate receptor on the postsynaptic neuron
