question 67

Multiple Choice

The significance of the initial segment of axons is that

• A)Its threshold potential is higher than that of the cell body and dendrites
• B)Its threshold potential is lower than that of the cell body and dendrites
• C)Synapses close to it are more effective in influencing whether an action potential will be generated in that axon than are synapses farther away from the initial segment
• D)Both its threshold potential is higher than that of the cell body and dendrites and synapses close to it are more effective in influencing whether an action potential will be generated in that axon than are synapses farther away from the initial segment are correct
• E)Both its threshold potential is lower than that of the cell body and dendrites and synapses close to it are more effective in influencing whether an action potential will be generated in that axon than are synapses farther away from the initial segment are correct
