Leak channels and sodium-potassium pumps are present on the cell body, dendrites, axon and terminal ends of the neuron cell membrane.

a. true
b. false

True

Explanation:

The neuron has leak channels in the cell body, axon and dendrite and cell body. This is because the trans membrane potential exists in all parts of the cell membrane.

Because of this reason the the leak channels are available at each part of the neuron.

The action potential, trans membrane potential should exits in all the parts of the cell so it should be located in all the parts of cell.
