When a neuron is polarized:
A)the exterior fluid surrounding the neuron is more negatively charged than the interior of the neuron.
B)an action potential will travel down the dendrites causing the release of neurotransmitters.
C)the electrical charge across the neuron's membrane is balanced with the same charge outside as inside.
D)the interior of the neuron's axon is more negatively charged than the exterior fluid surrounding the axon.

Question

Quizplus · Accepted Answer

When a neuron is polarized, the interior of the neuron's axon is more negatively charged than the exterior fluid surrounding the axon. This is due to an unequal distribution of ions, with more positively charged ions outside the cell and more negatively charged ions inside. This creates a potential difference across the membrane known as the resting membrane potential.
