It actively moves three sodium ions out of the cell and two potassium ions in, both against their concentration gradients

It passively moves three sodium ions out of the cell and two potassium ions in, both against their concentration gradients

It actively moves two sodium ions out of the cell and three potassium ions in, both against their concentration gradients

It passively moves three sodium ions out of the cell and two potassium ions in, both along their concentration gradients

None of these answers are correct

Axon

Dendrite

Soma

Nucleus

Sodium concentration is higher outside the cell because the pump drives sodium ions against their electrochemical gradient

Sodium concentration is lower outside the cell because the pump drives sodium ions against their electrochemical gradient

Sodium concentration is higher outside the cell because the pump drives sodium ions along their electrochemical gradient

Sodium concentration is lower outside the cell because the pump drives sodium ions along their electrochemical gradient

called a dendrite, and is often present in greater numbers on a single cell than the single axon

called a dendrite, and a neuron always has only one dendrite and one axon

called a dendrite, and uses ions different from the sodium and potassium used by axons to conduct signals

called a dendrite, and is always myelinated by Schwann cells

called a dendrite, and is always myelinated by oligodendrocytes

Increased ribosomal activity in the axon hillock

Increased mitochondrial activity in the axon

Lack of myelination in the soma

Decreased voltage-gated sodium channel density in the soma

Nodes of Ranvier distinct on the axon only
