What else can I help you with?
Where are the leak channels located on a neuron and how do they contribute to the resting membrane potential?
Leak channels are located on the cell membrane of a neuron. These channels allow ions, such as potassium and sodium, to passively move in and out of the cell. This movement of ions helps to establish and maintain the resting membrane potential of the neuron, which is essential for its normal functioning.
State of an unstimulated neuron's membrane?
An unstimulated neuron's membrane is polarized, with a negative charge inside the cell relative to the outside. This resting membrane potential is maintained by the unequal distribution of ions across the cell membrane, particularly sodium and potassium ions. The neuron is ready to generate an action potential when stimulated.
What is another name for Nerve Cells?
Neuron is another name for a nerve cell.
What happens during an action potential in a neuron?
During an action potential in a neuron, there is a rapid change in electrical charge across the cell membrane. This change allows for the transmission of signals along the neuron.
Organisms or fluids attempting to enter the cell body of a neuron must first pass through the?
cell membrane, which acts as a protective barrier around the neuron. This selective barrier controls the passage of substances in and out of the neuron to maintain its internal environment.
What ions are positively charged and can cross back and forth across neuron and cell membrane?
There are two ions that can cross the cell membrane. The positively charged sodium and potassium ions can cross back and forth across the neuron cell membrane.
A name for a nerve cell is?
A neuron.
When a neuron is resting the inside of the cell membrane is?
When a neuron is resting, the inside of the cell membrane is more negative compared to the outside due to the unequal distribution of ions. This difference in charge is maintained by the sodium-potassium pump, which actively transports ions across the membrane to establish the resting membrane potential.

What is another name for Nerve Cells?
Neuron is another name for a nerve cell.
The basic smallest unit of the nervous system is _____which is cell, having nucleus and cell membrane?
Neuron
What is the name of the brain of the cell?
neuron
What is the name of a nerve cell?
Neuron
Another Name for the plasma membrane of?
the cell membrane
What does it mean when a cell is depolarized?
Depolarization refers to the reversal of charges of neuron cell membrane, it occurs by moving in of 'Na' ions .
What kinda ions are positively charged and can cross back and forth across the neuron cell membrane?
Positively charged ions like sodium (Na+) and potassium (K+) can cross back and forth across the neuron cell membrane through ion channels. These ions play a significant role in generating and propagating action potentials in neurons.
