Potential problems for our nerve cells are that, if you happen to have alot of nerve cells that die you could lose feeling in your chest. You could suffer a heart attack. Another problem for neurons is that their axons, which can be quite long, are not good electrical conductors. Although neurons and wires are both capable of passively conducting electricity, the electrical properties of neurons compare poorly to even the most ordinary wire.

What is the electrical potential across the cell membrane of a nerve cell or muscle cell when the cell is not active?
resting potential
Changes in the transmembrane potential of a cell are involved in?
nerve cell communication,thought, glandular secretion and movement.
How does a nerve cell make energy?
The part of the cell that produces energy varies between plants and animals. In plants, the energy producing part of the cell occurs in the chloroplast of the plant. In animals, the mitochondria produces the cells energy.
Is the longest cell the nerve cell of the giant squid?
The nerve cell is the longest cell in animals.
What composed of a cell bodydendritesand axon?
Nerve cell or neuron
What is the electrical potential across the cell membrane of a nerve cell or muscle cell when the cell is not active?
resting potential
What is the electrical signal carried by a nerve cell?
Action potential
How is a resting potential achieved in the nervous system?
The resting nerve cell is not being stimulated to send a nerve impulse
Changes in the transmembrane potential of a cell are involved in?
nerve cell communication,thought, glandular secretion and movement.
What is the medical term meaning Embryonic nerve cell?
The medical term for an embryonic nerve cell is a neuroblast. These are precursor cells that have the potential to develop into various types of nerve cells in the nervous system.
What is resting potential?
A rest potential is the potential difference between two sides of the membrane of nerve cells when the cell is not conducting an impulse. =)
What ion determines the resting membrane potential of nerve and muscle?
The concentrations on Na+ outside the cell and concentrations of K+ inside the cell determine the resting membrane potential.
Where is the hillock of the neuron?
The nerve cell hillock is the beginning of the axon immediately after the soma. This is where the action potential originates.
How does a nerve cell make energy?
The part of the cell that produces energy varies between plants and animals. In plants, the energy producing part of the cell occurs in the chloroplast of the plant. In animals, the mitochondria produces the cells energy.
What is impulse in the nervous system?
electrical wave conducted along the nerve generated by the voltage difference across the cell membrane of the nerve cells.
What is the job for the nucleus in a nerve cell?
It depends what part of the cell body you are talking about. The cell body of the nerve cell is the nerve cell. There is no difference between the two. Also, it depends what nerve cell you are talking about, it could be either a relay neurone, a motor neurone or a sensory neurone. The cell body of each is completely different.
What does a nerve cell have that a animal cell doesnt have?
Voltage-dependent-channels (these channels won't open until a critical electrical potential has build up)
