When the electrical potential in a cell is in action versus a resting state the electrical charge reversal?
Action Potential
Do axons carry action potentials away from the cell body?
The areas that have had the action potential are refractory to a new action potential.
Dendrites conduct both graded and action potential?
no, dendrites and cell bodies can only have graded potential. action potential only occurs in axons
What is the electrical signal carried by a nerve cell?
Action potential
Immediately after a action potential has peaked which cell gate opens?
sodium channels close and potassium channels open
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.
Which cell conducts an action potential?
neurons
What cell that generates action potential?
neuron
When the electrical potential in a cell is in action versus a resting state the electrical charge reversal?
Action Potential
Do axons carry action potentials away from the cell body?
The areas that have had the action potential are refractory to a new action potential.
Dendrites conduct both graded and action potential?
no, dendrites and cell bodies can only have graded potential. action potential only occurs in axons
What is a T-tubule?
To carry an action potential to the interior of the cell.
What is the electrical signal carried by a nerve cell?
Action potential
Immediately after a action potential has peaked which cell gate opens?
sodium channels close and potassium channels open
Where does potassium diffuse to after an action potential is propagated?
Out of the cell into the tissue fluid.
An action potential is caused by an influx of these ions into the cell?
sodium ions
In which direction do potassium ions flow as the action potential passes?
Out of the cell
