Ions involved in the action
potentials in neurons are cation (sodium and
potassium cations).
sodium ion enter the cell and potassium ion leaves the
cell.
Na+, the sodium ion moves
into neuron during the process of action potential.
the process of action potential
occurs when a neuron sends information to down axon and away from
the cell body. Action potentials are caused due to
different ions cross the neuron membrane.
A neuron that emits an action potential, or
nerve impulse, is called as "fire".Action
potentials which are generated by special
types of voltage-gated ion channels in a cell's plasma
membrane.
action potential is usually divided into five
parts: the rising phase, the peak phase, the falling phase, the
undershoot phase, and the refractory period.
