The Nerve Impulse

The nerve impulse, what is is

QuestionAnswer
The nerve impulse is an electrical signal that conveys information along a WHAT? neuron
The nerve impulse is called the WHAT? Action potential
There are 2 phases of an action potential. What are they? depolarization, repolarization
The inside of a resting neuron is more negative (- ) than the outside (+). This term refers to the electrical charge difference across the membrane of the resting neuron. Resting membrane potential
As long as the neuron is WHAT, no nerve impulse is being transmitted. The resting cell is said to be WHAT. The cell is quiet or resting. Polarized
When the neuronal membrane is stimulated, a change occurs in the cell's electrical state. When the cell membrane is stimulated, the inside becomes positive. As the inside of the cell changes from negative to positive, it is said to WHAT? depolarize
After depolarization, very quickly the inside of the cell again becomes negative. In other words, it returns to its resting state, or WHAT? Unless the cell WHAT it cannot be stimulated again. Repolarizes
