A neuron has an altered charge potential?
Depolarized
Does a neuron become depolarized during an inhibitory postsynaptic potential?
False
What is involved in action potential?
also known as the "nerve impulse". with stimulus the permeability of the membrane to NA+ at the point of stimulation increase, and NA- ions rush into the cell causing the outside to lose its excess of positive ions. That location becomes depolarized only for an instant, and this produces an action potential.
Organelle that required large number of cells whose membrane often depolarized?
Mitochondrion
What potentials are short-livedlocal changes in membrane potential that can be either depolarized or hyperpolarized?
Graded Potentials
How is nerve impulse conducted along a myelinated nerve fiber?
In non-myelinated axons, the nerve impulse is going to be produced when the action potential accross a membrane makes a wave of depolarization followed by a wave of repolarization. With the absence of the myelin, the impulse is transmitted continuously throughout the membrane. In a non-myelinated nerve, once an end of the cell, the dendrite, is depolarized, the depolarization a.k.a., the action potential, moves along the nerve membrane, and the area of membrane immediately behind the depolarized section becomes repolarized.
What is a neurons charge when it is depolarized?
-70 millivolts
A neuron has an altered charge potential?
Depolarized
What happens when a neurons is above its threshold level?
its depolarized.
What is a cell that is more positive than at rest is called?
depolarized
What are the three main states of a neuron?
polarized, depolarized, repolarized
A wave pattern travels down the length of the axon of a cell?
Depolarized

When a sodium channel opens and sodium rushes into a myocyte the cell membrane becomes?
