When a neuron is activated by a stimulus, it's plasma membrane instantly becomes permeable to Na+ so these ions quickly diffuse into the neuron as Na+ channels close, the inward flow of Na+ for a brief instant causes the inside of the plasma membrane to become positively charged and the outside to become negatively charged at the point of stimulation, this switch in polarity is called depolarization which is considered the nerve impulse... depolarization is quickly followed by repolarization, once the impulse reaches it's effector, the axon tip forms a synapse (junction) with either another a neuron's dendrites, a muscle etc. which then continues to either pass the impulse along or create an outcome in the target cell.

An electrical impulse moving down an axon is called what?
The nerve that travels down a neuron axon is basically Action Potential.It is an electrochemical change that passes through the cell.
What composed of a cell bodydendritesand axon?
Nerve cell or neuron
Synaptic vesicles are found in what?
Synaptic vesicles are found in the axon terminals of nerve cells.
Mechanism of nerve conduction?
Nerve impulses are conducted along the axon in the myelinated nerve fiber with causes the polarity of the nerve.
A nerve impulse starts at the dendrite then travels to the?
axon
How does a nerve impluse get transmitted along an axon full 5 pages length answer?
Write your own paper.
What is the space through which a nerve impulse passes from one nerve cell to another called?
A nerve impulse passes from an axon terminal of one neuron to another neuron across a synaptic gap.
What is the difference between a nerve dendrite and a nerve axon structurally?
The nerve axon is the main nerve from where the dendrites originate.
An electrical impulse moving down an axon is called what?
The nerve that travels down a neuron axon is basically Action Potential.It is an electrochemical change that passes through the cell.
Axon is what?
An axon (or axone) is a nerve fibre which is a long, slender projection of a nerve cell, which conducts nerve impulses away from the body of the cell to a synapse.
What composed of a cell bodydendritesand axon?
Nerve cell or neuron
What does the nerve cell include?
The nerve cell can be thought of as just the nerve body, which is the main part of the nerve cell. The nerve cell is also known as a neuron. The entire neuron includes an axon, nerve body, dendrites, and axon terminals.
What is the name of the area where nerve impulses arises?
receptive region?
Microscopic fiber that carries the nervous impulse along a nerve cell?
axon
How can you the word axon in a sentence?
The axon carries nerve impulses away from the cell body.
Synaptic vesicles are found in what?
Synaptic vesicles are found in the axon terminals of nerve cells.
Can a nerve fiber survive without its cell or its axon?
It can survive without an axon but not without its cell
