Signalling ALONG a neuron is electrical, but signalling BETWEEN neurons is a chemical process. Neuron A 'passes' a message onto the next by releasing chemicals called neurotransmitters , which are then taken up by neuron B.
The point at which these neurotransmitters are released from the neuron A is called the 'terminal bouton' and is the end of its axon. More specifically, it is the presynaptic membrane OF the terminal bouton at which the passing on of a message occurs.

The message that travels through a neuron?
A neural impulse. Specifically, once it fires, an action potential.
What do you call the state of a neuron when it is not firing a neural impulse?
Resting potential.
What is it called when another neural impulse cannot occur?
THe absolute refractory period
What is a neural transmission that bypasses the brain?
Reflex arc
A neural circuit where a single impulse is transmitted over and over?
it would be a reverberating circuit
What is neural impulse?
A neural Impulse is a spike of electrical activity.
Which is the correct sequence in the transmission of a neural impulse?
dendrite, cell body, axon, synapse
How are hormones similar to neurotransmitters?
A neural impulse is similar to an electrical signal in three ways: 1. there are electrical voltages involved in the movement of the neural impulse; 2. an electrical signal can convey information, as can a neural impulse; 3. an electrical signal can cause an action, like a car starter switch starting the engine, and a neural impulse can cause a muscle to contract to move a limb. (note that with respect to the voltages involved in the neural impulse, the voltages are created by the movement of chemicals, charged particles called ions, somewhat similar to how batteries produce voltages.) (also note that the neural impulse is the signal which moves along the axon, as an action potential.)
What are also called neural impulses?
Action potential is a neural impulse.
Are also called neural impulses?
Action potential is a neural impulse.
The message that travels through a neuron?
A neural impulse. Specifically, once it fires, an action potential.
What generate and transmit nerve impulse?
A sensory stimulus can generate a neural impulse, as can repeated or multiple inputs of neural signals from other neurons.A neural signal is transmitted from one neuron to anotheracross a synapse via chemicals called neurotransmitters, and a neural impulse is transmitted along an axon of a neuron by either an action potential (in an unmyelinated axon) or by saltatory conduction (in a myelinated axon).
What do you call the state of a neuron when it is not firing a neural impulse?
Resting potential.
What do you call the state of a neuron when it is firing a neural impulse?
Resting potential.
The state of the neuron when not firing a neural impulse is known as?
Resting potential
The speed at which a neural impulse travels is increased when the axon is encased by an?
myelin sheath
What is it called when another neural impulse cannot occur?
THe absolute refractory period
