The point at which two neurones meet is called the synapse. At this point there are 2 situations:
1: there is no gap, the neurones are physically connected by gap-junctions. This is a rarer situation but does occur. In this case the nerve impulse continues down the second neurone (known as the post-synaptic nerve)
2: there is a small gap (a few micrometers) between the cells. In this case the first nerve, carrying the impulse, (pre-synaptic) causes a release of a chemical known as a neurotransmitter. There are various types of neurotransmitters and each are involved in different situations. When the neurotransmitter reaches the 2nd nerve it binds to the membrane (in most situations) which either causes the cell to depolarize and continue the impulse, or causes hypo-polarization which prevents any other nerve stimulating it.
Short and Simple Answer:
Nerve impulse is transmitted by:
- nerve impulse triggers transmitter substance
- which diffuses across synapse
- the transmitter substance binds with receptor molecule in membrane of next molecule

What is the name of the region where two neurons are in done contact is known as?
synapse is that junction through which impulse can be transmitted from one neuron to another.
Functional connection between two neurons is a?
functional connection between two neurons is the transmission of electrical signals from one neuron to another through a synapse. When an electrical impulse reaches the axon terminal of the pre-synaptic neuron, it triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the post-synaptic neuron, allowing the electrical signal to be transmitted and continue the communication between neurons.
What transmits impulse between sensory and motor neurons?
Nerve impulses are transmitted between neurons via neurotransmittors that are released into the synapse by the sending neuron. The neurotransmittor then binds to a receptor on the receiving neuron; when enough receptors are triggered, an action potential is initiated on the receiving neuron.
What is the direction of impulse for motor neurons?
The direction of impulse for motor neurons is away from the brain.
Is it correct that synaptic clefts prevents an impulse from being transmitted directly from one neuron to another?
Yes, that is correct. The synaptic cleft is a small gap between neurons, and it prevents direct transmission of impulses. When an impulse reaches the end of a neuron, it triggers the release of chemical messengers called neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the adjacent neuron, allowing the impulse to be transmitted indirectly.
What is affector neurons?
these have one or more receptors that detect change in either the external or internal environment, information that is detected is transmitted as an electrical impulse to the CNS by the affector neuron.
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 type of nervous tissue that conducts a nerve impulse?
Neurons
What is a message that travels through a neurons?
An Impulse
What is impulse conduction is fastest in neurons?
Impulses that travel along myelinated neurons are the fastest.
Transmission of an impulse between neurons depends primarily on?
The transmission between neurons depends on the number of neurotransmitters that are present. If there aren't enough transmitters, the impulse is not passed into the second neuron, meaning it's cut down. If there are enough, it leads to an action potential (nerve impulse) in the second neuron. The nerve system is a rather confusing, and very technical, system in the body.
How an impulse can continue to travel along a nerve pathway when there's a gap between two neurons?
Nerve pathways are slim, however neurones are small in size therefore the total amount of atoms in the impulse is enough to fit through a gap in the pathway of neurons
