How is an impulse transmitted from one neuron to the next?
Beandumbo
Neurons communicate primarily in two ways: (1) electrical communication and (2) chemical communication. Neurons communicate electrically using gap junctions between neurons where electrical impulses are sent directly from one neuron to another. This is method is used for local communication as the electrical signal degrades over larger distances. Neurons communicate chemically using chemicals called neurotransmitters which are ejected from one neuron into a space between neurons (called the synapse) and are then absorbed or taken up by other neighboring neurons.

Space through which a nervous impulse is transmitted from one neuron to another?
The synaptic gap, also called the synapse.
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 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.
Which ion causes neurotransmitter vesicles to fuse with the axon's membrane during the conduction of a nerve impulse from one neuron to the next?
calcium
What is a true statement about synapses?
The synaptic cleft prevents an impulse from being transmitted directly from one neuron to another.
What is a presynaptic neuron?
a neuron from the axon terminal of which an electrical impulse is transmitted across a synaptic cleft to the cell body or one or more dendrites of a postsynaptic neuron by the release of a chemical neurotransmitter.
Space through which a nervous impulse is transmitted from one neuron to another?
The synaptic gap, also called the synapse.
If an impulse traveled down one neuron but failed to move on to the next neuron what happened to the first neuron?
Vesicle are not fusing with the membrane and releasing neurotransmitter.

These neurotransmitters then bind to receptors on the adjacent neuron, allowing the impulse to be transmitted indirectly.
Why is a neuron called an interneuron?
A neuron is called a inter-neuron because that specific neuron takes impulse from one neuron to a next neuron. For example your sensory neuron sends a impulse that you had felt a hot object. It goes through the spine to a inter-neuron to a motor neuron (this processes is called a reflex). Then the motor neuron tells your muscles in your hand to move
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).
How is the message caried from one neuron to another it there is a space between them?
The synaptic gap is the space between the dendrites of one neuron and the axon of the next. The impulse is carried across this space by chemicals called neurotransmitters which conduct the electrical impulse.
How is a nerve specialised to carry out its function?
A nerve cell is called a neuron. The neuron has dendrites that receive impules from the previous neuron and send it to the cell body and an axon that transmits the impulse to the next neuron. There is a space between one cell's axon and the next cell's dendrites called a synapse. Neurotransmitters are released from the axon terminal to carry the impulse across the synapse.
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.
