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.

An impulse travels down the axon of a neuron as an electrical signal known as an action potential. When this action potential reaches the end of the axon, it triggers the release of neurotransmitters into the synapse. These neurotransmitters bind to receptors on the next neuron, causing a new action potential to be generated in the receiving neuron.

The neurotransmitters of a neutron enable a nerve impulse to do what?
Neurotransmitters in a neuron allow a nerve impulse to be transmitted from one neuron to another by crossing the synapse and binding to receptors on the receiving neuron. This triggers an electrical or chemical signal to continue the nerve impulse along the neural pathway.
Space through which a nervous impulse is transmitted from one neuron to another?
The space through which a nervous impulse is transmitted from one neuron to another is called a synapse. It is a tiny gap between the axon of one neuron and the dendrite of another, where neurotransmitters carry signals across the gap to continue the message.
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 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.
What happens at the synapse between two neuron?
At the synapse, the electrical impulse between the two neutrons at synapse set of chain chemical reactions which create a chemical impulse at the synapse.

What is a true statement about synapses?
Synapses are specialized junctions between two neurons where communication occurs via neurotransmitters. They play a crucial role in transmitting electrical or chemical signals in the nervous system. Synaptic strength can be modified through processes like long-term potentiation or depression, affecting overall neuronal communication and plasticity.
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.
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.
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.
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 is specialized to carry out its function through its structure and composition. Nerves are made up of bundles of nerve fibers that transmit electrical impulses. They are surrounded by connective tissue layers that provide support and protection. Nerves also contain specialized cells called glial cells that support and insulate the nerve fibers.
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 ions are responsible for triggering the fusion of neurotransmitter vesicles with the axon's membrane during the conduction of a nerve impulse. The influx of calcium ions into the neuron's terminal triggers the release of neurotransmitters into the synaptic cleft.
