Here is the detail about Which one of the following best describes how neurons transmit. Neurons are the essential components of the nervous system. They transmit messages to one another in various ways. Neuronal communication is very necessary for the performance of the entire body. The neurons communicate through chemical messengers which are known as Neurotransmitters. They may also communicate through electrical signals that are known as an action potentials.

One of the following Best describes how neurons transmit:
There are different neurons present in the body associated with different functions. Here in this article, you will get to know the complete details of thenotificationn of neurons with each other. It is a complete process of transmitting messages from one end of the neuron that is axon to the terminal and different parts of the body.
What Are Neurotransmitters?
Some chemical messengers help in the transmission of messages between different neurons. These chemical messengers are known as neurotransmitters. They help in transferring the signals between different neurons in the body and also from neurons to muscles in the body.
Every action in our body is through a chemical message that is transferred through neurotransmitters in our brain. There are excitatory and inhibitory neurotransmitters that help in generating the process of action potential. Some neurotransmitters can affect only a limited number of neurons while some have the potential to affect and send messages to a large number of neurons.
Process of Transferring Information Between Neurons:
The neurotransmitters carry themess the thee rom from things f the neuron to another target cell. The target cell can be a muscle, a nerve cell, or any gland in the body. These neurotransmitters are present at the axon terminal of the neuron. Also, they are stored within the synaptic vesicles. Many neurotransmitters are present in the synaptic vesicles. There is a space known as the synaptic junction where neurotransmitters reach and send messages.
The neurotransmitters bind to specific receptors that are present in the target cell. After their binding with the specific receptor they produce an action usually an electrical signal is transmitted to the nerve cell or muscles. So excitatory, inhibitory, and modulatory actions are produced by neurotransmitters on the target cell. These help in transferring the messages from one neuron to another.
Action of Neurotransmitters:
The neurotransmitters exhibit different types of actions. These may be excitatory, inhibitory, or modulatory. It depends on the type of neurotransmitter that which action will they produce. Following are the changes that will be transmitted by neurotransmitters for the transfer of messages from one neuron to another.
Excitatory Neurotransmitters:
The excitatory neurotransmitters help in the excitement of neurons and the passing of messages to the next cell present there. The excitation is caused by the electric potential. Excitatory neurotransmitters include norepinephrine, epinephrine, and glutamate.
Inhibitory Neurotransmitter:
Their role is to prevent the messages from being passed to another cell. They block the transmission of chemical messages. Examples of inhibitory neurotransmitters are glycine, serotonin, and GABA inhibitors.
Modulatory Neurotransmitters:
These neurotransmitters are also known as Immunomodulators. They can cause changes in a huge number of neurons at the same time. They can also affect changes in the action of other types of neurotransmitters. These modulatory Neurotransmitters help in modulating the excitation and inhibition action of other neurotransmitters. The most common example of modulatory Neurotransmitters are Dopamine and Serotonin.
Types of Neurons For Transferring Information:
Different types of best describes how neurons transmit.
Afferent Neurons:
It is one of the types of neurons that are known as sensory neurons. They help in transmitting the messages received from the senses like touch, taste, smell, hearing,g overseeing. They also help in transmitting the messages or signals perceived from pressure, cold, or heat. Any sensory input that is received by the body is further transmitted to the central nervous system where it continue action and releases the signals to different parts of the body.
Efferent Neurons:
Efferent neurons are those that transfer messages to the muscles. These muscles are associated with the skeletal system of the body. These muscles are attached to ligaments and these neurons help in transferring information to these muscles.
Presynaptic Neuron:
The neurons that are responsible for sending messages to different parts of the body are called presynaptic neurons. They send messages via chemical messengers known as neurotransmitters. They are essential for transferring information between the central nervous system and different organs.
Postsynaptic Neurons:
The post-synaptic neurons are used to receive the information that is transmitted by presynaptic neurons through neurotransmitters. The presynaptic neurons transfer information to the post-synaptic ones and they then transfer information to different parts of the body.
Association Neurons:
Association neurons are also known as interneurons. These neurons are present between efferent and afferent neurons. They act as an interface between them in the CNS. These neurons are the reason how the body can respond to any signal simultaneously.
Conclusion:
Best describes how neurons transmit main process through which the neurons transmit information to each other and different parts of the body is through chemical messages or electrical potential. The primary method is through chemical messengers which are known as neurotransmitters. The neurotransmitters play a vital role in the body by transferring the information that is necessary for producing any action.
