Why Are Neurotransmitters Important - Assignment Example

Response to of my mate about their neurotransmitters. What do you think about their answer? nu# 1Meza Why are neurotransmitters important? There are many nerve cells in the body. Each cell is different and produces different neurotransmitters. The brain is composed of chemicals that contribute and work based on where these neurotransmitters are located. Therefore, neurotransmitters are the chemicals that allow communication via signals from one neuron to the other. Going back to the “cause and effect”, once neurotransmitters are released (cause) a specific action (effect) is expected. In my understanding it could be the physical and emotional results of the body. Student nu 2 Dominguez neurotransmitters are chemicals that send signals and impulses from one neuron to another cell. these chemicals are made in the cell body form there they are transported to the end of the neuron. once there they are enclosed in vessels where they are soon made into or released to the neuron membrane. these neuron are very important to the to our role in both learn and behave. These neuron are important in some voluntary movement. These neutron can also he linked to mental illness or mental health. Certain neurons control the way we act in certain situations. These definitions are not the complete definitions and therefore do not provide the information required.

Neurotransmitter is a chemical substance which is synthesized, stored, released on receiving action potential, metabolized, degraded and re- up taken and acts on pre- and post-synaptic receptors. They act as chemical messengers between neurons and relays information. Neurotransmitters are important because they are involved in transmission of impulses between neurons and from neuron to other body cells as only neurotransmitters can pass through synaptic space and neuromuscular junction.
