A neurotransmitter is a chemical which carries the nerve impulse from the end point of a nerve cell to the dendrites of the next nerve cell.
A hormone is a chemical substance which is secreted by an endocrine gland directly into the blood stream or plasma in which it travels to a specific target organ and brings about a change in them.

What weighs twice as much as a brain?
A human liver typically weighs twice as much as a human brain.
Which two neurotransmitters regulate the brain's response to new information and unusual situations?
Glutamate and dopamine are the two neurotransmitters that play a key role in regulating the brain's response to new information and unusual situations. Glutamate is involved in learning and memory, while dopamine is associated with motivation and reward processing, both of which are important for adapting to new and unexpected stimuli.
What is the two main part of the body?
brain and heart
What are the two neurotransmitters that axon terminals of autonomic neurons release?
The two main neurotransmitters released by the axon terminals of autonomic neurons are acetylcholine and norepinephrine. Acetylcholine is predominantly released by parasympathetic neurons, while norepinephrine is released by sympathetic neurons.
What are two main organs of the central nervous system?
The brain and the spinal cord are the two main organs of the central nervous system. The brain is responsible for processing information, while the spinal cord is involved in transmitting messages between the brain and the rest of the body.
What are the two main groups in the human body and why?
the heart and the brain
What two brain neurotransmitters are affected by gambling?
Serotonin and Dopamine.
What is excitatory messages?
There are two kinds of neurotransmitters - INHIBITORY and EXCITATORY. Excitatory neurotransmitters are not necessarily exciting - they are what stimulate the brain. Those that calm the brain and help create balance are called inhibitory. Inhibitory neurotransmitters balance mood and are easily depleted when the excitatory neurotransmitters are overactive.
What are two ways the drugs affect the brain chemistry?
increases and decreases the amount of neurotransmitters
Where is language localized in the human brain?
There seem to be two main areas where language functions are processed in the brain, Broca's Area and Wernicke's Area.
What cells remove neurotransmitters from receptor sites?
Astrocytes and microglia are two types of glial cells that help remove neurotransmitters from receptor sites in the brain. They play a crucial role in maintaining the balance of neurotransmitters in the synapse by clearing excess neurotransmitters and preventing overstimulation of the neurons.
What are the two natural painkillers produced in the brain called?
The two natural painkillers produced in the brain are endorphins and enkephalins. They are neurotransmitters that help to reduce pain and promote feelings of well-being and relaxation.

What is the function of a neurotransmitter?
NEUROTRANSMITTERS are the brain chemicals that communicate information throughout our brain and body. They relay signals between nerve cells, called "neurons." The brain uses neurotransmitters to tell your heart to beat, your lungs to breathe, and your stomach to digest. They can also affect mood, sleep, concentration, weight, and can cause adverse symptoms when they are out of balance. Neurotransmitter levels can be depleted many ways. As a matter of fact, it is estimated that 86% of Americans have suboptimal neurotransmitter levels. Stress, poor diet, neurotoxins, genetic predisposition, drug (prescription and recreational), alcohol and caffeine usage can cause these levels to be out of optimal range.There are two kinds of neurotransmitters - INHIBITORY and EXCITATORY. Excitatory neurotransmitters are not necessarily exciting - they are what stimulate the brain. Those that calm the brain and help create balance are called inhibitory. Inhibitory neurotransmitters balance mood and are easily depleted when the excitatory neurotransmitters are overactive.
How does information travel through the small space between neurons in the brain?
Information travels through the small space between neurons in the brain through chemical messengers called neurotransmitters. When an electrical signal reaches the end of one neuron, it triggers the release of neurotransmitters into the synapse, the gap between neurons. These neurotransmitters then bind to receptors on the neighboring neuron, transmitting the signal and allowing communication to occur between the two neurons.
