How does the nervous communication differ from hormonal communication?
The human body has two communication systems that allow us to respond to any changes in our environment. The nervous system uses nerve impulses (electrical impulses) to react quickly to a stimulus . The hormonal system uses hormones to react slowly to a stimulus.
What is hormonal coordination?
The endocrine system secretes hormones into the bloodstream from glands throughout the body. Hormones produce an effect on specific target organs in the body. Combined Science. Coordination and control.
What is the difference between a hormone and a neurotransmitter?
The main difference between hormones and neurotransmitters is that hormones are produced in endocrine glands and are released into the blood stream where they find their targets of action at some distance from its origin whereas neurotransmitters are released into the synaptic gap by a terminal of a stimulated …
What hormone is also a neurotransmitter?
Norepinephrine also called noradrenaline is both a hormone, produced by the adrenal glands, and a neurotransmitter, a chemical messenger which transmits signals across nerve endings in the body.
What are the 4 types of neurotransmitters?

- Dopamine.
- Glutamate.
- Serotonin.

What is the most important neurotransmitter?
Glutamate: The most plentiful neurotransmitter found in the nervous system, glutamate plays a role in cognitive functions such as memory and learning.
What are the three major classes of neurotransmitters?
Based on chemical and molecular properties, the major classes of neurotransmitters include amino acids, such as glutamate and glycine; monoamines, such as dopamine and norepinephrine; peptides, such as somatostatin and opioids; and purines, such as adenosine triphosphate (ATP).
What is Cotransmission?
Cotransmission, defined here as the control of a single target cell by two or more substances released from one neuron in response to the same neuronal event, does occur in experimental situations. In such cases, coreleased substances might act on other targets or modulate the receptors for the main transmitter.
What class of neurotransmitter is dopamine?
Dopamine (DA, a contraction of 3,4-dihydroxyphenethylamine) is a neurotransmitter that plays several important roles in the brain and body. It is an organic chemical of the catecholamine and phenethylamine families.
