NEUROCHEMICALS Meaning and
Definition
-
Neurochemicals refer to chemical substances that are involved in the communication and functioning of the nervous system. They are responsible for transmitting signals between nerve cells (neurons), influencing neural activity, regulating mood, behavior, and various bodily functions. These chemicals play a crucial role in maintaining homeostasis and coordinating the intricate network of the nervous system.
Neurochemicals are typically produced and released by neurons, and they act as messengers or neurotransmitters between these cells. They are involved in the transmission of electrical impulses across synapses, the tiny gaps between neurons, allowing information to be relayed throughout the nervous system. Some well-known examples of neurochemicals include dopamine, serotonin, norepinephrine, and GABA (gamma-aminobutyric acid).
These substances not only facilitate the transfer of signals but also contribute to the regulation of emotions, mood, cognition, and other physiological processes. Imbalances or abnormalities in neurochemical levels can have significant impacts on mental health and neurological disorders. Therefore, understanding the role and function of neurochemicals is crucial in various fields, including neuroscience, psychiatry, and pharmacology.
In conclusion, neurochemicals are chemical substances involved in the transmission of signals and the regulation of various physiological processes within the nervous system. They play a fundamental role in communication between neurons and are essential for the overall functioning of the brain and body.
Common Misspellings for NEUROCHEMICALS
Etymology of NEUROCHEMICALS
The word "neurochemicals" is a compound word that combines two primary components: "neuro" and "chemicals".
1. "Neuro" is derived from the Greek word "neuron", meaning "nerve". It denotes anything related to the nerves or the nervous system.
2. "Chemicals" comes from the Greek word "khēmeia", which originally referred to the process of transmuting base metals into gold. Over time, it evolved to signify the study of substances and their properties, eventually referring to substances with specific characteristics. In modern language, "chemicals" refers to any substance with a distinct composition and properties.
When combined, "neurochemicals" refers to substances or compounds that have a specific chemical composition and play a role in the functioning and communication within the nervous system.
