CHEMICAL SIGNAL Meaning and
Definition
-
A chemical signal refers to a substance or molecule that is produced within an organism and acts as a communication tool by transmitting information between cells or organisms. These chemical signals play a vital role in various biological processes, including cellular communication, coordination of physiological functions, and governing social behaviors.
Chemical signals can be classified into different types based on their origin and mode of action. Endogenous chemical signals are produced within an organism and include hormones, neurotransmitters, and pheromones. These substances are synthesized by specialized cells or glands and are released into the bloodstream or surrounding environment to reach their target cells or organisms.
Hormones are a type of chemical signal that regulates various physiological processes within an organism, such as growth, development, metabolism, and reproduction. They are typically produced by endocrine glands and travel through the bloodstream to exert their effects on specific target cells.
Neurotransmitters, on the other hand, are chemical signals that facilitate communication between nerve cells. They are released from the presynaptic terminal of a neuron and bind to receptors on the postsynaptic membrane, transmitting signals across the synaptic gap.
Pheromones are specialized chemical signals that are used for communication between individuals of the same species. They can elicit behavioral responses, such as marking territories, attracting mates, or signaling danger.
Overall, chemical signals are essential for coordinating and regulating various physiological and behavioral processes in organisms, allowing for effective communication and coordination between cells or individuals.

Etymology of CHEMICAL SIGNAL
The etymology of the word "chemical signal" can be broken down as follows:
1. Chemical: The word "chemical" comes from the Latin word "chemicus", which means "of alchemy" or "pertaining to chemistry". The Latin word itself originated from the Greek word "khēmíā", referring to the art of transmuting metals.
2. Signal: The word "signal" can be traced back to the Old French word "seignal" (later also spelled as "signau" or "seignel"), which means a "sign, mark, or token". It blends the Latin word "signum", meaning "sign" or "signal", and the Latin verb "narrare", meaning "to tell" or "to make known".
