NERVOUS IMPULSE Meaning and
Definition
-
A nervous impulse refers to an electrical signal that generates and transmits information within the nervous system of an organism. It is a rapid, coordinated, and electrochemical communication process that enables the transmission of information between different parts of the body, including the brain, spinal cord, and peripheral nerves.
Nervous impulses initiate and propagate through the intricate network of neurons, which are the building blocks of the nervous system. These impulses are essential for transmitting sensory information, such as touch, taste, smell, sight, and sound, from the sensory organs to the brain. Furthermore, they are responsible for sending motor commands from the brain to the muscles and other organs, allowing for voluntary and involuntary bodily movements and functions.
The transmission of a nervous impulse relies on specific channels and receptors located on the membranes of neurons. When a nerve cell is stimulated, it undergoes depolarization, resulting in the rapid influx of sodium ions. This influx creates an electrical charge difference across the neuron's membrane, known as an action potential. The action potential then travels down the neuron's axon, supported by the actions of specialized proteins called ion channels, which allow the selective passage of ions. This rapid and sequential depolarization and repolarization process enables the propagation of the nerve impulse along the neuron.
In summary, a nervous impulse serves as a means of communication within the nervous system, allowing for the transmission of sensory information and coordination of bodily functions.

Etymology of NERVOUS IMPULSE
The word "nervous" comes from the Latin word "nervus", which means "sinew" or "nerve". It was used to refer to the nerves in the human body. The word "impulse" comes from the Latin word "impulsus", which means "push" or "thrust". When these two words are combined, "nervous impulse" refers to the electrical signals that travel along the nerves in the body, carrying information and triggering responses.
