A neuron is the fundamental building block of the nervous system. Think of it as a specialized "messenger" cell designed to transmit information throughout your body using electrical impulses and chemical signals.
Unlike most cells, neurons don't just sit there—they are part of a massive, high-speed biological circuit that controls everything from your heartbeat to your deepest thoughts.
Anatomy of a Neuron
To understand how they work, it helps to look at their unique structure, which is built specifically for communication.
* Dendrites: These are the "antennae." They receive incoming signals from other neurons and carry them toward the cell body.
* Soma (Cell Body): The command center. It contains the nucleus and maintains the cell’s health and function.
* Axon: A long, tail-like cable that carries the electrical impulse away from the cell body toward other neurons or muscles.
* Myelin Sheath: An insulating layer of fat wrapped around the axon. It acts like the rubber coating on a wire, allowing signals to travel much faster.
* Axon Terminals: The exit points. This is where the electrical signal is converted into a chemical message to jump to the next cell.
How They Communicate
The magic happens at the synapse, the tiny gap between two neurons.
* Electrical Phase: An electrical pulse called an action potential travels down the axon.
* Chemical Phase: When the pulse hits the terminals, it triggers the release of neurotransmitters (like dopamine or serotonin).
* The Jump: These chemicals float across the synapse and "unlock" receptors on the next neuron, starting the process all over again.
Fun Fact: Speed and Scale
* Speed: Nerve impulses can travel at speeds of up to 120 meters per second (about 270 mph).
* Quantity: Your brain contains roughly 86 billion neurons, forming trillions of connections. If you lined them up, they’d stretch for miles!

PRINCIPLE OF HOMOGENEITY

➨ The magnitude of a physical quantity may be added or subtracted from each other only if they have the same dimension, also the dimension on both sides of an equation must be same.This is called as principle of homogeneity.

Dimensional Variables

➨ Dimensional variables are those physical quantities which have dimensions and do not have fixed value.

❖ E.g., velocity, acceleration, force, work, power... etc.

Dimensionless Variables

➨Dimensionless variables are those physical quantities which do not have dimensions and do not have fixed value.,

❖ E.g., Specific gravity, refractive index, Coefficient of friction, Poisson’s Ratio etc.,
