Neurons are specialized cells that transmit electrical and chemical signals throughout the brain and central nervous system, enabling communication between different parts of the body the central nervous system.
- Neurons are the electrically excitable cells that are the fundamental building blocks of the central nervous system of human beings.
- Neurons interconnect the systems and organs that maintain the body’s essential functions.
- Neurons send and receive signals that allow us to sense the external world, move, think, form memories and much more.
- Neurons are of three principal types: motor neurons, sensory neurons and interneurons.
- Neurons connect together via specialized filaments called synapses.
- In the neocortex (making up about 80% of the human brain), approximately 70-80% of nervous tissue is in the form of neurons whilst the remainder is composed of interneurons.
