plzz define Nervous system and define the parts...

dont copy from google...​

Answer 1

Answer:

The nervous system in a human is made of the brain, spinal cord, sensory organs and all the neurons that serve as communication channels between the various organs of the body. It is primarily made of a single type of cell called the neuron. Colloquially, they are also called nerve cells. Neurons are made of a central cell body and a number of extensions. The cell body is also known as the soma, and extensions can be either dendrites or axons.

Usually, smaller extensions close to the soma are known as dendrites, and as a general rule, they are adapted to receive stimuli. Many neurons have one (and occasionally more than one) long axon that can be over a meter long. Axons can contain a lipid covering called the myelin sheath that helps the neuron transmit electrochemical messages quickly towards another neuron or an effector cell

Bundles of neuronal axons are called nerves or tracts, depending on their location. Specialized cells called glial cells, whose role includes the production of myelin and the supply of oxygen, usually support neurons. Glial cells are also important in providing mechanical support and protection from pathogens.

Neurons can form connections with each other to create circuits and networks that influence learning, perception, behavior, and even create predictable physiological responses to external stimuli.

Answer 2

Answer:

a system of the body that in vertebrates includes the brain, spinal cord, nerves, and sense organs and receives, interprets, and responds to stimuli from inside and outside the body. nervous system.
