explain the whole process of nervous system
Answers
The nervous system is the organ system consisting of the brain, spinal cord and sense organs (such as the nose, skin and ear), as well as the nerve fibers that connect these organs with the rest of the body. Its primary roles are sensing changes in the environment (like your hand on a hot pan), integrating or processing all of this incoming information (''This is damaging our skin!''), and responding in the form of a motor reaction (''Move your hand immediately!'').
The Nervous System Is Made of Nerve Cells
The nervous system and all of its organs, including the brain, spinal cord and nerves fibers, consist of specialized nerve cells called neurons. Neurons have the unique ability to communicate with each other through the transmission of electrical impulses. The basic structure of a neuron is composed of a cell body, an axon (wrapped in myelin) and dendrites.
