Nervous system

The Nervous system is a complex network of neurons and cells that transmit signals between different parts of the body. It is essentially the body's electrical wiring and is responsible for controlling the body's functions and maintaining its homeostasis.

Structure[edit | edit source]

The nervous system is divided into two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord, while the PNS consists of all the other neural elements.

Central nervous system[edit | edit source]

The central nervous system is the main control center of the body. It receives information from the sensory organs, processes it, and then sends out instructions to the rest of the body.

Peripheral nervous system[edit | edit source]

The peripheral nervous system is a network of nerves that connects the central nervous system to the rest of the body. It is responsible for transmitting information between the CNS and the body's organs, muscles, and skin.

Function[edit | edit source]

The nervous system has three main functions: sensory input, integration, and motor output. Sensory input involves collecting information from the environment, integration involves processing and interpreting the sensory input, and motor output involves responding to the integrated stimuli.

Disorders[edit | edit source]

There are many disorders that can affect the nervous system, including neurodegenerative diseases, stroke, brain tumors, and spinal cord injuries. These can have a significant impact on a person's quality of life and ability to function.
