Review Systems of the Human Body: Human body is made of ten different systems. All the systems require support and coordination of other systems to form a living and healthy human body

Definition of the nervous system The nervous system is the part of an animal that coordinates its actions by transmitting signals to and from different parts of its body. The nervous system detects environmental changes that impact the body, then works in tandem with the endocrine system to respond to such events.

Components of the nervous system The nervous system consists of two main parts: the central nervous system and the peripheral nervous system:

Work of the nervous system The nervous system is a network of cells called neurons which transmit information in the form of electrical signals. brain has around 100 billion neurons, and each communicates with thousands of. Neurons communicate with each other at special junctions where chemicals help to bridge the gap between one neuron and the next

Diseases affecting the nervous system Examples of Diseases affecting the nervous :system Epilepsy Shingles Stroke

Epilepsy Epilepsy is a group of neurological disorders characterized by epileptic seizures Epileptic seizures are episodes that can vary from brief and nearly undetectable to long periods of vigorous shaking

Shingles Shingles is a painful rash caused by the varicella-zoster virus, which is the same virus that causes chickenpox.

Stroke Stroke is a serious medical condition that occurs when the blood supply to part of the brain is interrupted
