Discover How the Human Nervous System Works

The Human Nervous System Explained

The human nervous system is a complex network of cells and organs that coordinates the body's actions by transmitting signals between different parts of the body. It is divided into two main parts: the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which connects the rest of the body to the CNS.

The nervous system is responsible for controlling everything from movement and sensation to thought and emotion. It allows the body to respond to stimuli and maintain homeostasis. Disorders of the nervous system, such as Parkinson's disease or multiple sclerosis, can disrupt these vital functions.

Did You Know?

• The brain contains approximately 86 billion neurons, which transmit electrical signals throughout the body.
• The spinal cord serves as the main pathway for communication between the brain and the rest of the body.
• There are two types of nervous system cells: neurons and glial cells.
• Neuroplasticity is the ability of the nervous system to reorganize itself by forming new neural connections.
