Nervous System

The nervous system is a complex network of specialized cells that transmit signals between different parts of the body. It consists of two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS includes the brain and spinal cord, while the PNS includes all the other nerves in the body. The nervous system plays a vital role in controlling and coordinating body functions, including movement, sensation, perception, and thought. It is responsible for regulating bodily processes such as breathing, heart rate, digestion, and hormone release. The nervous system is also involved in responding to external stimuli, such as touch, light, sound, and smell. Dysfunction of the nervous system can lead to a variety of neurological disorders, including Parkinson’s disease, Alzheimer’s disease, multiple sclerosis, epilepsy, and stroke. Treatments for these disorders may include medications, physical therapy, and surgery.
