The nervous system is a complex network of cells, tissues, and organs that coordinate and control the body's responses to internal and external stimuli. It is composed of two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS).
The CNS includes the brain and the spinal cord, while the PNS includes all the other nerves in the body. The nervous system is responsible for sending and receiving signals throughout the body, allowing us to sense and respond to our environment.
The nervous system can be further divided into two main types of cells: neurons and glial cells. Neurons are specialized cells that transmit electrical and chemical signals, while glial cells support and protect the neurons. Together, neurons and glial cells form the functional units of the nervous system, which are responsible for transmitting information throughout the body.
The nervous system is involved in many essential functions, such as controlling movement, regulating bodily functions like heart rate and breathing, processing and interpreting sensory information, and enabling cognitive functions like memory and learning.
There are many different disorders that can affect the nervous system, including:
Treatment for nervous system disorders depends on the underlying cause and the severity of the condition. Medications, surgery, and physical therapy may be used to treat various nervous system disorders.
