The nervous system is a complex and highly organized system that controls and coordinates all activities of the body. It receives sensory information from both the internal and external environment, processes and interprets this information, and then sends appropriate responses to muscles, glands, and organs.
Structurally, the nervous system is divided into the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which consists of cranial and spinal nerves. Functionally, it is further divided into the somatic nervous system, which controls voluntary actions, and the autonomic nervous system, which regulates involuntary activities such as heart rate, digestion, and respiration.
Overall, the nervous system maintains homeostasis, enables communication within the body, and allows humans to think, learn, remember, and respond to changes in their environment.
