The nervous system is divided into two main portions:
the central nervous system (CNS) and the peripheral nervous system.
The nervous system is divided into two main portions: the central nervous system (CNS) and the peripheral nervous system (PNS).
The central nervous system includes the brain and the spinal cord. It is responsible for processing and coordinating the sensory information received from the body and the environment, and then transmitting the appropriate motor responses back to the body.
The peripheral nervous system, on the other hand, consists of all the neural tissues outside the CNS, including the nerves that carry sensory and motor signals between the CNS and the rest of the body. The PNS can be further divided into two functional parts: the somatic nervous system (SNS), which controls voluntary actions such as moving your arms and legs, and the autonomic nervous system (ANS), which controls the body’s involuntary responses such as heart rate, digestion, and pupil dilation.
