The human nervous system is a complex network of specialized cells (neurons) that transmit signals throughout the body. It can be broadly divided into two main parts:
Central Nervous System (CNS):
The CNS includes the brain and the spinal cord.
The brain is responsible for processing information, controlling voluntary and involuntary actions, and regulating bodily functions.
The spinal cord serves as a communication pathway between the brain and the rest of the body.
Peripheral Nervous System (PNS):
The PNS consists of nerves that extend from the CNS to various parts of the body.
It includes sensory nerves (which carry information from sensory organs to the CNS) and motor nerves (which transmit signals from the CNS to muscles and glands).
The PNS also has autonomic nerves that regulate involuntary functions like heart rate, digestion, and breathing.
