The central nervous system (CNS) consists of the brain and spinal cord. It is responsible for processing and coordinating sensory input and motor output. The CNS plays a crucial role in controlling most functions of the body, including thoughts, emotions, and movements.
The peripheral nervous system (PNS) consists of all the nerves outside the CNS that connect the CNS to the rest of the body. It is responsible for transmitting sensory information to the CNS and carrying motor commands from the CNS to the muscles and glands.
Flow Chart Of Cns And Pns
Flow chart of PNS:
1. Sensory input is received by sensory receptors in the skin, muscles, and organs.
2. Sensory input is transmitted through sensory neurons to the CNS.
3. Motor commands are sent from the CNS through motor neurons to muscles and glands.
4. Motor commands are executed by muscles and glands, producing movement and other responses.
Key Differences Between CNS and PNS
While both the CNS and PNS play critical roles in the functioning of the nervous system, they have distinct functions and structures. The CNS is the control center of the nervous system, while the PNS is responsible for connecting the CNS to the rest of the body. Understanding the flow chart of the CNS and PNS can help in grasping how sensory input is processed and motor commands are executed in the body.
