Answer:
Our nervous system consists of central nervous system and peripheral nervous system which work together and help us in sensing the surroundings.
Explanation:
The order of events are as follows:
1. Receptors (sense organs, muscles, glands, etc.) receive stimuli from the environment or from inside your body.
The first step is to receive the stimulus which is achieved by various sense organs with sensory receptors.
2. Information from receptors is sent to the spinal cord and brain by the peripheral nervous system (PNS).
PNS includes all the nerves of the body outside the brain and spinal cord. Once stimulus is received by the receptors the PNS helps to relay it to brain or spinal cord.
3. The central nervous system processes information received from the peripheral nervous system.
Once received the information is processed in the CNS and then again sent to the PNS. CNS receives information through the afferent nerves.
4. The central nervous system sends out the processed information to the peripheral nervous system.
The efferent nerves transmit information from CNS.
5. The peripheral nervous system sends a message to the body part that needs to respond so you can react appropriately to the stimulus.
Somatic nervous system relays the information to skeletal muscles whereas the autonomous nervous system relays the information to involuntary muscles.
