Sensory input (Afferent)-Stimuli both and inside outside of the body
• Integration-From sensory input
• Motor output (Efferent)- Response to stimuli
The central nervous system is the the brain and spinal cord are the integration and command center
As the nerves spread down it spreads out like your fingers. another good example is your blood veins to capillaries. They just get smaller and smaller. They lead to neurons and axons. It is the areas where you receive amount of stimuli that sends messages up the nerve through your spinal cord to your brain and the action is received. Further action is taken from there as the brain sends a corresponding message
Such as if a athlete strained the muscle and caused deep pain for the body. The body does not perceive the pain at first due to the amount of adrenaline the body has coursing through the system. yet as the athlete cools down and relaxes after a hard workout or such, the axons and neurons from the nervous system can now pick up on minuscule pain points in the muscle. depending on the amount of pain the point can give off the athlete can be sore, as in the muscles feel fatigued and stretched, to a harsh pain that has the athlete, limping and hobbling. That would be the deep pain the muscle feels, but the body perceives it through the messages the brain receives from the neurons and axons.
Another form of deep pain can hardly be perceived in the body. Say for instance a person is thrown from a horse and suffers a broken spine or neck and survives the incident. He/she cannot feel the pain that the body is suffering because the connection to the brain via the spinal cord is severed. The nerves, axons, and neurons can be sending the messages, that the body is hurt and needs medical attention.
For the nervous system to actually work, it depends on the message system it has set up. Axon to neuron, to the spinal cord to the brain where the brain then sends the appropriate action to the message it has received.
random fact: nuns have larger neurons then regular people
