Five is wrong together in great numbers. Connects the brain and spinal cord with entire body. They are sensory nerves and motor nerves. Pick up information and send it up to brain.
What does sensory nerves do?
From parts to brain
What does motor nerves do?
From brain to parts
What is the reflex arc?
Nerve impulse from pain receptor goes up
Sensory neuron to spinal cord called cross section
Integration center called interneuron
Another impulse immediately goes down the motor neuron
To muscle which quickly moves the hand away from the pain.
Explain the reflex arc shortly.
Receptor Sensory neuron Integration center Motor neuron Effector
