2. What are the parts of the CNS? Brain & spinal cord




3. Describe something that you do on a regular basis that your PNS controls. uranation




4. What are the two divisions of the autonomic nervous system and what does each control?Sympathetic & para sympathetic. Controls body in stressful situations, brings body back to normal.




5. What are the three main types of neurons? What is the function of each? Sensory, motor, interneuron. recieve impulses from the body, tell you to react, transport impulse to the brain




6. What is the function of the axon of a nerve cell? The dendrite? impulses are sent from the axon and end up at the dendrite, synapse happens and it jumps to neuron.




7. What is a synapse? conduction of an impulse from one neuron to another.
