31.3 The Peripheral Nervous System- The Sensory Division
1. Which nerves go through openings in the skull and stimulate the head and neck?___________	
2. What are ganglia?
	
3. What is the function of the sensory division of the peripheral nervous system?
	
4. What are sensory receptors?

Match the sensory receptor with the stimuli to which it responds

Sensory Receptor 	Stimuli
	  5.  chemoreceptor	A.  light
	  6.  mechanoreceptor 	B.  touch and pressure
	  7.  pain receptor 	C.  temperature changes
	  8.  photoreceptor 	D.  tissue injury
	  9.  thermoreceptor 	E.  chemicals 

The Motor Division
For Questions 10–12, write True or False on the line provided.
	    10.	The motor division of the peripheral nervous system transmits impulses directly from the sensory receptors to muscles or glands.
	    11.	The somatic nervous system regulates body activities that are under conscious control.
	    12.	Brain impulses are carried to motor neurons and then to muscles.
13. Complete a flowchart showing the reflex arc that occurs when you step on a sharp object.

Sensory receptors react to a stimulus and send an impulse to sensory neurons.

14. Complete the concept map.

Peripheral Nervous System

15. What is the function of the autonomic nervous system?
	
16. How might the autonomic nervous system prepare your body during rigorous exercise?

17. What is the function of the parasympathetic nervous system?

18. What situation might trigger a response from the sympathetic nervous system? Explain.
