Answer The Following Questions:
1.Name the components of a mono- and poly-synaptic spinal reflex pathway, and describe generally how a reflex works.
2.Compare and contrast the structures and functions of the Golgi tendon organ and the muscle spindle.
3. Are relaxation of a muscle and inhibition of a muscle the same thing? Explain your answer.
4. Give a brief synopsis of CNS control of movement.
5. Your best friend, Fred, was injured when he fell several meters from a cliff, but his vital signs are stable and all lacerations have been repaired. His physician is in the process of
determining what neural damage he has sustained. What may be damaged if Fred is unable to walk normally? (Hint: Consider various types of factors that influence motor output, as well
as the structures immediately responsible for movement.)
6. What are the differential effects on the ANS of inhibiting the muscarinic vs. the nicotinic cholinergic receptors in the autonomic nervous system?
7. The Huaorani Indians of South America use blowguns to shoot darts poisoned with curare at monkeys. Curare is a plant toxin that binds to and inactivates nicotinic ACh receptors. What
happens to the monkey struck by one of these darts?
