1. What is the physiological function of this reflex? Explain how this reflex may be important during walking, if you are clumsy like me and did not notice a hole in the sidewalk and stepped into it.2. What is the role of reciprocal inhibition?3. How would the reflex be affected if reciprocal inhibition failed?4. Describe the effects on the reflex of severing each structure involved in the reflex, considering one structure at a time.

With regard to the Knee Jerk Reflex: What is the physiological function of this reflex? Explain how this reflex may be important during walking, if you are clumsy like me and did not notice a hole in the sidewalk and stepped into it. What is the role of reciprocal inhibition? How would the reflex be affected if reciprocal inhibition failed? Describe the effects on the reflex of severing each structure involved in the reflex, considering one structure at a time.

1. Formulate a hypothesis about the sequence of events that occur in the nervous system during: a) Knee Jerk b) Achilles Reflex c) Babinski reflex d) Pupillary reflex 2) How does the knee jerk reflex change when a person is clenching a book in their hands? Why do you think this is? 3) What is the purpose of testing different reflexes? 4) Explain why the knee jerk and Achilles reflexes are important in walking. 5) A person touches a stove, withdraws his or her hand, and then yells. Why does the yelling occur after the hand is withdrawn? Does the person become aware of the pain before the hand is withdrawn? 6) While examining the victim of a serious car accident, a physician lightly pokes the patient with a needle. The pokes begin near the ankle and gradually progress toward the knee. Why is the physician poking the patient? Why begin near the foot?

1) Describe the neural pathway involved in the Achilles tendon reflex 2) Describe the neural pathway involved in the Patellar tendon reflex. 3) The reflex times for the Achilles Tendon Reflex and the Patellar Tendon Reflex should be different? Why? 4) The conduction velocities for the Achille's tendon reflex and the Patellar tendon reflex should be similar. Why?
