Question

7. Trace the reflex arc, naming efferent and affercat nerves, receptors, effectors, and integration centers, for the two reflexes listed patellar reflex: Achilles reflex 8. Three factors that influence the rapidity and effectiveness of reflex arcs were investigated in conjunction with patellar reflex testing-mental distraction, effect of simultancous muscle activity in another body area, and fatigue. Which of these factors increases the excitatory level of the spinal cord? Which factor decreases the excitatory level of the muscles? When the subject was concentrating on an arithmetic problem, did the change noted in the patellar reflex indicate that brain activity is necessary for the patellar reflex or only that it may modify it? Name the division of the autonomic nervous system responsible for each of the reflexes listed. ciliospinal reflex pupillary light reflex: 9. salivary reflex: 10. The pupillary light reflex, the crossed extensor reflex, and the cormcal reflex illustrate the purposeful nature of reflex activ- ity. Describe the protective aspect of each. pupillary light reflex: corneal reflex: crossed extensor reflex 11. Was the pupillary consensual response contralateral or ipsilateral? Why would such a response be of significant value in this particular reflex?
