Lab Practical Chapter 20: Reflexes
front 1  In your diagram above, how many synapses of the reflex arc are found in the CNS? Is the reflex monosynaptic or polysynaptic | back 1 There should be two synapses in the CNS the reflex is polysynaptic |
front 2 if the motor neuron in the diagram is a somatic motor neuron, what must the effector be | back 2 skeletal muscle |
front 3 Which of the following terms apply to the patellar reflex? (Circle the ones that apply.) monosynaptic or polysynaptic cranial or spinal somatic or autonomic ipsilateral or contralateral | back 3 monosynaptic spinal somatic ipsilateral |
front 4 Can you consciously control your quadriceps muscles? | back 4 yes |
front 5 Do you consciously control your quadriceps muscles during the patellar reflex | back 5 no |
front 6 What happened to the response when the seated person was naming bones? | back 6 There should have been a stronger response (a more pronounced kick). this may or may not have actually been observed. |
front 7 The brain may send inhibitory signals to the neurons involved in a reflex. Distracting the brain with a task like naming bones may remove theşe inhibitory signals. Given this information, what should happen to the response when the seated person is naming bones? | back 7 If inhibitory signals are removed, then there should be a stronger response |
front 8 Which of the following terms apply to the withdrawal reflex? | back 8 polysynaptic somatic spinal ipsilateral |
front 9 Which of the following terms apply to the crossed-extensor reflex? | back 9 polysynaptic somatic spinal contralateral |
front 10 Can you consciously control the diameter of your pupils? | back 10 no |
front 11 Which of the following terms apply to the pupillary reflex? | back 11 polysynaptic, autonomic, cranial, and ipsilateral and contralateral responses both occur |
front 12 Can you identify another autonomic reflex? (Hint: Think of food.) | back 12 salivating in response to the smell of food, another is contractions of smooth muscle of the esophagus during swallowing |
front 13  How many neurons are in a monosynaptic reflex? | back 13 2 |
front 14 Is this reflex monosynaptic or polysynaptic? | back 14 polysynaptic |
front 15 Is this reflex ipsilateral or contralateral? | back 15 ipsilateral |
front 16 Is this a spinal reflex or a cranial reflex? | back 16 spinal |
front 17 Is this reflex autonomic or somatic? | back 17 somatic |
front 18 How many multipolar neurons are found in this reflex? | back 18 2 |
front 19 How many unipolar neurons are involved in this reflex? | back 19 1 |
front 20  Name the reflex being tested. | back 20 patellar reflex |
front 21 Is this reflex monosynaptic or polysynaptic? | back 21 monosynaptic |
front 22 Is this reflex ipsilateral or contralateral? | back 22 ipsilateral |
front 23 Is this a spinal reflex or a cranial reflex? | back 23 spinal |
front 24 Is this reflex autonomic or somatic? | back 24 somatic |
front 25 If a penlight is shined into an individual's left eye, then the diameter of his left pupil will... | back 25 decrease |
front 26 Is the pupillary reflex monosynaptic or polysynaptic? | back 26 polysynaptic |
front 27 Is the pupillary reflex a spinal reflex or a cranial reflex? | back 27 cranial |
front 28 Is the pupillary reflex autonomic or somatic? | back 28 autonomic |
