Furley's Lectures

1. 1Reflexes are:

   1. ARapid
   2. BSterotyped
   3. CInvoluntary
   4. DSlow
   5. EAlways voluntary
   6. FDifferent each time
   7. GUsually involve muscle contraction and/or glandular responses
2. 2Is the patellar reflex monosynaptic or polysynaptic?

   1. AMonosynaptic
   2. BPolysynaptic
3. 3Which of the following statements are correct regarding the stretch (myotactic) reflex?
   
   i) It is a response to pain in the knee
   ii) It is important in maintaining posture
   iii) It is part of the proprioceptive system
   iv) The sensory receptor that detects the muscle stretch is the Muscle spindle

   1. AIf ii), iii) and iv) are correct
   2. Bif i) and ii) are correct
   3. Cif ii) and iii) are correct
   4. Dif all are correct
4. 4Which is the sensory afferent for Golgi tendon organs?

   1. AIa
   2. BIb
5. 5The Golgi tendon reflex is a positive feedback circuit

   1. ARichtig
   2. BFalsch
6. 6The flexor (withdrawal) reflex results from the activation of which sensory receptors?

   1. ANociceptive
   2. BProprioceptive
7. 7is the flexor (withdrawal) reflex a monosynaptic or polysynaptic reflex?

   1. Amonosynaptic
   2. Bpolysynaptic
8. 8In both the stretch and withdrawal reflexes, inhibitory interneurones are activates to relax extensor muscles.

   1. ARichtig
   2. BFalsch
9. 9The process in which inhibitory interneurones are activated to relax extensor muscles is called:

   1. Areciprocal inhibition
   2. Blateral inhibition
10. 10Which of these receptors are slowly adapting?

    1. AMeissner (or tactile) corpuscles
    2. BPacinian (or lamellated) corpuscles
    3. CRuffini corpuscles
    4. DMerkel (or tacticle) discs

11. 11Which of the following is correct about rapidly adapting (phasic) receptors?

    1. AThey give information about changes in the stimulus
    2. BThey continue to respond as long as stimulus is present -> gives information about persistence of stimulus
12. 12Pain fibres have a quicker conduction velocity than proprioceptors?

    1. ARichtig
    2. BFalsch
13. 13The Medial Lemniscal tracts carry which signals to the thalamus?

    1. Amechanoreceptive
    2. Bproprioceptive
    3. Cpain
    4. Dtemperature
14. 14The area of the cortex occupied by the different body parts are proportional to their physical size.

    1. ARichtig
    2. BFalsch
15. 15If the receptive fields are small, discrimination is high?

    1. ARichtig
    2. BFalsch
16. 16Which fibres are associated with pain? (ie. are nociceptors)

    1. AA-alpha
    2. BA-beta
    3. CA-delta
    4. DC
17. 17Both the spinothalamic and medial lemniscal tracts preserve topography.

    1. ARichtig
    2. BFalsch
18. 18Painful stimuli activate the same region of the somatosensory cortex as non-painful stimuli when stimuli is applied to the same area of skin

    1. ARichtig
    2. BFalsch
19. 19Huntington's disease is due to the degeneration of the.. ?

    1. Asubstantia nigra
    2. Bstriatum
20. 20Parkinson's leads to:

    1. Ahyperkinesis
    2. Bhypokinesis
