ANSWERS
1. 42-45 CM
2. Pencil or finger
3. Foramen magnum to end of L2
4. Intervertebral foramen, vertebrae
5. True
6. Below
7. C8
8. Cervical, brachial, arms/forearms/hands
9. Lumbar, lumbosacral, thighs/legs/feet
10. Conus medullaris
11. Anterior aspect of the coccyx. It keeps the cord from moving superior.
12. Cauda equina, nerve roots
13. Sensory, motor, mixed. It means info can come in & go out.
14. Cervical = 8 pairs, Thoracic = 12 pairs, Lumbar = 5 pairs, Sacral = 5 pairs,
Coccyx = 1 (single) TOTAL = 30 pairs plus 1
15. Grey & white
16. Grey inside, white outside
17. Nerve cell bodies, interneurons
18. Fibre tracts & glia
19. Myelinated axons (tracts carrying info)
20. Horns/grey
21. Anterior, motor, motor
22. Posterior, sensory, sensory
23. Autonomic, internal organs
24. T1-L2 & S2-S4
25. Roots
26. False – They are made up of unipolar neurons
27. True
REFLEXES
28. Unconscious
29. False – they can not be improved. Work with what you/re born with.
30. 1)Segmental response rule: for every stimulus there is a reflex, and 2.) The brain
is always informed about what’s occurring.
31. D – all of them apply
32. Simple multisynaptic
33. Gray commissure, opposite
34. False – it is generalized
35. Complex
36. Multisynaptic, brain, variable, sensations & memories
37. True
38. 1)Facilitation, 2)increased amount/intensity of NT, 3)increase in srfc. area for
synapses, 4)growth of additional axon terminals
39. Variable, thinking
TRACTS
40. Spinal cord
41. Proprioception (to cerebellum) & smell (to frontal lobe)
42. True
43. Spinal cord or brainstem
44. Spinal cord (as well as pain & temperature), brainstem (2 point discrimination,
vibration)
45. Primitive, advanced
46. Anterior funiculus
47. Lateral. Lateral funiculus
48. Posterior columns, posterior funiculus, ipsi-laterally, medulla
49. Lower, upper
50. Somatic sensory
51. Spinocerebellar tract, proprioception
52. Frontal lobe
DESCENDING TRACTS
53. Corticopontine
54. Corticospinal, Pyramidal
55. Brain stem, corticospinal
56. Lateral is bigger, 80% of axons
57. Lateral/brainstem/contra (Anterior is all the others)
58. True
59. Basal ganglia, spinal cord
60. Extrapyramidal
Sensory System
61. One
62. Nociceptors
63. Electromagnetic
64. True
65. Mechanoreceptors & thermoreceptors
66. Whatever the type of stimulus, immediate effect is to change the potential across
the receptor membrane – called receptor potential.
67. 1)Mechanical deformation of the receptor 2)application of a chemical to the
membrane 3)change in temperature of the membrane 4)electromagnetic radiation
(light)
68. True
69. Receptor, receptor potential, threshold, action potential
70. Amplitude, receptor potential, frequency, receptor potential
71. Adaptation
72. High, lower
73. Tonic
74. Rate, movement, phasic, detect
75. A, larger, myelinated
76. Alpha, beta, gamma, delta
77. Half, peripheral, post-ganglionic
78. Group 1a
79. Group 1b
80. Group II
81. Group III
82. Group IV
83. Destination
SOMATIC SENSATIONS
84. Mechanoreceptive, thermoreceptive & pain
85. Mechanical displacement
86. Touch, pressure, vibration, tickle, position
87. Touch is stimulation of receptors just beneath the skin, whereas pressure results
from deformation of deeper tissues.
