5 Matching Questions

  1. pia mater
  2. excitable
  3. thalamus
  4. descending tract
  5. spinal nerves
  1. a thin delicate and deepest meninges layer, directly on brain and spinal cord;
    "pious mother" or "tender mother"
  2. b motor commands (as action potentials) sent down spinal cord to muscles in white matter
  3. c brain's "sensory switchboard" in diencephalon (above brainstem);
    almost all sensory information goes through thalamus and directed to specific cortex regions; cortex also sends replies and motor commands to the cerebellum and medulla through thalamus;
    involved in consciousness and wakefulness (damage can cause coma)
  4. d 31 pairs of nerves arising from the spinal cord;
    named for location on vertebrae (8C, 12T, 5L, 5S, 1C);
    composed of 2 roots: dorsal and ventral
  5. e property of cell that it may create and conduct an electrical current when stimulated;
    eg, neurons & muscle cells
    aka "irritability and conductivity"

5 Multiple Choice Questions

  1. deep groove in brain
  2. large bundle of axons connecting neurons in both cerebral hemispheres
  3. midbrain, pons, and medulla oblongata;
    brain regions connecting "higher" brain regions and spinal cord
  4. most inferior portion of brain stem;
    regulates VITAL body functions, such as: heart rate, blood pressure, breathing, swallowing, and wakefulness, and consciousness
  5. excitable cell specialized for quick electrochemical communication; carries out the main functions of nervous system; fires action potentials
    aka nerve cell

5 True/False Questions

  1. longitudinal fissuredeep groove running from anterior to posterior dividing cerbrum into left and right hemispheres, connected by corpus callosum


  2. motor neuroncarry movement commands (as action potentials) from CNS to muscle cells via descending tracts;
    aka Efferent neuron ("Efferent Exits" brain)


  3. ascending tractbundles of axons sending sensory information "up" to CNS;


  4. autonomic nervous systembrain and spinal cord;
    fast communicating organ system; receives sensory input; controls homeostasis (often via endocrine system); controls motor output; center of all mental activity including thought, feeling, learning & memory, and consciousness; aka CNS


  5. epidural spacespace above dura mater
