Chapter 17. The Anatomical Organization of the Central Nervous System

  1. The substantia nigra is part of the:
    1. Medulla
    2. Pons
    3. Midbrain
    4. Diencephalon
  2. The suprachiasmatic nucleus, part of the hypothalmus, is involved in
    1. Feeding behavior
    2. Circadian rhythms
    3. Growth
    4. Maternal behavior
  3. Cells in primary visual cortex are responsive to highly complex information, such as the shape of a face.
    1. True
    2. False
  4. Human beings have more cortical information-processing ability than rhesus monkeys primarily because
    1. Human cerebral cortex is thicker
    2. Human pyramidal neurons are more functional
    3. Humans have more cortical columns (modules)
    4. Humans have more white matter
  5. The insular cortex is closest to the
    1. Opercular cortex
    2. Cingulate cortex
    3. Uncus
    4. Calcarine sulcus
  6. Cerebral neocortex has how many layers?
    1. Three
    2. Five
    3. Six
    4. Seven
  7. Thalamic inputs to neocortex primarily end in which cortical layer?
    1. Layer II
    2. Layer IV
    3. Layer V
    4. Layer VII
  8. Large pyramidal cells in motor cortex projecting to spinal cord are found in which layer?
    1. Layer II
    2. Layer IV
    3. Layer V
    4. Layer VI
  9. Basket cells use which of these neurotransmitters?
    1. GABA
    2. Glutamate
    3. ACh
    4. Norepinephrine
  10. This distinctive six-layered structure  is called the
     
    a. Inferior colliculus
    b. Amygdala
    c. Lateral lemniscus
    d. Hippocampus

Chapter 18. The Functional Organization of Perception and Movement

  1. How many pairs of spinal nerve roots are there in humans?
    1. Eight
    2. Twenty-five
    3. Thirty
    4. Thirty-one
  2. Somesthetic fibers from the body synapse in the
    1. Ventral posterolateral nucleus
    2. Ventral posteromedial nucleus
    3. Medial lemniscus
    4. Medial dorsal nucleus
  3. The medial geniculate body is concerned with
    1. Vision
    2. Touch
    3. Hearing
    4. It shows no concern
  4. Subcortical structures projecting to the cerebral cortex project first to thalamus, then to cortex, with the exception of
    1. Dentate nucleus
    2. Emboliform nucleus
    3. Globus pallidus
    4. Olfactory bulb
  5. The primary sensory cortex contains not just one, but four complete topographic maps of the skin surface
    1. True
    2. False
  6. Multimodal association cortex is primarily concerned with
    1. Relaying information
    2. Fine discriminatory sensations
    3. Production of a unified percept
    4. There is no good hypothesis for its function at present
  7. The human corticospinal tract contains approximately
    1. Ten thousand axons
    2. One million axons
    3. One billion axons
    4. One jillion axons
  8. The human corticospinal tract (answer like an anatomist)
    1. Decussates in the medulla
    2. Decussates near the ventral horn cells it innervates
    3. Both
  9. The human corticospinal tract (answer like a clinical neurologist)
    1. Decussates in the medulla
    2. Decussates near the ventral horn cells it innervates
    3. Both
  10. The corticospinal tract is particularly important for
    1. Individuated finger movements
    2. Walking
    3. Grasping
    4. Chorea
