    • A) Hypothalamus
    • B) Thalamus
    • C) Pons
    • D) Corpus callosum

    • B) Cerebellum
    • C) Hypothalamus
    • D) Corpus callosum
  3. 3.

    • A) Medulla oblongata
    • B) Cerebellum
    • C) Thalamus
    • D) Midbrain
  4. 4.

    Both the brain and the spinal cord are enveloped by three protective connective tissue membranes known as the meninges. Which of the following layers is the innermost meninx that adheres directly to the surface of the brain and spinal cord?

    • A) Dura mater
    • B) Arachnoid mater
    • C) Subarachnoid space
    • D) Pia mater
  5. 5.

    Which statement correctly describes the anatomical arrangement of grey matter and white matter in the human cerebrum compared to the spinal cord?

    • A) In both the cerebrum and the spinal cord, grey matter is situated exclusively in the central core and is enveloped by an outer layer of white matter.
    • B) The cerebrum has an outer cortex of grey matter surrounding inner white matter, whereas the spinal cord has outer white matter surrounding an inner core of grey matter.
    • C) In both the cerebrum and the spinal cord, white matter forms the superficial layer while grey matter is completely restricted to deep internal nuclei.
    • D) The cerebrum possesses an outer layer of white matter surrounding central grey matter, whereas the spinal cord features outer grey matter surrounding central white matter.
