Lecture 65: Gross Anatomy, Function and Blood supply of Brain - True False
True False Questions
1. White matter consists mostly of cell bodies, whereas gray matter consists mostly of myelinated axons.
2. Cerebral hemispheres are a characteristic of the brainstem.
3. The corpus callosum provides neural connectivity between the cerebral hemispheres.
4. Broca's area is located at the inferolateral region of the postcentral gyrus near the temporal (Sylvian) gyrus.
5. Primary motor cortex is anterior to the central sulcus (fissure of Rolando), whereas the primary sensory cortex is posterior to the central sulcus (fissure of Rolando).
6. Body walls having detailed motor and sensory function (hands) are represented by relatively larger areas of the motor and sensory homunculi than less complex body walls (thorax).
7. The arcuate fasciculus connects Wernicke's area to Broca's area.
8. Wernicke's area is predominantly involved with speech comprehension, whereas Broca's area is predominantly involved with speech production.
9. Primary visual cortex is located within the temporal lobe.
10. The insula primarily functions to initiate motor activity and is perturbed by Parkinson's disease.
11. The hypothalamus primarily functions to maintain homeostasis and, thus, plays upon the autonomic nervous system.
12. The thalamus primarily functions to relay sensory and motor information to other regions of the central nervous system.
13. The insula primarily functions to coordinate motor movements and reflexes.
14. The vertebral and external carotid arterial distributions provide the primary sources of arterial blood to the brain.
15. The cerebellum is primarily supplied by the vertebral arteries, whereas the cerebrum is primarily supplied by the external carotid arteries.
16. The anterior cerebral arteries are related to the longitudinal fissure, whereas the middle cerebral arteries are related to the temporal sulcus (Sylvian fissure).
17. The occipital cortex is primarily supplied by the anterior cerebral artery.
18. The circle of Willis provides an anastomosis between the anterior and posterior arterial circulation to the brain.
19. Superficial venous drainages of the brain primarily drain into the dural sinuses, whereas deep venous drainages primarily drain into the great cerebral vein of Galen.
20. The cerebellum has hemispheres and a central vermis.
