Region of brain for fine movement, balance, and muscle tone?6. Region of the brain that included the midbrain, pons, and medulla oblongata7. A single deep groove that separates the cerebrum into left and right hemispheres.8. Large regions of the cerebrum that correspond with skull bones.9. Thick folds of the brain separated by shallow grooves?10. Shallow grooves of brain that outline the gyri.11. Deep lateral groove that separates the cerebrum from cerebellum.12. Gray matter of the cerebrum = ____________.13. White matter of the cerebrum = ____________.14. The largest white matter area of the brain that connects the left/right hemispheres?15. Smaller white matter that connects hippocampus to hypothalamus?16. ___________ produces melatonin that helps regulate sleep cycles.17. THE relay center of the brain for all motor & most sensory synapses?18. What is the only sensory function that does NOT synapse in the thalamus?19. Name of the “memory bank” of the brain?20. The major control center for the endocrine system, autonomic nervous system, and survival behaviors?21. Multi-region area of brain that puts emotional context into sensory output (includes parts of temporal/frontal cortex, thalamus, & hypothalamus 22. Gland of brain that produces up to 9 different hormones including Growth Hormone (GH) & Thyroid Stimulating Hormone (TSH).23. White mater of the cerebellum that is referred to as “tree of life”?24. Clear liquid of Central Nervous System (CNS) that provides a cushion between brain andskull?25. Chambers that hold Cerebral Spinal Fluid (CSF) in brain?26. ____________________ are the largest ventricles forming and arc in each hemisphere.27. ____________ ventricle that receives the CSF from lateral ventricles and intersects the thalamus.28. ____________ ventricle is a triangular shaped chamber between pons and cerebellum that tapers into the central canal of spinal cord.29. ______________________ connects the 3rd and 4th ventricles.30.
