    Spinal Cord
  3. What is the meningeal layer that adheres to the surface contour of the brain?
    Pia Mater
  4. What is the name tract of the white mater that connects the hippocampus with the hypothalamus?
  5. What is the smooth surface that covers the brain, but does not follow the underlying neural convulsions and/or sulci?
    Arachnoid Mater
  6. How are the functions of CNS as you ascend from the medulla oblongata to the cerebrum?
  7. What is the cranial reflex that is often used to test the sensory function of the trigeminal nerve?
  8. What is the name of the fold Dura mater that projects between hemispheres?
    Falx Cerebi
  9. What is the nerve that innervates the voluntary swallowing muscle?
    Spinal Accessory Nerve
  10. Diffusion across the arachnoid villi returns CFS to which circulation?
    Venous Circulation (sinus)
  11. Function of the limbic system:
    • - establishing emotional states
    • - linking the conscious intellectually functions of the cerebral cortex with the unconscious and automatic functions of the brain stem
    • - facilitating memory storage and retrieval¬†
    • - known as the motivational system
  12. Function of the nuclear gracilis:
    - rely somatic sensory information to the thalamus
  13. How the internal capsule of cerebrum is composed:
    It is composed of sensory fibers, which is a small region that is tightly packed with axons; the internal capsule connects the cortex with the thalamus & with the spinal cord
  14. Which of the nerves when damaged could result in death?
    C-10 Vagus
  15. What is an important aspect of ANS?
    The part of the nervous system of vertebrates that control involuntary actions of the smooth muscles, heart and glands; it makes routine homeostatic adjustments in physiological system; it works without interference of the conscious mind (increase and decrease daily activity)
  16. Functions of ANS?
    • - coordinates cardiovascular, respiratory, digestive, urinary and reproductive functions
    • - it adjusts internal body fluids without interference of the conscious mind (control all the daily activity)
  17. What are the visceral reflexes?
    An automatic motor response that can be modified, facilitated, or inhibited by higher centers, especially those of the hypothalamus (internal organs- vomiting, arousal, ejaculation, coughing, etc.)

    Hypoglossal C-12
  19. What is the state of unconsciousness in which an individual cannot respond to stimuli?
  20. Where the center of the reticular activating system is located:
    mid-brain: mesencephalon

    Vagus nerve
  22. What is the other name for cranial division?
    Parasympathetic division
  23. Beta-blockers drugs are used to treat which pathology?
    high blood pressure/hypertension
  24. What are the brain waves that are characteristics in children and frustrated adults?
  25. Which organs are innervated by the celiac ganglions?
    digestive system
