Across
  1. 1. Posterior part of the Proscencephalon (forebrain) containing the epithalamus, thalamus, metathalamus, hypothalamus, and the subthalamus
  2. 5. nervous system spends energy and prepares for fight or flight. In doing so constricts blood vessels, induces perspiration, dilates pupils, accelerates heart rate
  3. 7. Artery supplies most of the caudal third of the spinal cord. It is formed at the lower thoracic and upper lumbar level.
  4. 8. arteries arise in the circle of willis and are major arteries that supply external brain structures
  5. 10. is the site of interconnection between blood vessels. Also provides a system of revascularization in the brain collateral circulation in the case of vascular insufficiency.
  6. 11. tract regulates muscle tone for limb extension and posture in support of body against gravity. (sitting upright)
  7. 12. arteries arise in the circle of willis and are small arteries that penetrate the ventral surface of the brain to supply the internal and subcortical structures
  8. 15. The Midbrain connects the hindbrain and the forebrain
  9. 17. Nerves in the PNS have 12 pairs
  10. 21. nervous system conserves energy; dominant during relaxation or sleep; lowers heart rate, decreases body metabolism, constricts pupils
  11. 22. Cerebral Artery curves along the inferior brain surface to supply the temporal lobe, hippocampus, portions of the occipital lobe including the primary visual cortex.
  12. 25. mater is the outermost layer of the Meninges, attached to the surface of the skull; thickest and toughest layer; provides the most protection.
  13. 27. nervous system is an involuntary self-monitoring system regulated by the hypothalamus
  14. 29. the top of the horizontal plane and the back of the vertical plane
  15. 30. principle states that all primary sensory and motor regions in the cerebrum are connected through association and commissural fibers.
  16. 31. tract regulates neck and body twisting in response to visual and auditory stimuli (startle reflex – turn to look at something loud)
  17. 33. is a slowness of movement, including talking, walking or any voluntary movement.
  18. 35. fibers connect the two hemispheres of the brain.
  19. 39. roots contain efferent fibers and innervate skeletal muscle
  20. 40. cerebral artery damage results in contralateral hemiplegia, Impaired sensory functions of touch, tactile agnosia, reduced pain and temperature, aphasia, constructional deficits, homonymous hemianopsia, alexia and agraphia
  21. 41. Axonal fibers carry sensory impulses towards the CNS
Down
  1. 2. clinical symptoms present on the opposite side of the body to the lesion site
  2. 3. Carotid divides into the anterior cerebral and middle cerebral arteries
  3. 4. protects the central nervous system and consists of three layers
  4. 6. area of the brain that receive dual blood supply from large arteries.
  5. 9. Most anterior part of the Proscencephalon (forebrain) consisting mainly of the cerebral hemispheres
  6. 13. Sinus System is composed of Veins and sinuses collect deoxygenated blood and transport it back to the heart and lungs for reoxygenation.
  7. 14. spinal artery blood flow interruption results in hemiplegia and pain and temperature hemisensory loss (one side sensory loss).
  8. 16. Axonal fibers carry the commands away from the CNS
  9. 18. membrane is a thin membrane between the dura mater and pia mater in the Meninges
  10. 19. mater is a thin membrane attached to the surface of the brain in the Meninges that follows the contours of the sulci and gyri and surrounds blood vessels.
  11. 20. tract projects vestibular impulses to the spinal LMNs. Regulates extensor muscle tone to control the reflexive adjustments of the body and limbs and to keep the head stable.
  12. 23. system lifeblood of the nervous system; it provides oxygen and other nutrients to neural structures and removes waste from them. It is a major locus of abnormalities for motor speech disorders.
  13. 24. Hindbrain that develops into the metencephalon (pons and cerebellum) and mylencephalon (medulla oblongata)
  14. 26. fibers connect areas within the same hemisphere of the brain.
  15. 28. the front of the horizontal plane and bottom of the vertical plane
  16. 32. the back of the horizontal plane and the bottom of the vertical plane
  17. 34. clinical symptoms present on the same side of the body to the lesion site
  18. 36. is a sudden and momentary contraction of muscle groups
  19. 37. cerebral artery is responsible for supplying surfaces of the prefrontal, frontal, and parietal lobes.
  20. 38. Nerves in the PNS have 31 pairs in the
