1 1. What are the two parts of the CNS? 2. What are the four functions of the CNS Anatomy & Physiology Central Nervous System Worksheet 3. What are the four functions of the meninges? (p430) 4. Starting with the most superficial, what are the three meninges? 5. Which of the following is NOT a function of the cerebrospinal fluid? nourish the CNS tissue protect the CNS from blows and trauma reduce brain weight by 97% and thus prevent the brain from crushing itself aids in the diagnosis of various diseases e) aid in the conduction of impulses in and around the brain 6. An inflammation of the meninges is called. 7. The layer of the meninges that clings closely to the brain and is composed of several tiny blood vessels is the mater. 8. The spinal cord ends around L-. 9. The gray matter of the spinal cord is in the shape of the letter. 10. A crossbar of gray matter called the connects the lateral gray masses. 11. The inferior end of the spinal cord terminates in a mass of branching nerves called the. 12. The posterior white column of the spinal cord mainly contains tracts of nerve fibers that are ascending descending transverse 13. The posterior or dorsal gray horns contain afferent / efferent tracts of sensory / motor neurons.

2 14. Descending tracts of the white mater of the spinal cord deliver afferent / efferent impulses that connect to receptors / effectors neurons. 15. How many pairs of spinal nerves branch off the spinal cord? 16. The five parts of a reflex arc are the, neuron, neuron, neuron, &. 17. The part of the reflex that is only located in the spinal cord is the neuron. 18. A muscle or gland that responds to a reflex is called the. 19. Reflexes that people are born with are called reflexes. 20. Reflexes that are learned over time (such as catching a ball) are called reflexes. 21. The three general parts of the brain are 22. The third & fourth ventricles are connected via the. 23. The first & second ventricles are also referred to as the ventricles. 24. The ventricles are filled with. 25. The ridges on the surface of the brain are called, while the shallow groves are called. 26. The four lobes of the cerebrum are 27. The fissure separates the left and right hemispheres, while the fissure separates the cerebral hemispheres from the cerebellum. 28. The sulcus separates the temporal lobe from the parietal & frontal lobes. 29. The primary motor cortex is located on the gyrus of the frontal lobe. 30. All motor areas are confined to the lobe. 31. The primary visual cortex is located on the lobe. 32. Judgment, reasoning, & problem solving skills are found on the lobe. 33. The primary auditory cortex is located on the lobe.

3 34. The senses of touch, temperature, & pain are located on the lobe. 35. The thin layer of gray matter that covers the cerebrum is called the. 36. The gyri & sulci function to increase the surface area of the cerebral cortex. Why is this important? 37. The connect the two hemispheres of the cerebrum. 38. The cerebellum is divided into two hemispheres by the. 39. The gray & white matter of the cerebellum form a plant-like shape called the of in English or the in Latin. 40. What is the function of the Cerebellum? 41. What are the four main parts of the Brainstem? 42. In what portion of the brain does crossing over occur? 43. What two parts of the Brainstem control respiration? 44. What two parts of the CNS contain white matter surrounding an H-shaped gray matter? 45. Which of the following is NOT controlled by the Medulla Oblongata? The cardiac center of heart rate. The respiratory center of breathing. The emetic center for vomiting. The vasomotor center of blood pressure. e) The endocrine center of hormonal control. 46. The mesencephalon is AKA the. 47. The interbrain is AKA the. 48. What sense is not relayed through the Thalamus? 49. What are Circadian Rhythms?

4 50. The Hypothalamus serves as a link between what two systems of the body? 51. The NS controls the body under ordinary conditions, while times of stress is controlled by the NS. 52. The hypothalamus is basically located the Thalamus. above below lateral inside 53. Death of brain tissue due to a blood clot or hemorrhage is called a. 54. What neurotransmitter is lacking in a person with Parkinson s disease? 55. A sever, 3-4 minute seizure is called a mal. 56. EEG stands for : 57. When taking a test (in here), what brain waves are probably most common? 58. What brain wave do we see in kids? 59. Color the parts of the brain (10 points) Frontal Lobe Red Parietal Lobe Blue Temporal Lobe Green Occipital Lobe - Orange e) Cerebellum Purple f) Pons Brown g) Medulla Oblongata Gray

5 60. Below is a diagram of a sagittal view of the human brain. Match the letters on the diagram with the following list of terms and insert the appropriate letters in the answer blanks. 1) Cerebellum 2) Cerebral Aquiduct 3) Cerebrum 4) Corpus Collosum 5) Fourth Ventricle 6) Hypothalamus 7) Medulla Oblongata 8) Optic Chiasm 9) Pineal body 10) Pituitary gland 11) Pons 12) Thalamus 13) Third Ventricle A M B C D L E J K F G H I
