Hearing is controlled in the A) frontal lobe. B) temporal lobe. C) occipital lobe. 48. Describe the nerve impulse as it travels along a nerve fiber and across a synapse. nerve impulse is a wave of depolarization and repolarization, during which sodium ions first move into a neuron and then potassium ions move out of a neuron. This is called an action potential. When the action potential reaches the end of the axon, neurotransmitter substances are released into the synapse between adjacent neurons. These chemicals diffuse across the synapse and initiate an action potential in the next neuron. 49. Describe how the spinal cord acts as a reflex center and a relay center. Ans: The gray matter of the spinal cord contains the sensory neurons, interneurons, and motor neurons involved in spinal reflexes. The white matter of the spinal cord contains nerve tracts composed of nerve fibers carrying impulses toward or away from the brain. 50. List the parts of the unconscious brain and state the function of each part. iencephalon - maintains homeostasis (Hypothalamus) and serves as a relay station for sensory impulses traveling toward the cerebrum (Thalamus) Cerebellum - controls balance and complex movements Medulla oblongata - contains vital centers and reflex centers Pons - contains axons traveling between the cerebellum and the rest of the CNS, and also contains vital centers and reflex centers Midbrain - contains tracts traveling between the cerebrum, cerebellum, and spinal cord, and reflex centers 51. If a person had an injury to the occipital lobe of the cerebrum, what functional losses would you expect them to have? Ans: vision and visual recognition of objects Page 67

9 52. When someone is frightened, they seem to have more strength to run or fight than normal. What is the reason for this? Ans: The sympathetic nervous system releases the neurotransmitter norepinephrine which accelerates the heartbeat and increases respiration. 53. List the causes of Parkinson, Huntington, and Alzheimer disease. Ans: Parkinson - deficiency of the neurotransmitter dopamine Huntington - malfunction of the neurotransmitter GABA Alzheimer - loss of neurons that use ACh as a neurotransmitter 54. Compare the left and right brain with regard to their abilities. Ans: The left brain contains centers for speech and is responsible for language ability. The right brain is better at dealing with spacial relationships, musical and artistic ability, and expression of emotions. 55. Organize the following divisions of the nervous system in outline form: autonomic ns, central ns, parasympathetic ns, peripheral ns, somatic ns, sympathetic ns. Ans: I. Central ns II. Peripheral ns A. Somatic ns B. Autonomic ns 1. Sympathetic ns 2. Parasympathetic ns 56. List the following reflex arc components in the order that they would function in producing reflex activity: effector organ, interneuron, motor neuron, receptor, sensory neuron. Ans: Receptor, sensory neuron, interneuron, motor neuron, effector organ. 57. Compare the cerebrum and spinal cord with regard to the location of gray and white matter. Ans: Whereas gray matter is found in the center, or core, of the spinal cord, white matter is found near the surface. In the cerebrum, the gray matter is near the surface and the white matter is deeper. 58. Differentiate between gyri, sulci, and fissures. gyrus is a convolution (bump) on the surface of the cerebrum. A sulcus is a shallow groove between gyri. A fissure is a deep groove. 59. List and describe the three types of functional areas in the cerebrum. Ans: 1. Sensory areas receive sensory impulses and produce sensations. 2. Motor areas initiate nerve impulses that control muscle fibers. 3. Association areas are believed to contain areas for intelligence, artistic and creative ability, and learning. Page 68

10 60. The summing up of excitatory and inhibitory signals received by a neuron is called A) summation. B) potentiation. C) integration. D) transmission. 61. Which is the most superficial menix? A) arachnoid B) dura mater C) pia mater 62. The primary somatosensory area A) receives impulses from the skin and skeletal muscles. B) is posterior to the central sulcus. C) is located in the parietal lobe. D) All of these choices are correct. 63. Which is not a component of the brain stem? A) cerebellum B) medulla oblongata C) midbrain D) pons Page 69
