Melanie Evangelista Physiology HWK THANKSGIVING PROJECT 12. What does cerebral lateralization refer to? What functions tend to be centered in each hemisphere? Asymmetrical distribution of function between the two lobes of the cerebrum. Left brain- language add vertebral functions; right brain-spatial skills. 13. Match each of the following areas with its function. a. 5 b. 7 c. 9 d. 3 e. 1 f. 2 g. 6 h. 8 i. 4 14. Name the 12 cranial nerves in the numerical order and their major functions. 15. Name and define the two major phases of sleep. How are they different from each other? REM (rapid eye movement) sleep-when most dreaming takes place. Rapid, low- amplitude of homeostatic function. Slow-wave (deep) sleep- high amplitude, low frequency EEG waves and unconscious body movements. 16. List several homeostatic reflexes and behaviors influenced by output from hypothalamus. What is the source of emotional input into this area? Homeostasis of body temperature and osmolarity, reproduction functions, hunger and satiety, and cardiovascular function .Emotional input for the limbic system. 17. The amygdala region of the limbic system is believed to be the center for basic instincts (such as fear) and learned emotional states. 18. What are the broad categories for learning? Define habitation and sensitization. What anatomical structure of the cerebrum is important in both learning and memory. Associative and non-associative. Habituation- a person responds less and less to a repeated stimulus, sensitization-an enhanced response to a dangerous or unpleasant stimulus. Hippocampus is involved in learning and memory. 19. What two centers of the cortex are involved in integrating spoken language? Broaca’s read and Wernick’s area.

Melanie Evangelista Physiology HWK THANKSGIVING PROJECT Level Two 20. Mapping exercise: map the following terms describing CNS anatomy .You may draw pictures or add terms if you wish. 21. Trace the pathway that the cerebrospinal fluid follows through the nervous system. Secreted into the ventricles and fled into the subarachnoid space around the brain and spinal cord before being reabsorbed by the cerebral arachnoid membrane. 22. What are the three brain systems that regulate motor output by the CNS? sensory system, behavioral state system, and cognitive system 23. Explain the role of Wernick’s and Broca’s area in language. Werncik’s are- understanding language, Broca’s area- produce language. 24. Compare and contrast the following concepts: a. Diffuse modulatory- attention, motivation, wakefulness, memory, motor control, mood, and metabolism. Reticular formation- arousal and sleep, muscle tone breathing, blood pressure, and pain. Reticular activating system-helps maintain consciousness. Limbic system-links higher sgonitive functions with more primitive emotions such as fear.

What students are saying

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
