  2. Multiple choice 20 pts on scantron sheet

  3. Neurons • Be able to name the parts of a neuron and the functions of those parts

  4. Brain • Parts of the Brain • Functions of those parts Parts of the Brain

  5. Divisions of Nervous System • Central Nervous System • What it consists of • Functions of the parts • Peripheral Nervous System • What it consists of • Two Divisions • Somatic • Autonomic • Sympathetic Nervous System • Parasympathetic Nervous System

  6. Senses • Eye • Parts of the Eye • Functions of those parts • Ear • Parts of the Ear • Functions of those parts • Smell and Taste

  7. Nervous System Disorders • What they are and what causes them—to the extent that we looked at them in class.

  8. Short Answer 25 pts—lots of choice! (I will not be giving you all of the questions)

  9. Entire rewrite of test to include lots of choice for students. That means you have to circle the # of the question you are answering!

  10. Questions include: • During a lumbar puncture (spinal tap), a hollow needle is inserted into the subarachnoid space between L3 and L4 (the 3rd and 4th lumbar vertebrae). Why is there no danger of injuring the spinal cord with the needle during this procedure? • Why does exposure to toxins have more devastating effects during early pregnancy than in late pregnancy? Bookwork

  11. Questions include: • Describe four basic components of the reflex arc. • Explain how nerve impulses are initiated and transmitted and why one-way conduction at synapses always happens. Labs and bookwork

  12. Questions include: • Why is Babinski’s sign NORMAL in a newborn but indicative of nerve damage in anyone else? • Explain the difference between sensorineural deafness and conductive deafness. Labs

  13. Questions include: • An elderly gentleman has just suffered a stroke. He is able to understand verbal and written language, but when he tries to respond, his words are garbled. What cortical region has been damaged by the stroke? • A young man has just received serious burns, resulting from standing with his back too close to a bonfire. He is muttering that he never felt the pain. Otherwise, he would have smothered the flames by rolling on the ground. What part of his CNS might be malfunctional? WS

  14. Questions include: • A group of nine toddlers attending the same day care center developed red, inflamed eyes and eyelids. The day care sent home a note indicating that they have pink eye, or conjunctivitis. What does the conjunctiva of the eye do? • The elasticity of your lens decreases dramatically with age, resulting in difficulty focusing for near vision. What is this condition called? What test did we use in the lab to measure the elasticity of your lens? Labs

  15. Short Answers you MUST answer… There are three questions all of you will respond to.

  16. Mandatory Questions • Describe the steps involved in the generation of an action potential. Make sure to explain the operation/significance of the sodium/potassium pumps. • Myelination of peripheral neurons occurs rapidly throughout the first year of life. How can this process explain the increased abilities of infants during their first year? • As evidenced with the case studies we saw in class, differentiate between early and late Alzheimer’s patients in terms of memory ability, personality and affect.
