2401 Review III - 1 2401 Exam 3 Review – True and False Statements (Be sure to correct the false statements) 1. A ganglion is a collection of neuron cell bodies in the CNS. 2. A graded potential can always be called an end-plate potential. 3. A graded potential is also called an impulse. 4. A horn is a region of white matter within the spinal cord. 5. A large motor unit contains more neurons than does a small motor unit. 6. A motor end plate is also called the synaptic cleft. 7. A person is least likely to bend his/her arms or legs while dreaming during REM sleep. 8. A person’s alpha brain waves are more common when he/she is taking an exam. 9. A sarcomere is larger than a myofibril but is smaller than a myofilament. 10. A single axon can stimulate only one skeletal muscle fiber. 11. A single neuron can innervate more than one skeletal muscle fiber. 12. A skeletal muscle fiber is usually stimulated by more than one axon 13. A spinal cord column contains bundles of axons. 14. According to the size principle, larger muscles can lift heavier loads than smaller muscles. 15. Ach-gated potassium channels are most closely associated with the generation of an end-plate potential on a skeletal myofiber. 16. After a skeletal myofiber repolarizes, Ca 2+ ions detach from troponin and calcium pumps move them back into the SR. 17. An axon that conducts impulses to produce precise movements of the eyeball is a class “A” fiber. 18. An axon that conducts impulses to skeletal myofibers uses the continuous method of conduction. 19. An end plate potential on a cardiac muscle fiber is always an EPSP. 20. An end plate potential on a skeletal muscle fiber is always an EPSP. 21. An end plate potential on a smooth muscle fiber is always an EPSP. 22. An EPSP results when chloride ions enter a presynaptic neuron. 23. An oxygen debt results whenever lactic acid is forming in a muscle fiber. 24. Another impulse cannot be generated on a muscle cell during the contraction period. 25. Applying a subthreshold stimulus to a myofiber causes the myofiber to experience incomplete tetanus. 26. Astrocytes secrete fluid into brain ventricles and circulate it with beating cilia. 27. ATP must bind to tropomyosin before a recovery stroke can occur in any myofiber. 28. Attaching a phosphate group to a myosin crossbridge initiates the powerstroke. 29. Axons within a nerve can regenerate through a tube of regenerated neurolemmocytes. 30. Beneath a mucous membrane, the lamina propria secretes the reticular lamina (this is an old question). 31. Beta waves are the most common brain wave during sleep. 32. Broca’s area is most closely associated with the interpretation of language. 33. Calcium ions must leave an axon terminal before the terminal will release neurotransmitter. 34.
