1 Histology Exam Oct. 14, 2009 (Cartilage, bone, nervous tissue, muscle, GI tract) I. Matching. This section is mainly about muscle and nervous tissues. Match Column A with the correct answer from Column B. Answers in B may be used once, more than once, or not at all. Think and just do not take something from A and match it with the first thing you know is the correct answer in Column B. For example, if actin-myosin is in Column A and you match it with skeletal muscle from Column B that is not the correct answer because there is a better answer, namely, ‘cardiac, smooth, skeletal’ as actin- myosin is found in all three types of muscle (and in many more cells). Column A Column B 1. Bipolar neurons ___ A. smooth muscle 2. Troponin ___ B. macrophage 3. Muscle cells that branch ___ C. cardiac and smooth muscle 4. Centrally placed nucleus (muscle)___ D. skeletal muscle 5. Thoracic 1 to Lumbar 2 ___ E. cardiac, smooth, skeletal muscle 6. Microglia ___ F. cardiac 7. Myosin (in muscle) ___ G. cardiac and skeletal muscle 8. Dense bodies (muscle) ___ H. myelin for CNS 9. Striations in muscle ___ I. Sympathetic nervous system 10. Oligodendrocytes ___ J. special senses (sight, smell, and hearing) 11. Pseudounipolar neurons ___ K. smooth and skeletal muscle 12. Calmodulin ___ L. node of Ranvier 13. Nissl bodies ___ M. dorsal root ganglion 14. Gap junctions (muscle) ___ N. RER 15. Phosphorylation needed for contraction ___ II. Multiple Choice. All are EXCEPT questions, so be careful. Circle correct answer. THINK!
