10. The false statement about smooth muscle is:<br />A. Striated and cardiac muscle.<br /><br />11. Neurons in the retina are an example of:<br />B. Bipolar neurons.<br /><br />12. Nissl bodies are composed of:<br />A. sER and polysomes.<br /><br />13. The false statement about the functions of astrocytes is:<br />E. Producing myelin sheet in the central nervous system.<br /><br />14. Macrophages in the central nervous system are called:<br />D. Microglia.<br /><br />15. The features given above are of:<br />D. Foliate papillae.<br /><br />16. Dentine is made by:<br />D. Odontoblasts.<br /><br />17. Rigor mortis is the postmortem stiffening of muscles that occurs a few hours after death due to the depletion of ATP, leading to the inability of muscles to relax.<br /><br />18. The roles of the Golgi tendon organ include:<br />- Monitoring tension in muscles and tendons.<br />- Providing sensory feedback to the central nervous system about muscle tension.<br />- Helping to prevent muscle damage by signaling the need to relax muscles when tension becomes too great.
