Nervous System Lesson Plan Chapter 12 150 minutes Learning Objectives 1. Identify and define the combining forms and suffixes introduced in this chapter. 2. Correctly spell and pronounce medical terms and major anatomical structures relating to the nervous system. 3. Locate and describe the major organs of the nervous system and their functions. 4. Describe the components of a neuron. 5. Distinguish between the central nervous system, peripheral nervous system, and autonomic nervous system. 6. Identify and define nervous system anatomical terms. 7. Identify and define selected nervous system pathology terms. 8. Identify and define selected nervous system diagnostic procedures. 9. Identify and define selected nervous system therapeutic procedures. 10. Identify and define selected medications relating to the nervous system. 11. Define selected abbreviations associated with the nervous system. Minutes Concepts for Lecture 10 mins Identify and define the combining forms and suffixes introduced in this chapter.

Fremgen and Frucht, Lesson Plans for Medical Terminology, A Living Language, 5/e Teaching Notes Teaching Tips Word Watch: Point out the soundalike suffixes -phagia and -phasia. Help students remember the difference with the mnemonic “PHAGIA astr/o cephal/o cerebell/o cerebr/o clon/o dur/o encephal/o esthes/o gli/o medull/o mening/o meningi/o myel/o neur/o poli/o pont/o radicul/o thalam/o thec/o ton/o ventricul/o star head cerebellum cerebrum rapid contracting and relaxing dura mater brain sensation, feeling glue medulla oblongata meninges meninges spinal cord nerve gray matter pons nerve root thalamus sheath (meninges) tone brain ventricle Suffixes -paresis -phasia -plegia -taxia muscle -trophic weakness speech paralysis coordination pertaining to development involves your GUT; PHASIA involves SPEAKING.” Encourage/remind students to add new word parts to flash cards. Emphasize that it is more important to memorize word parts than individual terms, since many important terms can easily be defined by just breaking them down. Point out the relationship between the root cephal/o (head) and encephala/o (brain). Encephal/o can actually be further broken down into en- (within) and cephal/o (head), which is exactly where the brain is located. And, as an added bonus, both these word parts are already familiar to students from previous chapters. Did You Know? The combining form myel/o means “marrow” and is used for both the spinal cord and bone marrow. To the ancient Greek philosophers and physicians, the spinal cord appeared to be much like the marrow found in the medullary cavity of a long bone. Classroom Activities Medical Terminology Bee: Create PowerPoint flash cards of new combining forms, prefixes, and suffixes ©2013 by Pearson Education, Inc.

Fremgen and Frucht, Lesson Plans for Medical Terminology, A Living Language, 5/e els to illustrate the organization of the different parts of the nervous system Did You Know? Myelin is a lipid and a very white molecule. This is why myelinated neurons are called white matter. Because nerve tracts cross from one side of the body to the other side of the brain, damage to one side of the brain results in symptoms appearing on the opposite side of the body. Since nerve cells that control the movement of the right side of the body are located in the left side of the medulla oblongata, a stroke that paralyzed the right side of the body would actually have occurred in the left side of the brain.
