Applied Anatomy and Physiology for Manual Therapists Applied Anatomy and Physiology for Manual Therapists Detailed Outline and Resources for Lesson Planning Every teacher’s lesson plan is different due to a number of variables including content, class length, personal teaching style, students’ needs, available resources, and materials. This ancillary has been created to provide you with a detailed outline of the contents of Applied Anatomy and Physiology for Manual Therapists by chapter. Additional resources available to you through LWW as well as suggestions for presentation, learning exercises, and group activities are listed to help you put together an engaging and effective lesson plan for your class. Chapter 12 — Immunity and Healing Learning Objectives: Upon completion of this chapter, the student will be able to: 1. Explain the function of the immune system and discuss its relationship with and importance to manual therapy practices. 2. Explain the difference between primary and secondary lymphoid tissues. 3. Name, locate, and describe the general function of the primary and secondary lymphoid tissues. 4. Explain the difference between nonspecific defenses and specific immune responses. 5. List the nonspecific immune defenses of the body and explain how each mechanism works. 6. Name and describe the roles of the primary lymphocytes involved in antibody-mediated and cell-mediated immune responses. 7. Discuss the difference between naturally and artificially acquired immunity and give examples of active and passive forms of each. 8. Discuss the immune system changes that commonly occur with aging. 9. Define the field of study known as psychoneuroimmunology and explain what implications this discipline may bring to the practice of manual therapy. Archer&Nelson-Detailed Outline & Resources for Lesson Planning-CH12-PA&LN-07.09.11 Page 1 of 5 Applied Anatomy and Physiology for Manual Therapists Detailed Outline Introduction to immunity and healing Define pathogens Immunity = protection or resistance to infection and disease Involves many body systems and processes Define healing (physically and holistically) Define psychoneuroimmunology (PNI) and foreshadow later information/discussion Obj Text pages PPt slides 1 310 1-2 2,3 3103-7 Lymphoid tissues and organs 313 Note that lymphoid is used instead of lymphatic (lymphoid for immune structures related to lymphocytes vs. lymphatic meaning related to lymph fluid return) Lymphoid (immune) tissue not physically connected but scattered throughout the body: o Primary lymphoid tissues where mature lymphocytes are produced include (Fig 12-2): Red bone marrow produces B cells Thymus produces T cells o Secondary lymphoid organs are sites of immune responses and include (Fig 12-1): Lymph nodes Filtering stations for foreign particles (macrophages eat) Pathogens recognized by lymphocytes set off response and node swells Spleen Left upper quadrant above stomach Similar function to nodes, but filters blood instead of lymph Also serves as blood bank MALTs include: Peyer patches in SI Tonsils (Fig 12-3) Appendix Archer&Nelson-Detailed Outline & Resources for Lesson Planning-CH12-PA&LN-07.09.11 S&RG Additional Resources and Sample Activities If your program includes energy and/or Eastern practices, this chapter provides many opportunities to make links between Western understandings of A&P and energy, spirit, life force, Qi etc. Ex 1,2 Refer students to the Pathology Alert: Tonsillitis and discuss as an example of a localized infection. Compare with appendicitis and/or hepatitis (other organ infections). Use S&RG Ch 12, Ex 2, as an in-class review exercise for primary versus secondary lymphoid tissues Page 2 of 5 Applied Anatomy and Physiology for Manual Therapists Non-specific (innate) immune defenses Universal responses not directed at any specific pathogen or foreign invader (Table 12-1) Define microbes These defenses include: o Physical barriers – skin, mucous membranes o Chemical barriers – sebum, sweat, tears, saliva, gastric juices, urine, vaginal secretions o Internal antimicrobial proteins – interferons, complement proteins, transferrins, antimicrobial peptides o Phagocytes – neutrophils, monocytes, and macrophages that do phagocytosis (Fig 12-4) (define chemotaxis) o Natural killer (NK) cells – destroy infected cells via cytolysis o Inflammation – chemical and cellular processes that enhance vasodilation, capillary permeability, clot formation, and phagocytosis (define pus) o Fever – elevated body temperature (discuss purpose) 4,5 Specific (adaptive) immune responses Acquired over time with exposure to pathogens that trigger responses of specific B and/or T lymphocytes Define antigen and antigen receptors There are 2 types of specific responses: o AMI (humoral) = involve B cells and antibodies (Fig 12-5) B cell recognizes specific antigen and is activated Activated B cell produces: Plasma cells – produce antibodies (immunoglobulins) Memory B cells – remember exposure Antibodies find other antigens and form complexes that neutralize or destroy invader 4,6 313315 8-14 Ex 1,3,5 Either refer students to Table 12-1 or ask students to create their own mind map or table that summarizes the innate immune defenses (S&RG) as an in-class review activity. Refer students to the Pathology Alert: Allergies. Define allergen and discuss signs and symptoms of anaphylaxis. Review cautions for manual therapists. Use the video animation to show the chemical and cellular responses involved in inflammation (Immune: acute inflammation). Ask students to compare inflammation in response to tissue injury versus infection. If hydrotherapy is taught in your program, ask students why one situation is treated with RICE, while the other is treated with moist heat. 316318 Archer&Nelson-Detailed Outline & Resources for Lesson Planning-CH12-PA&LN-07.09.11 15-17 Ex 1,4,5 Remind students of RBC antigens that create blood groups discussed in Ch 10. Refer students to and discuss the Pathology Alert: Autoimmune Diseases. Page 3 of 5 Applied Anatomy and Physiology for Manual Therapists o CMI = T cells (Fig 12-6) APC presents antigen to T cell that Use video animation to show and summarize the specific immune responses of the body (Immune: Immune response). recognizes it and is activated Activated T cell produces: Cytotoxic T cells – go out and kill the antigen Memory T cells – remember the exposure Helper T cells – release cytokines that promote T cell growth and plasma cell production of antibodies Suppressor T cells – shut down immune response when no longer needed Fig 12-7 summarizes immune responses Provide students a blank of Fig 12-7 (S&RG Ch 12, Ex 4) and ask them to complete it as an in-class review activity. Ask them to track their questions as they complete it and follow up the exercise with Q&A. Break students into pairs and have them write a story or analogy for immune processes (S&RG Ch 12, Ex 5). Acquisition of immunity Define immunological memory Explain difference between first and second exposure responses Naturally acquired immunity = without medical intervention o Active – exposed to pathogen in everyday life and develop own immunity o Passive – baby receiving antibodies during gestation or through breast-feeding Artificially acquired immunity = with medical intervention (immunizations) o Active – receive antigen (altered, dead, small dosage) and develop own immunity o Passive – receive antibody Table 12-2 summarizes immunity acquisition 7 318320 18-20 Aging and the immune system Identify common changes in the immune system related to aging: o B & T cells become less responsive o Thymus shrinks and number of T cells drops o Decrease in number and activity of NK cells increases incidence of cancer 8 320 21 Archer&Nelson-Detailed Outline & Resources for Lesson Planning-CH12-PA&LN-07.09.11 Ex 1,6 Use S&RG Ch 12, Ex 6, as an in-class review activity. Leave time for Q&A after completion. Discuss with students how these changes may affect their manual therapy treatments when working with the elderly. Page 4 of 5 Applied Anatomy and Physiology for Manual Therapists o o System less responsive to vaccinations Incidence of autoimmune dysfunction increases Psychoneuroimmunology Describe history of Cartesian division of mind-body-spirit Peptide network: o Define peptide, ligand o Ligands create responses in any cell with receptors, whether immune cells, neurons, or others o Ligand receptors densest in limbic system and other areas of brain associated with emotions Share your own thoughts on healing: o Biomedical versus holistic o Applications for manual therapists 1,9 320322 Archer&Nelson-Detailed Outline & Resources for Lesson Planning-CH12-PA&LN-07.09.11 22-24 Ex 1; GrA 1 Provide time for students to discuss the implication of PNI for their practice of manual therapy and share their thoughts on healing. Refer to S&RG Ch 12, GrA 1, for suggestions to spur discussion. Page 5 of 5
