Presentation Transcript

  1. Basic Sciences principles of physiology

  2. Surface Anatomy AKA - topographical anatomy

  3. Anatomical position

  4. The Planes of the Body • Anterior • Posterior • Midaxillary • Midline • Midclavicular line

  5. Directional Terms • Right and left • Superior and inferior • Lateral and medial • Proximal and distal • Superficial and deep • Anterior and posterior • Palmar and plantar • Unilateral and bilateral • Apices

  6. Review of degrees • 360 • 90 • 45

  7. patient positions SUPINE PRONE

  8. patient positions High Fowlers Semi Fowlers

  9. patient positions Left lateral or recovery position Shock position

  10. patient positions Trendelenburg Reverse Trendelenburg

  11. Fluid Compartments • Intravascular • determines blood pressure & perfusion • Interstitial • Intracellular

  12. osmosis & diffusion • osmosis = how fluid travels between compartments • diffusion = how gases are exchanged

  13. electrolytes • sodium (Na) - we are saline solutions • potassium (K) - for electrical function • Calcium (Ca) - muscle function • Bicarbonate (HCO3) - base buffer

  14. homeostasis • activity required to maintain balance between all body systems.

  15. atmosphere • oxygen - 21% • nitrogen - 78% • other - 1%

  16. Any Questions?
