  1. Human Anatomy Terminology ASA Bio 2014 Williams

  2. Anatomy & Physiology

  3. Standard anatomical position (SAP) • Standing straight • Palms forward • No bones crossed!

  4. Anatomical Planes • Coronal – separates into FRONT & BACK parts • Sagittal – separates into RIGHT & LEFT parts • Transverse – separates into TOP & BOTTOM parts

  5. Anatomical planes & Directional terms

  6. Anatomical planes & Directional terms

  7. Anatomical planes & Directional terms

  8. Directional Terms • SAGITTAL PLANE • Separates body into right & left parts • Midline: exact middle of body (sagittal plane) • Medial: towards the midline • Lateral:away from the midline

  9. Directional Terms • CORONAL PLANE • Separates body into front & back parts • Anterior: forward of coronal plane • Posterior: behind coronal plane

  10. Directional Terms • TRANSVERSE PLANE • Separates body into top & bottom parts • Superior: above transverse plane • Inferior: below transverse plane

  11. Major divisions of the body • Cranial – skull • Infracranial – the rest of the body • Axial – trunk & head (parts in midline) • Appendicular – appendages/ limbs • Includes pelvic and shoulder girdles

  12. Directions in appendicular skeleton

  13. Directional Terms • APPENDICULAR SKELETON • Appendages/ Limbs • Distal: away from body • Proximal: towards body

  14. Additional directional terms Palmar: Dorsal: Palm of hand Back of hand

  15. Additional directional terms Dorsal: Plantar: top of foot bottom (sole) of foot

  16. Terms of movement • Flexion Decreasing angle between bony elements at joint • Extension Increasing angle between bony elements at joint

  17. Terms of movement • ABduction Moving away from the midline • ADduction Moving towards the midline

  18. Terms of movement • Medial Rotation Rotating medially (in to the body) • Lateral Rotation Rotating laterally (away from the body

  19. Terms of movement • Pronation Placing palm posteriorly • Supination Placing palm anteriorly

  20. Terms of movement • Dorsiflexion Decrease angle between foot and leg • Plantarflexion Increase angle between foot and leg

  21. Terms of movement • Inversion Sole of foot towards midline • Eversion Sole of foot away from midline

  22. Terms of movement • Circumduction Combined movements of flexion/extension, adduction/abduction, etc

  23. Paired movements • Flexion/ Extension sagittal plane • ADduction/ ABductioncoronal plane • Medial/ Lateral rotation transverse plane
