  1. Overview of Anatomy A. Azami, Ph.D.

  2. Overview of Anatomy • Anatomy – the study of the structure of body parts and their relationships to one another • Gross or macroscopic • Microscopic • Developmental

  3. Gross Anatomy • Regional – all structures in one part of the body (such as the abdomen or leg) • Systemic – gross anatomy of the body studied by system • Surface – study of internal structures as they relate to the overlying skin

  4. MicroscopicAnatomy • Cytology – study of the cell • Histology – study of tissues

  5. Developmental Anatomy • Embryology – study of developmental changes of the body before birth

  6. Anatomical terminology • This generally relates to: • Names of the organ systems or regions • Names of body organs or their parts • Anatomical planes • Anatomical locations

  7. Anatomical planes

  8. Anatomical Planes • Saggital – divides the body into right and left parts • Coronal or frontal– divides the body into anterior and posterior parts • Horizontal or transverse (cross section) – divides the body into superior and inferiorparts

  9. Anatomical planes - 1 • Median or mid-saggitalplane • Passing from front to back in the long axis of the body IN the midline.

  10. Anatomical planes - 2 • Saggital:Saggital – divides the body into right and left parts

  11. Saggital plane

  12. Anatomical planes - 3 • Coronal or frontal:divides the body into anterior and posterior parts

  13. Coronal Plane

  14. Anatomical planes - 4 • Horizontal or transverse (cross section) :divides the body into superior and inferior parts

  15. Horizontal Plane

  16. Anatomical positions - 1 • 1. Cranial toward the head • 2. Caudal - toward the feet • 3. Medial - toward the middle • 4. Lateral - toward/from the side • 5. Proximal - toward the attachment of a limb • 6. Distal - toward the finger/toes • 7. Superior - above • 8. Inferior - below

  17. Anatomical positions - 2

  18. Anatomical movementsFlexion/Extension

  19. Regional Terms • Axial – head, neck, and trunk • Appendicular – appendages or limbs • Specific regional terminology

  20. Regional Terms

  21. Body Cavities • Dorsal cavity protects the nervous system, and is divided into two subdivisions • Cranial cavity is within the skull and encases the brain • Vertebral cavity runs within the vertebral column and encases the spinal cord • Ventral cavity houses the internal organs (viscera), and is divided into two subdivisions: thoracic and abdominopelvic
