  1. The Language of Anatomy

  2. What do scientists use to describe position of certain anatomical structures? • Visible Landmarks on the surface of the body can be specific in referring to different regions of the body.

  3. Anterior Body Landmarks • Anterior Body Landmarks describe frontal body regions of the body • Abdominal- anterior body trunk below the ribs • Acromial- point of the shoulder • Antecubital- frontal part of elbow • Axillary- armpit • Brachial- arm

  4. Posterior Body Landmarks • Posterior Body Landmarks describe the back regions of the body. • Calcaneal- heel of foot • Cephalic- head • Deltoid- curve of shoulder • Femoral- thigh • Gluteal- buttock

  5. What do directional terms mean? • Directional terms used by medical personnel and anatomists allow them to explain exactly where one body structure is in relation to another. • Superior- toward the head end or upper part of a structure of the body • Inferior- Away from the head end or toward the lower part of a structure or the body. Below.

  6. Body Planes and Sections • When preparing to look at the internal structures of the body, one must make a cut or section through the body or organ along an imaginary line. • Sagittal section • Frontal (coronal) section • Transverse section

  7. Sagittal Plane • Sagittal section is a cut made along the lengthwise or longitudinal plane of the body. • Midsagittal or median sections describes cuts directly down the middle of the body or organ.

  8. Frontal Plane • Frontal Section is a cut made along a lengthwise plane that divides the body or organ into anterior and posterior parts. • Aka coronal section

  9. Transverse Plane • Transverse section is a cut made along a horizontal plane, dividing the body or organ into superior and inferior parts • Aka Cross section

  10. Body Cavities • There are two main internal body cavities that provide degrees of protection to the organs within them. • Dorsal body cavity • Ventral Body Cavity

  11. Dorsal Body Cavity • Two subdivision • Cranial Cavity • Space inside the bony skull • Protects the brain • Spinal Cavity • Extends from the cranial cavity to the end of the vertebral column. • Protects the spinal chord

  12. Ventral Body Cavity • Three subdivisions • Thoracic cavity • Abdominal cavity • Pelvic cavity

  13. Abdominopelvic cavity
