Title: Lecture 2 Terminology and Body Plan for the Human Body


1
Lecture 2Terminology and Body Plan for the Human
Body
2
Anatomical PositionThe Standard for Reference
  • Anatomical Position
  • Body erect, face forward, feet together, palms
    face forward
  • Other Body Positions
  • Supine lying face upward
  • Prone lying face downward

3
Body Planes
  • Sagittal / Midsagittal (Median)/ Parasagittal
  • Frontal (Coronal)
  • Transverse (Horizontal) / Cross
  • Oblique Other than at a right angle

4
Terminology and Body Plan
  • Directional Terms
  • Superior versus Inferior
  • Anterior/Ventral versus Posterior/Dorsal
  • Medial versus Lateral
  • Proximal versus Distal
  • Superficial versus Deep

Body Cavities

Serous Membranes
  • Cover the organs of trunk cavities line them
  • Parietal lines cavity walls
  • Visceral covers organs
  • Serous fluid secreted for lubrication by
    membranes
  • Named for their specific cavity organs
  • Pericardium refers to heart
  • Pleura refers to lungs and thoracic cavity
  • Peritoneum refers to abdominopelvic cavity

Points to Remember
  • Anatomical terms are very precise in anatomy so
    that one can accurately describe the body and its
    many parts.
  • The anatomical position is our universal
    reference for directional terms and body planes.
  • Body cavities contain and often separate organs.
  • Serous membranes cover the surfaces of organs and
    the wall of the trunk cavity.
