Understanding Human Anatomy: Structure, Function, and Body Positioning

This comprehensive overview of human anatomy introduces the foundational concepts of anatomy and physiology, detailing how the body is structured and how its parts function. It covers gross and microscopic anatomy, relative position terminology (superior, inferior, anterior, posterior, etc.), and the importance of body planes. The description includes practical exercises such as drawing a stick figure in anatomical position and identifying key anatomical areas. Lastly, it explains body cavities and membranes relevant to thoracic and abdominopelvic regions, enhancing your understanding of human biology.

Presentation Transcript

  1. A Road Map thru the Body The vocabulary of Human Anatomy

  2. Anatomy – study of the structure and shape of the body and its parts • Physiology – study of how the body and its parts work or function • Gross Anatomy • Large structures • Easily observable • Microscopic Anatomy • Very small structures • Can only be viewed with a microscope

  3. Draw a stick-like figure, with a head, trunk, arms, and legs in anatomical position standing erect, facing forward, upper limbs at sides, palms facing forward. As the terms are discussed, designate the area or draw arrows on the paper to designate direction.

  4. Terms of Relative Position • Superior versusInferior • Anterior versus Posterior • Medial versusLateral • Proximal versusDistal • Superficial versusDeep

  5. Body Planes

  6. Identify the following areas on your stick figure: Area distalto the knee. Area proximalto the elbow. Lateralto the thumb. Area that is superiorto the lungs. Area that is inferiorto the heart. A structure that is anterior to the brain. Draw a line showing a transverse plane. 6 4 2 3 5 1

  7. Body Cavities

  8. Membranes Visceral layer – covers an organ Parietal layer – lines a cavity or bodywall • Thoracic Membranes • Visceral pleura • Parietal pleura • Visceral pericardium • Parietal pericardium • Abdominopelvic Membranes • Parietal peritoneum • Visceral peritoneum

  9. Abdominopelvic Quadrants

  10. Abdominopelvic Regions
