    Ch. 01 Intro to A & P Ch. 01 Intro to A & P Presentation Transcript

    • Chapter 1 Introduction to Human Anatomy and Physiology
    • Anatomy and Physiology Anatomy – study of structure/ location Physiology – study of function Structure is always related to function
    • Levels of Organization
    • Levels of Organization Organelle – mitochondrion, nucleus Cell – bone building cell (osteoblast) Tissue – bone (connective tissue) Organ – thigh bone (femur) Organ System – skeletal system Organism - human
    • Homeostasis Body’s maintenance of a stable internal environment
      • Homeostatic Mechanisms – monitor aspects of the internal environment and corrects any changes
        • Receptors - provide information
        • Control center - tells what a particular value should be
        • Effectors - causes responses to change internal environment
    • Organ Systems
    • Organ Systems
    • Organ Systems
    • Anatomical Terminology Anatomical Position – body standing erect, facing forward, upper limbs at the sides, palms facing forward
      • Terms of Relative Position
        • Superior versus Inferior
        • Anterior versus Posterior
        • Medial versus Lateral
        • Ipsilateral versus Contralateral
        • Proximal versus Distal
        • Superficial versus Deep
    • Body Sections
    • Body Cavities
    • Body Cavities Right and left are always reversed in anatomical drawings! Middle of sternum (heart, trachea, esophagus)
    • Serous Membranes
      • Thoracic Membranes
        • Visceral pleura
        • Parietal pleura
        • Visceral pericardium
        • Parietal pericardium
      Visceral layer – covers (touches) an organ Parietal layer – lines a cavity or body wall
      • Abdominopelvic Membranes
        • Visceral peritoneum
        • Parietal peritoneum
    • Serous Membranes
    • Serous Membranes
    • Body Regions These are the words we play Taber says with 
