    Study Notes

    Studying Anatomy

    • Anatomy is the study of the structure of living organisms
    • The word "anatomy" is derived from the Greek word "anatemno" which means "to cut open; to dissect"
    • Many anatomical terms are derived from Greek and Latin
    • Andreas Vesalius, an anatomist and physician, published a book in 1543 called "De humani corporis fabrica libri septem" (On the Structure of the Human Body in Seven Books)

    Branches and Different Approaches To Studying Anatomy

    • Macroscopic or gross anatomy is the study of structures visible to the naked eye
    • Microscopic anatomy or histology is the study of structures that can only be seen with a microscope
    • Developmental anatomy or embryology is the study of the changes in structure that occur throughout the lifespan
    • Comparative anatomy is the study of the structures of different species

    Approaches to human gross anatomy:

    • Systemic anatomy is the study of the body's organ systems
    • Regional anatomy (topographical anatomy) considers the organization of the human body as major parts or segments.
    • Clinical anatomy focuses on anatomical structures involved in the diagnosis and treatment of diseases

    Levels of Structural Organization of the Human Body

    • The human body has six distinct levels of increasing complexity, from the smallest building blocks to a whole living organism:
      • Chemicals (atoms and molecules) level
      • Cells
      • Tissues
      • Organs
      • Organ systems (body systems)
      • Whole organism (human body)

    Systemic Anatomy

    • The integumentary system - the skin and its appendages
    • The skeletal system - consists of bones, cartilage, and joints
    • The muscular system - consists of skeletal muscles
    • The nervous system - consists of the brain, spinal cord, and nerves
    • The cardiovascular system - consists of the heart and blood vessels
    • The lymphatic system - a network of lymphatic vessels
    • The alimentary or digestive system - consists of the digestive tract from the mouth to the anus, with all its associated organs and glands
    • The respiratory system - consists of the air passages and lungs that supply oxygen to the blood
    • The urinary system - consists of the kidneys, ureters, urinary bladder, and urethra
    • The endocrine system - consists of specialized structures that secrete hormones
    • The genital (reproductive) system - consists of the gonads (ovaries and testes), the ducts, and the genitalia

    Anatomical Position

    • The anatomical position refers to the body position as if the person were standing upright with the following:
      • Head and toes directed forward
      • Arms on the sides with the palms facing forward
      • Lower limbs close together with the feet parallel
    • This position is adopted globally for anatomical and medical descriptions

    Planes and Sections

    • Sagittal plane: Vertical plane that divides the body into right and left parts
      • Midsagittal plane: Divides the body into equal halves
      • Parasagittal planes: Sagittal planes that are not midsagittal
    • Frontal (coronal) plane: Vertical plane that divides the body into anterior and posterior parts
    • Transverse (horizontal) plane: Divides the body into superior and inferior parts

    Directional Terms

    • Directional terms are used to describe the location and orientation of body structures in relation to each other.
    • Terms are paired with opposites:
      • Superior/inferior: Above/below
      • Anterior (ventral)/posterior (dorsal): Front/back
      • Medial/lateral: Towards the midline/away from the midline
      • Proximal/distal: Closer to the point of attachment/further from the point of attachment

    Terms of Movement

    • Flexion/extension: Bending/straightening
    • Abduction/adduction: Movement away from/towards the midline
    • Supination/pronation: Palm up/palm down
    • Rotation: Turning
    • Circumduction: Circular movement
    • Opposition: Touching the thumb to the other fingers
    • Eversion/inversion: Turning the sole of the foot outwards/inwards
    • Plantar flexion/dorsiflexion: Pointing the toes down/up
    • Elevation/depression: Raising/lowering
    • Protraction/retraction: Moving forward/backward

    Body Regions

    • Anterior View:
      • Abdominal, antebrachial, antecubital, axillary, brachial, buccal, carpal, cephalic, cervical, cranial, crural, digit, dorsum, facial, femoral, frontal, hallux, inguinal, mammary, manus, mental, nasal, ocular, oral, palmar, patellar, pelvic, pes, pollex, sternal, tarsal thoracic, umbilical
    • Posterior View:
      • Acromial, antebrachial, axillary, brachial, calcaneal, carpal, cephalic, cervical, cranial, digit, femoral, gluteal, lumbar, manus, occipital, olecranon, plantar, popliteal, sacral, sural, tarsal, vertebral

    Body Cavities and Their Subdivisions

    • The body contains several cavities that protect and support internal organs
    • Dorsal body cavity:
      • Cranial cavity: Contains the brain
      • Vertebral cavity: Contains the spinal cord
    • Ventral body cavity:
      • Thoracic cavity:
        • Two lateral pleural cavities (each containing a lung)
        • Mediastinum (contains the heart surrounded by the pericardial cavity)
      • Abdominopelvic cavity:
        • Abdominal cavity: Contains the stomach, intestines, liver, spleen, pancreas, and kidneys
        • Pelvic cavity: Contains the urinary bladder, reproductive organs, and the rectum

    Body Cavities and Serous Membranes

    • Serous membranes line body cavities and cover organs in those cavities so they can move easily against each other.
    • They consist of:
      • Parietal layer: Lines the cavity
      • Visceral layer: Covers the organ
      • Serous fluid: Slippery fluid between the two layers
    • Pericardium: Contains the heart
    • Pleura: Contains the lungs
    • Peritoneum: Lines the abdominal cavity
