Study Notes

Organization of the Body

  • The body is organized in structural levels:
    • Cells: The basic unit of life
    • Tissues: Groups of similar cells working together
    • Organs: Structures composed of different tissues performing specific functions
    • Systems: Groups of organs working together to perform a comprehensive function
    • Organism: The complete living being, resulting from all the systems working together

Cells

  • Common components include:
    • Cell membrane: Regulates the passage of substances in and out of cells
    • Nucleus: Controls cell activities
    • Mitochondria: Generates energy for the cell (powerhouse)
    • Cytoplasm: The watery fluid surrounding the nucleus that contains organelles

Tissues

  • Tissues are formed from groupings of similar cells
  • Four main tissue types:
    • Muscle tissue: Enables movement
    • Connective tissue: Supports and connects other tissues
    • Nerve tissue: Transmits nerve impulses
    • Epithelial tissue: Covers and lines body surfaces

Organs

  • Organs are structures composed of different tissues, performing specialized functions
  • Examples include the brain, stomach, and heart

Systems

  • Systems are groups of organs working together to perform a comprehensive function
  • Each system has a specific purpose

Anatomic Position

  • Body is erect, facing forward
  • Palms face forward, arms at sides
  • Left and right are determined from the subject's perspective, not the observer's perspective

Directional Terms

  • Superior (cranial/cephalic): Toward the head
  • Inferior (caudal): Away from the head
  • Anterior (ventral): Toward the front of the body
  • Posterior (dorsal): Toward the back of the body
  • Medial: Toward the midline of the body
  • Lateral: Away from the midline of the body
  • Proximal: Closer to the point of attachment
  • Distal: Farther from the point of attachment
  • Supine: Lying face up
  • Prone: Lying face down

Body Planes

  • Transverse (horizontal) plane: Divides the body into top and bottom portions
  • Frontal (coronal) plane: Divides the body into front and back portions
  • Sagittal plane: Divides the body into left and right portions

Body Cavities and Divisions

  • Cranial cavity: Encloses the brain
  • Spinal cavity: Houses the spinal cord
  • Thoracic cavity: Contains the heart and lungs
  • Abdominopelvic cavity: Divided into abdominal and pelvic cavities, housing digestive organs and reproductive organs respectively

Regions of the Spinal Column

  • Cervical: The neck region
  • Thoracic: The chest region
  • Lumbar: The lower back region
  • Sacrum: The fused vertebrae of the pelvis
  • Coccyx: The tailbone

    • Answer: Hypo- (below), gastr- (stomach), -ic (pertaining to). Hypogastric means pertaining to below the stomach.

  • Question: Analyze this term: Myalgia

    • Answer: My- (muscle), -algia (pain). Myalgia means muscle pain.

  • Question: Analyze this term: Hypochondriac

    • Answer: Hypo- (below), chondr- (cartilage), -iac (pertaining to). Hypochondriac means pertaining to below the cartilage (rib cartilage).

  • Question: Analyze this term: Thoracic

    • Answer: Thorac- (chest), -ic (pertaining to). Thoracic means pertaining to the chest.
