  1. Planes
    are imaginary flat surfaces passing through the body
  2. Sagittal plane
    divides the body into right and left halves
  3. Frontal (coronal) plane
    divides the body into front & back portions
  4. Transverse (horizontal) plane
    divides the body into upper & lower portions; alsocalled a cross section.
  5. Axial Region
    • Head = cephalic
    • cranium = houses the brain
    • facial = face
    • Neck = cervical
    • thorax = above diaphragm
    • Abdomen = below diaphragm
    • Back = lumbar
  6. Appendicular region
    • Upper limb =arm
    • brachium =arm
    • antebrachium = forearm
    • carpus = wrist
    • manus = hand
    • digits = fingers
    • Lower limb =leg
    • inguinal =groin
    • femoral = thigh
    • crus = leg
    • tarsus = ankle
    • pedal = foot
    • digits = toes
  7. Major body cavities
    spaces filled with visceralorgans and lined with membranes
  8. Dorsal cavity
    • Cranial cavity = houses the brain; lined with meninge
    • Vertebral canal = houses the spinal cord; lined with meninge
  9. Ventral cavity
    • Thoracic cavity = houses the heart and lungs
    • Mediastinum = space above the heart
    • Pericardial cavity = contains the heart; membrane is pericardium
    • Pleural cavity = contains the 2 lungs; membrane is pleura
    • Abdominopelvic cavity =houses digestive, reproductive, and urinary organs and lined with the
    • peritoneum membrane
    • abdominal cavity = houses the stomach, pancreas, liver, gallbladder,spleen, intestines
    • pelvic cavity = houses the urinary bladder, female uterus and ovaries,rectum
  10. Abdominopelvic Quadrants
    • right upper quadrant, leftupper quadrant,
    • right lower quadrant, left lower quadrant
  11. Abdominopelvic Regions
    • r. hypochondriac, epigastric, l. hypochondriac,
    • r. lumbar, umbilical, l. lumbar,
    • r. inguinal, hypogastric, l. inguinal.
  12. Homeostasis
    the process of maintaining asteady state; the physiological mechanism that resets body functions tomaintain a stable, steady state
  13. Negative feedack
    • changes function to reverse its direction
    • Most common mechanism

    ex. sweating (vasodilation) or shivering (vasoconstriction)
  14. Positive feedback
    Pushes function in same direction

    ex. pregnancy
