  6. HIERARCHY CONT. • CELL (CYTOLOGY; CELL BIOLOGY) • NUCLEUS • CELL MEMBRANE (plasma membrane, phospholipid bilayer) • CYTOPLASM (cytosol) • MITOCHONDRIA (cellular respiration; conversion of glucose to carbon dioxide and water and ATP)

  7. HIERARCHY CONT. • CELL • LYSOSOME (digestive enzymes) • PEROXISOMES (detoxification, especially alcohol) • ENDOPLASMIC RETICULUM • SMOOTH ER (synthesis of lipids, detox, drug tolerance) • ROUGH ER (protein assembly) • GOLGI APPARATUS (post-translational modification)

  8. Hierarchy cont • CELL • NUCLEUS (in eukaryotes, protects genetic info) • FLAGELLA AND CILIA (cell movement; 9=2 array)

  9. HIERARCHY CONT • TISSUE (HISTOLOGY) • EPITHELIAL (epithelium and endothelium, glands) • CONNECTIVE (dense connective like bone, adipose, loose connective like blood vessels, and blood and lymph) • MUSCLE (cardiac, smooth, skeletal) • NERVOUS (nerves, spinal cord, brain)

  10. HIERARCHY CONT • ORGANS (see Table 2.2) • ORGAN SYSTEMS • RESPIRATORY • NERVOUS • DIFESTIVE • CIRCULATORY • ALL LEADS TO HUMA ORGANISM

  11. ANATOMY • BODY PLANES • VERTICAL (rt angle to horizon) • MIDSAGITTAL – vertical, rt and left halves • SAGITTAL – unequal left and right portions • CORONAL- divides into anterior and posterior

  12. ANATOMY • BODY DIRECTIONS • ANTERIOR/VENTRAL • POSTERIOR/DORSAL • SUPERIOR AND INFERIOR • CEPHALIC AND CAUDAL • PROXIMAL AND DISTAL • MEDIAL AND LATERAL

  13. BODY CAVITIES • DORSAL (cranial and spinal) • VENTRAL • Thoracic- ends at diaphragm • Abdominal • Pelvic- mainly reproduction and excretion • abdominopelvic

  14. Abdominal divisions • Right upper • Left upper • Right lower • Left lower

  15. ABDOMEN AND THORAX REGIONS • RT AND LEFT HYPOCHONDRIAC • EPIGASTRIC • RT AND LEFT LUMBAR • UMBILICAL • RT AND LEFT ILIAC • HYPOGASTRIC

  16. PERITONEUM

  17. PERITONEUM • Membrane • Parietal – outer • Visceral – inner • Mesentery • Retroperitoneal • Ascites – fluid in peritoneum

  18. CYTOLOGY • DNA • GENES • MUTATION (somatic vs gametic) • Genetic disorders • Huntington’s disease • Cystic fibrosis • Hemophilia • Down syndrome

  19. GENETIC DISORDER CONT • Sickle cell anemia • Tay sachs • Phenylketouria • Genetic vs congenital • Fetal alcohol syndrome • Cerebral palsy
