Bio 11 third_exam_post_labs

  1. 1. Execrcise 20: Types of Tissues
  2. 2. Epithelial Tissue
  3. 3. Muscular Tissue
  4. 4. How is a synctium brought about?Through the fusion of multiple uninucleate cells to produce a single multinucleate cell
  5. 5. Connective Tissue
  6. 6. Hyaline Cartilage present in the nose, larynx, and trachea skeletal cartilage in the embryos of all vertebrates skeletal cartilage of adult sharks and rays
  7. 7. Elastic cartilage external ears, eustachian tube, epiglottis
  8. 8. Fibrocartilage intervertebral disks, pubic symphysis, disks of knee joint, and pads between femur and tibia
  9. 9. Bone Bone prepared by the grinding method  Removes the oscteocytes but preserves the extracellular matrix
  10. 10. Vascular Tissue
  11. 11. Neutrophil  2-5 or more thin lobes, connected by slender chromatic threads  phagocytic
  12. 12. Basophil  nuclei stain very faintly, often obscured by cytoplasmic granules; U or J- shaped  Inflammatory reaction
  13. 13. Eosinophil  2 oval lobes linked by thread-like chromatin  against helminthic infections
  14. 14. Monocyte  nuclei vary slightly, indented ovals to horse-shoe shaped structure  Becomes macrophage, phagocytic
  15. 15. Lymphocyte  large, somewhat spherical with some indentations and only slightly concentric position  Antibody production
  16. 16. Blood Erythrocytes  Transport of necessary metabolites, wastes, oxygen Leukocytes  Immune system --> for defense
  17. 17. Nervous Tissue
  18. 18. Execrcise 21: Frog Organs
  19. 19. Chromatophores Pigment containing cells Provides coloration for camouflage, courtship, defense
  20. 20. Cutaneous glands Also known as mucous glands Secretes mucous Keeps skin moist for respiration and protects the frog from predators
  21. 21. Liver
  22. 22. Goblet Cells  Secretes mucin which reacts with water to form mucus  Mucus acts to lubricate the internal lining of the intestine  Apocrine secretion
  23. 23. Mesothelium Simple squamous epithelium Lines all visceral organs as the visceral epithelium Lines body cavities as parietal epithelium
  24. 24. Stomach1. Tunica mucosa  has inner layer of columnar cells and outer layer of loose connective tissue, the lamina propia  chief cells and parietal cells are found in this layer2. Muscularis mucosa  lies outer to the lamina propia  has stratum circulare and stratum longitudinale3. Tela submucosa  contains large blood and lymph vessels4. Tunica submuscularis  thick and made up of circular layer of smooth muscles5. Subserosa  narrow layer of connective tissues containing few longitudinal muscle strands6. Tunica serosa
  25. 25. IntestineTunica mucosa  lines cavity of lumen  made up of simple columnar epithelial cells and goblet cellsTunica submucosa  muscular coat  made up of two layers of muscles  stratum circulare – thick inner circular layer  stratum longitudinale – thin outer longitudinal layerTunica serosa  outermost covering  a thin layer of loose connective tissue covered with mesothelium
  26. 26. Gastric Glands Neck cells --> secrete mucus Parietal cells --> secrete gastric acid / Hcl Zymogenic cells --> secretes the zymogen, pepsinogen
  27. 27. Muscle layers Muscularis mucosa --> moves the rugae, expels contents of gastric glands and allows for more exposure of epithelia with the chyme Tunical muscularis --> responsible for gut movement which churns the food
  28. 28. Kidney Adrenal gland --> endocrine system Veins vs. arteries --> thickness of walls
  29. 29. Spinal Cord Central Canal --> cerebrospinal fluid (CSF) Motor Neurons --> soma are spindle shaped, carries motor impulses which causes muscular contraction Multipolar neuron --> includes all motor neurons and internuerons, long axon, many dendrites
