1. Execrcise 20: Types of Tissues

2. Epithelial Tissue

6. Muscular Tissue

8. How is a synctium brought about?
Through the fusion of multiple uninucleate cells to
produce a single multinucleate cell

9. Connective Tissue

10. Hyaline Cartilage
 present in the nose,
larynx, and trachea
 skeletal cartilage in
the embryos of all
vertebrates
 skeletal cartilage of
adult sharks and
rays

11. Elastic cartilage
 external ears,
 eustachian tube,
 epiglottis

12. Fibrocartilage
 intervertebral
disks,
 pubic symphysis,
 disks of knee joint,
 and pads between
femur and tibia

14. Bone
 Bone prepared by the grinding method
 Removes the oscteocytes but preserves the
extracellular matrix

15. Vascular Tissue

18. Neutrophil
 2-5 or more thin
lobes, connected by
slender chromatic
threads
 phagocytic

19. Basophil
 nuclei stain very
faintly, often obscured
by cytoplasmic
granules; U or J-
shaped
 Inflammatory reaction

20. Eosinophil
 2 oval lobes linked by
thread-like
chromatin
 against helminthic
infections

21. Monocyte
 nuclei vary slightly,
indented ovals to
horse-shoe shaped
structure
 Becomes
macrophage,
phagocytic

22. Lymphocyte
 large, somewhat
spherical with some
indentations and only
slightly concentric
position
 Antibody production

24. Blood
 Erythrocytes
 Transport of necessary metabolites, wastes,
oxygen
 Leukocytes
 Immune system --> for defense

25. Nervous Tissue

29. Execrcise 21: Frog Organs

31. Chromatophores
 Pigment containing cells
 Provides coloration for camouflage, courtship,
defense

32. Cutaneous glands
 Also known as mucous glands
 Secretes mucous
 Keeps skin moist for respiration and protects
the frog from predators

33. Liver

35. Goblet Cells
 Secretes mucin which
reacts with water to
form mucus
 Mucus acts to
lubricate the internal
lining of the intestine
 Apocrine secretion

36. Mesothelium
 Simple squamous
epithelium
 Lines all visceral
organs as the visceral
epithelium
 Lines body cavities as
parietal epithelium

38. Stomach
1. 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 layer
2. Muscularis mucosa
 lies outer to the lamina propia
 has stratum circulare and stratum longitudinale
3. Tela submucosa
 contains large blood and lymph vessels
4. Tunica submuscularis
 thick and made up of circular layer of smooth muscles
5. Subserosa
 narrow layer of connective tissues containing few longitudinal muscle
strands
6. Tunica serosa

39. Intestine
Tunica mucosa

 lines cavity of lumen
 made up of simple columnar epithelial cells and goblet cells
Tunica submucosa

 muscular coat
 made up of two layers of muscles
 stratum circulare – thick inner circular layer
 stratum longitudinale – thin outer longitudinal layer
Tunica serosa

 outermost covering
 a thin layer of loose connective tissue covered with mesothelium

40. Gastric Glands
 Neck cells --> secrete mucus
 Parietal cells --> secrete gastric acid / Hcl
 Zymogenic cells --> secretes the zymogen,
pepsinogen

41. 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

43. Kidney
 Adrenal gland --> endocrine system
 Veins vs. arteries --> thickness of walls

45. 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
