1. Animal tissues

2. Histology: is the science that study animal tissues

3. Types of animal tissues: 1.Epithelial tissues. 2.Connective tissues 3.Muscular tissues 4.Nervous tissues

4. Epithelial tissues: Characteristics: 1.Lining surfaces. 2.Closely aggregated cells. 3.Very little amounts of intercellular substances. 4.Basement membrane below epithelial tissue

5. Shapes of epithelial tissues 1. irregular: squamous 2. cube-shaped: cuboidal 3. column-shaped: columnar

6. Number of layers 1.simple. 2.Stratified 3.Pseudostratified.

7. Cilia on epithelial tissue 1.Ciliated 2.Non-ciliated

8. Simple squamous epithelium

9. Simple cuboidal epithelium Kidney tubules

10. Simple columnar epithelium Villi of small intestine

11. Pseudostratified columnar ciliated ep.

12. Connective tissues 1.Connect between two parts of the body 2.High amounts of inter cellular substances 3.Fibers in matrix

13. Connective tissues 1.Loose connective tissues a.Connect between skin and underlining tissues. b.Visceral 1.Dens connective tissues Dens fibers

14. Loose connective tissue Areolar connective tissue

16. Adipose tissue

17. Dens connective tissue 1.Tendon: connect between muscles and bone 2.Ligament: connect between bones

18. tendon

19. Cartilage Chondrocyte ( cartilage cell) Types: 1.Hyaline cartilage. 2.Elastic cartilage 3.Fibro cartilage

20. Hyaline cartilage

21. Elastic cartilage

22. Bones 1.Solid connective tissue. 2.Solid matrix (ossien) Types: - Spongy bone - Combact bone

23. Spongy bone and combact bone 1.Spongy bone: bar-like extensions called trabaculae 2.Combact bone: haversian systems

24. Combact bone (haversian system)

25. Blood Components of blood: 1.White blood cells (leukocytes). 2.Red blood cells (erythrocytes). 3.Platelets. 4.plasma

26. Leukocytes

27. Muscular tissue

28. Skeletal muscle 1.Responsible for voluntary movement 2.Striated 3.Locate beside bones

29. Cardiac muscles 1.Responsible for involuntary movement. 2.Striated 3.Located in heart

30. Smooth muscles 1.Responsible for involuntary movement. 2.Non striated. 3.Located in digestive system.

31. Nervous tissue Nerve cell ( neuron)

32. Spinal cord
