1. TISSUE
The Living Fabric

2. Four Types of Tissue Epithelial (protection) Connective (support)
Muscle (movement)
Nervous (control)

3. Epithelial Tissue
Covering & Lining Epithelium
Glandular Epithelium

4. Classified by:
Shape
Number of Layers

5. Squamous Flattened and Scalelike

6. Cuboidal As tall as they are wide

7. Culumnar Tall, Column-Shaped

8. Arrangement
Simple
Stratified

10. Simple Squamous

11. Simple Columnar

12. Stratified Squamous

13. Pseudostratified Squamous

14. Functions of Epithelium
Protection
Absorption
Secretion
Sensory Functions

15. Features of Epithelium
Cell Junctions are Tight
Basement Membrane
Avascular (no vessels)
Highly Regenerative

16. Covering and Lining Epithelium

17. Location Endothelium: Simple, Reduces Friction (Vessels)
Mucous Membranes: Line body cavities that are open to the exterior. (Mouth, Nose)

18. Location
Cutaneous Membrane: Skin, Keratinized stratified squamous, dry membrane
Serous Membrane: Moist, Closed ventral body cavities, Reduce friction

19. Glandular Epithelium Specialized for Secretion
One or more epithelial cells
Exocrine: Ducts (Saliva glands, Pancreas)
Endocrine: Ductless, Directly into Extracellular Space (Hormones)

20. Connective Tissue

21. General Properties
Most abundant and varied of all tissues
Primary function: bind the other tissues or the body.

22. Matrix: Nonliving, extracellular material, separates cells of the tissue.
Allows tissue to bear weight, tension, and endure abuses

23. Connective tissues develop from embryonic tissue known as MESENCHYME

24. CELLS
1. Fibroblasts: produce fibers and carbs and protein constituents of matrix

25. Chondroblast: Cartilage
Osteoblast: Bone
Hemocytoblast: Blood

26. FIBERS
Collagen
Most abundant
White fibers
Tough, inelastic

27. FIBERS Reticular Finely branched Composed of collagen
EX. Basement membrane, small blood vessels

28. FIBERS Elastic Yellow fibers Elastin (protein)
Ex. Skin, lungs, vessels

29. Connective Tissue Proper Two subclasses:
Types of C.T.
Connective Tissue Proper
Two subclasses:

30. Loose connective (areolar, adipose, reticular)
Dense connective (Dense regular, Dense irregular, Elastic)

31. Dense regular connective

32. Elastic Cartilage

33. Cartilage: tough yet flexible, avascular
Chondrocytes
Perichondrium: well-vascularized dense irregular connective tissue membrane

34. Bone Main supporting tissue Compact bone & spongy bone
Well supplied by blood vessels

35. Blood Blood and lymph are circulating connective tissues
Red marrow-blood cells

37. Skeletal: Voluntary control, attached to bone.
Muscle Tissue
Skeletal: Voluntary control, attached to bone.

39. Cardiac: Involuntary, Heart, branched cells joined end to end.

41. Smooth: Involuntary
Lining of organs, vessels

43. Nervous Functions Receive stimuli Transmit info
Control action of muscle and glands
