1. Tissues Distinguish the four tissue types. - epithelial, connective, nervous and muscle

2. Case: Neonatal Jaundice

3. Draw an epithelium, labeling cell junctions and the apical & basal membranes. Explain the role of different epithelial types and different junction types. Epithelial tissue objectives

4. Epithelia - cover body surfaces and line body cavities (lumen), form glands Functions of epithelial cells include: * movement of materials in and out of the body. * protection of the internal environment against the external. * secretion of a product.

5. Characteristics of epithelial cells: 1.They are contiguous (attached to one another). 2.The cells rest on the basement membrane, an extracellular matrix they produce. 3.They often have two different sides - apical side : towards the lumen - basal side : towards extracellular fluid * Note these cells are polarized, meaning the two cell surfaces have different functions.

6. Types of epithelial tissues: - exchange - transporting - protective - ciliated - secretory exocrine - mucus, saliva, earwax, milk, oil, digestive enzymes endocrine - hormones

7. 1.&2. Smooth muscle 3. Transporting epithelium 4. Secretory epithelium (goblet cell) 5. Lumen Digestive tract - example organ with multiple tissues

8. Connective tissue objectives –List the basic components of connective tissue and their contribution to tissue function. –Name and describe the different connective tissue types.

9. Composed of… specialized cells and their extracellular products Connective tissue type depends on… 1.type of cell specialization 2.type and arrangement of protein fibers 3.type of ground substance Connective tissues support, connect, protect, strengthen and insulate other tissues.

10. collagen - gives strength elastin - gives flexibility Two fiber types in connective tissue

11. Loose connective tissue

12. Dense regular connective tissue

13. Cartilage Adipose (fat) Blood Bone

14. For Monday… Review epithelial and connective tissue Begin Chapter 5 - cell membrane components and movement across membranes
