1. Epithelial and Muscle Twizz This is not enough! Study the notes!

2. What is a tissue?

3. Group of similar cells performing a similar function Histology – microscopic study of tissues Structure determines function!!!

4. 4 types of tissues?

5. Connective Epithelial Nervous Muscle

6. Common features of Epithelial

7. Fit tightly together (very little extra space) Free surface Basement Membrane Avascular Highly innervated

8. General Functions of Epithelial

9. Protection Barriers Diffusion Secretion Absorption

10. to protect

11. where diffusion is important where tissues are involved in secretion and absorption: larger cells because of the machinery of production, packaging, and energy requirements

14. “ciliated” literally = eyelashes (see next page)
