| Question | Answer |
|---|---|
| What are the four basic tissue types? | epithelium, nervous, muscle, connective |
| What are the main functions of epithelium? | protection, absorption, filtration, excretion, secretion, and sensory reception |
| 5 characteristics of epithelial tissues | Polarity, supported by connective tissues, regeneration, specialized contacts, avascular but innervated |
| What is the basement membrane made up of? | Basal lamina and reticular lamina |
| What is the bond between epithelial and connective tissue? | connective tissue shares its blood supply and nutrients with epithelial tissue through diffusion |
| How is stratified epithelia named? | the cell is named according to the shape in the apical layer |
| What is simple epithelia involved in? | absorption, secretion, and filtration processes |
| Rapid diffusion is a priority in what classification of epithelia? | simple squamous |
| Where is mesothelium? | A simple squamous that lines serous membranes |

| Where is simple cuboidal found? | kidney tubules, ducts and secretory portions of small glands, ovary surface |
| What is the difference between cilia and microvilli? | Cilia is hair-like and microvilli are projections of the cell to increase surface area |
| What are the functions of simple columnar epithelium? | absorption, secretion of mucus, enzymes, and other substances |
| Where is simple columnar found? | nonciliated types line most of the digestive tract (stomach to rectum), gallbladder, and excretory ducts of some glands, ciliated variety lines small bronchi, uterine tubes, and some regions of the uterus |
