| Question | Answer |
| Embryonic Tissue | - 2 Stem cell types: embryonic (produces OTHER cells) adult (produces NEW cells) - Large nucleus & extension of cytoplasm |
| Epithelial Tissue | - Lines surfaces of the body - squamous columnar ciliated columnar cuboidal stratified |
| Squamous Epithelium (structure & location) | - Flat cells - No intercellular spaces/substances - 1 flat nucleus - mouth interior alveoli walls |
| Squamous Epithelium (functions) | - Thin cells = diffusion - Smoothens internal surfaces - reduces friction |
| Cuboidal Epithelium (structure & location) | - cubic/rounded cells - no intercellular spaces - 1 nucelus - glands excretory structures (thyroid gland) |
| Columnar Epithelium (structure & location) | - elongated cells - oval nucleus - Goblet cells (mucous) - Mucous membrane of digestive tract/ urethra & sperm duct |
| Ciliated Columnar Epithelium (functions) | - all cells can have - Expels mucous containing unwanted particles - Moves egg cell down Fallopian tubes |
| Layered Epithelium (location) | - Surface of skin |
| Layered Epithelium (structure) | - Several shapes & sizes - Layers - Cells formed in their deeper layer, then pushed upwards - Flat/hard with maturity - Contain KERATIN |
