Flashcards do conjunto (9)
- 1Embryonic Tissue- 2 Stem cell types:
embryonic (produces OTHER cells)
adult (produces NEW cells)
- Large nucleus & extension of cytoplasm - 2Epithelial Tissue- Lines surfaces of the body
- squamous
columnar
ciliated columnar
cuboidal
stratified - 3Squamous Epithelium (structure & location)- Flat cells
- No intercellular spaces/substances
- 1 flat nucleus
- mouth interior
alveoli walls - 4Squamous Epithelium (functions)- Thin cells = diffusion
- Smoothens internal surfaces
- reduces friction - 5Cuboidal Epithelium (structure & location)- cubic/rounded cells
- no intercellular spaces
- 1 nucelus
- glands
excretory structures (thyroid gland)
- 6Columnar Epithelium (structure & location)- elongated cells
- oval nucleus
- Goblet cells (mucous)
- Mucous membrane of digestive tract/ urethra & sperm duct
- 7Ciliated Columnar Epithelium (functions)- all cells can have
- Expels mucous containing unwanted particles
- Moves egg cell down Fallopian tubes
- 8Layered Epithelium (location)- Surface of skin
- 9Layered Epithelium (structure)- Several shapes & sizes
- Layers
- Cells formed in their deeper layer, then pushed upwards
- Flat/hard with maturity
- Contain KERATIN
