Embryonic Tissue's 3 Germ Layers | Endoderm, Mesoderm, Ectoderm |

Mesoderm | Middle germ layer that forms muscle, bone, and blood vessels |
Epithelium | Covers body, forms glands |
3 Epithelial Surfaces | free, basal, and lateral |
Basal | Connected to basement membrane |
Lateral | Side surface of cells and organs |
Free | Not connected to anything |
Avascular | Without blood vessels |
Mitosis | Replication of cell |
Basement Membrane | Formed by secretions of both epithelium and connective tissues. Acts as filter and "glue." Absorbs oxygen and secretes waste. |
Types of epithelium based on # of layers | Simple, stratified, and pseudo-stratified |
Simple | One layer, filters blood, toward surface like skin |
Stratified | More than 1 layer of cell. Protective layer. |
Pseudo-stratified | 1 simple layer, but each cell is long and weird |
Cuboidal | cube shaped cells |
Columnar | Column shaped cells |
Squamous | Flat and scaley |
Epithelium type based on shape | Cuboidal, columnar, squamous |
Microvilli | Increase surface area of absorption or secretion |
Cilia | Moves material across cell surface |
Transitional Epithelium | lines bladder and ureters, allowing expansion |
Goblet Cell | Columnar and produces mucus |
