| Word | Definition |
|---|---|
| Histology | study of tissues |
| Pathology | study of diseased tissues |
| Epithelial Tissue | Function is Protection and Secretion |
| Connective Tissue | Function is Support |
| Muscular Tissue | Function is Movement |
| Nervous Tissue | Function is Responsiveness and Coordination |
| Cellularity | lots of cells on slide |
| Specialized contacts | held by desmosomes and tight junctions |
| Polarity | one free surface |
| Endothelium | Inner tube lining |
| Mesothelium | Body cavity lining |
| basement membrane | where epithelial tissue hooks to connective tissue |
| apical | top |
| basal | bottom |
| innervated | feel it |
| avascular | no blood |
| regeneration | epithelial best type of tissue for |
| Epithelial Named For | Shape and Arrangement |
| Squamous | Scalelike, flattened |
| Cuboidal | Cube, large nucleus in middle |
| Columnar | Nuclei at bottom |
| Simple | 1 layer |
| Stratified | 2 or more stacked layers |
| Pseudostratified | single layer looks multiple different heights |
| Unicellular | one celled |
| multicellular | more than one cell |
| Gland | any organ that secretes |
| Connective Tissue | Made Up Of ECM |
| CT | Most Abundant and Widely Distributed |
| Extracellular Matrix | Secreted By Cells, ground substance and fibers |
| Collagen | White protein, strength, tendons |
| Elastin | Yellow, elasticity, ear |
