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 |
