Histology and General Pathology Flashcards
Aggregated, polyhedral, small amount ecm, lines surface or body cavity & glandular secretion
Epithelial Tissues
Fixed/wandering, abundant ecm, support & protection
Connective Tissues
Elongated and contractile, moderate ecm, contractions & body movements
Muscle Tissues
Elongated cells with extremely fine processes, very small amount ecm, & transmission of nerve impulses
Nervouse Tissues
Major cells in the skin
Keratinocytes
Cell Morphology/Cell Shape
Squamous
Cuboidal
Columnar
Number of Cellular Layers
Simple
Stratified
Pseudostratified
Single layer of flat thin cells found where diffusion or filtration takes place
Simple Squamous
Single layer of cube-shaped cells that carry out active transport
Simple Cuboidal
Single layer of tall narrow cells, contain GOBLET CELLS which produce mucus for lubrication
Simple Columnar
Multiple layers of cells that are CUBOIDAL in the basal layer and progressively flattened toward the surface
Pseudostratified Columnar
Multiple layers of cube-shaped cells
Stratified Cuboidal
Multiple layers of tall and thin cells
Stratified Columnar
Highly modified appear CUBOIDAL when the organ or tube is not stretched SQUAMOUS when the tube or organ is stretched by fluid
Transitional Epithelium
Forms the serosa
Simple Squamous
