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
Functions in covering and secretion
Simple Cuboidal
Functions in protection, lubrication, absorption, and secretion
Simple Columnar
Nuclei of these are cells are at different levels and appear stratified
Pseudostratified Columnar
Found on sites that receive a good deal of abuse or friction
Stratified Squamous
Forms lining of organs that accommodates fluctuations in volume of fluid
Transitional Epithelium
Alveoli of lungs
Endothelium
Mesothelium
Bowman’s Capsule
Loop of Henle
Simple Squamous
Ovarian surface
Rete testis
Kidney Tubules
Small ducts of exocrine glands
Simple cuboidal
Lining of intestine from stomach to anus
Gallbladder
Endocervix
Simple Columnar
Lining of nasal cavity and nasal sinuses
Trachea
Pseudostratified Columnar

Cornea
Non-Keratinized (Stratified Squamous)
Sweat Gland Ducts
Ovarian Follicles
Stratified Cuboidal
Mammary Gland Ducts
Larynx
Conjunctiva
Stratified Columnar
Lining of the Urinary Bladder
Transitional Epithelium
Often called as ductless glands
