Epithelial Tissue Flashcards
Histology
The study of tissues and how they are arranged into organs
What are the four primary tissue classes
Epithelial Tissue
Connective Tissue
Nervous Tissue
Muscular Tissue
Describe some characteristics of Epithelium tissue
-Contain a basement membrane, basal surface, and apical surface
-tightly packed
-one or more layers
-covers organ surfacews
-lines body cavities
-forms epidermis
What is this arrangement
Simple
What is this arrangement
Pseudostratified
What is this arrangement
Stratified
What is this shape
Squamous
What is this shape
Cuboidal
What is this shape
Columnar
Characteristic, Function, and Location of Simple Squamous
Characteristic: One layer of thin flat cells
Function: Diffusion
Location: Respiratory membrane of the lungs
Characteristic, Function and Location of Simple Cuboidal
Character: One layer of cube like cells
Function: Selective secretion and absorption
Location: Kidney
Characteristic, Function, and Location of Simple Columnar
Characteristic: One layer of tightly packed column cells
Function: Absorb and protect
Location: Small Intestine
Characteristic, Function, and Location of Pseudostratified Ciliated Columnar
Characteristic: Columns and goblet cells in one layer but all do not touch the basement surface
Function: Protect and clean the airway
Goblet Cells: Contain mucus
Motile Cilia: Moves mucus and dirt out of the airway
Location: Trachea
Stratified Squamous (Keratinized)
Function: Protect against water loss
Location: Skin
Stratified Squamous (No Keratin)
Function: Protect against abrasion
Location: Oral Cavity and Vagina
