Chapter 5 Tissues Flashcards
Cells of similar type and function clustered into layers, sheets, or groups
Tissues
Four types of tissue
Epithelial, Connective, Muscle, Nervous
Tissue that covers and lines
Epithelial tissue
Tissue that provides support
Connective tissue
Tissue that enables movement
Muscle tissue
Tissue that controls work
Nervous tissue
Side of the cell that faces the lumen
Apical surface
Side of the cell that faces the underlying connective tissue
Basal surface
Epithelial cells; vascular or avascular?
Avascular
Foundation of the epithelial cell
Basement membrane
What is the purpose of a brush border?
Increases surface area thus absorptive ability
Waterproof substance that protects epithelial cells
Keratin
Fusion of the outermost layer of the plasma membranes of adjoining cells; matrix filled space is lost
Tight junction
Strong, welded plaque that connects the plasma membranes of adjacent cells
Desmosome
Cells connected by tubular channel proteins
Gap junctions
Single layer, found lining surfaces involved in passage of gas or liquid
Simple squamous epithelia
Epithelium that lines the pleural, pericardial, and peritoneal cavities
Mesothelium
Epithelium that lines blood and lymphatic vessels
Endothelium
Single layer, cubic cells
Simple cuboidal epithelium
Single layer, elongated and packed together
Simple columnar epithelium
The type of cell whose apical surface is blanketed by dense microvilli; maximizes absorption
Absorptive cell
Wine glass shape, manufacture and store lubricating mucus
Goblet cells
Multiple layers, occurs in areas of the body that are subject to mechanical and chemical stress
Stratified squamous epithelium
Multiple layers, cuboidal cells; found along excretory ducts
Stratified cuboidal epithelium
Multiple layers, rare; found along select parts of the respiratory, reproductive, digestive systems
Stratified columnar epithelium
Glands that do not have ducts; secretions distributed throughout the body
Endocrine glands
Glands that possess ducts
Exocrine glands
Most abundant type of tissue by weight, found everywhere in the body; vascularized
Connective tissue
