Connective Tissue Flashcards
Maintain the form of organs throughout the body
Connective tissue
Provide a matrix that supports and physically connects other tissues and cells together in organs
Connective tissue
__________ of connective tissue gives metabolic support to cells as the medium for diffusion of nutrients and waste products
Interstitial fluid
Connective tissue Originate from embryonic
mesenchyme
Major constituent of connective tissue is the
extracellular matrix (ECM)
Fibers
Ground substances
- complex of anionic, hydrophilic proteoglycans, glycosaminoglycans (GAGs), and multi-adhesive glycoproteins (laminin, fibronectin, and others)
Ground substance
(such as collagens and elastic fibers)
Protein fibers
consists of closely aggregated cells connected firmly to one another in the form of cellular sheets that line the interior of hollow organs and cover the body surface
EPITHELIAL TISSUE
composed of epithelial cells and a small amount of extracellular matrix
EPITHELIAL TISSUE
arranged cellular sheets either in single or multiple layers
EPITHELIAL TISSUE
avascular except stria vascularis of the inner ear
EPITHELIAL TISSUE
forms the covering of various organs and thus is the outermost tissue in most organs
EPITHELIAL TISSUE
various organs like skin, buccal cavity, the lining of blood vessels, body cavities, glands, and their
ducts
EPITHELIAL TISSUE
less abundant than connective tissue
EPITHELIAL TISSUE
made up of cells, fibers, and gel-like substances that supports and gives structure to the body
CONNECTIVE TISSUE
composed of different cells and a
larger amount of extracellular matrix
CONNECTIVE TISSUE
scattered throughout the matrix in no particular arrangement
CONNECTIVE TISSUE
vascular except for cartilages
poorly vascular-tendons and ligaments
CONNECTIVE TISSUE
usually present underneath the epithelial tissue
CONNECTIVE TISSUE
forms the bones, cartilages, adipose tissue, reticular tissue, and the blood
CONNECTIVE TISSUE
most abundant animal tissue
CONNECTIVE TISSUE
Elastic fiber
Collagen fiber
Reticular fiber
Protein fibers
Resident cells
Mesenchymal cell
Macrophage
Adipocyte
Fibroblast
Product of fibroblasts
Extracellular fibers and ground substance
Product of Plasma cells
Antibodies
Responsible for Various immune/defense functions
Lymphocytes (several types)
Responsible for: Modulate allergic/vasoactive reactions and defense against parasites
Eosinophilic leukocytes
ANTIPARASITIC!!!!!!
Responsible for Phagocytosis of bacteria
Neutrophilic leukocytes
