Tissue types of the body (Epithelium (Locations. Skin,Body linings…

- - - - Epithelium Characteristics ~ Cells fit closely together,lower surface has basement membrane,A vascular(no blood supply)
        
        Number of cell layers,
        Stratified~more that one
        Simple~one layer
        
        Shape of cells~ squamous is flattened
        ~Cuboid is cube shaped
        Columnar-Columnar like
        
        simple squamous ~ Single layer of flat cells
        ~usually forms membranes
        ~lines body cavities ,lungs and capillaries
        
        Simple cuboidal
        ~single layer of cube-like Cells
        Common in glands and thier ducts
        ~forms walls of kidneys tubules
        ~covers the ovaries
        
        simple columnar
        ~Single layer of tall cells
        ~Often looks like a gobbet cell layer which produces mucus
        ~lines digestive tract
        
        Pseudo stratified
        ~single layer but some cells are shorter than others
        ~Absorption and secretion
        ~looks like double cell layer
- - - - Characteristic
        Ava scalar,Extracellular matrix
        
        Matrix comprised of ground substance and fibers
        
        Ground substance is mostly water along with adhesion protein and polyacrylamide molecules
        
        Fibers
        Producted by the cells
        
        Collagen fibers
        
        Elastic fibers
        
        Reticular fibers
        
        Bone
        ~found in lacunae(cavities
        ~hard matrix of calcium salts
        ~large number of collage fibers
        
        Dence connective tissue
        ~Main matrix element is collage fibers
        ~Cells are fibrillates
        ~tendons and ligaments
        
        Cartilages
        
        hyaline Cartilage
        ~Abundant collagen fibers
        ~Rubbery matrix
        ~Entire fetal skeleton is Aline cartilage
        
        Elastic cartilage
        ~Provides elasticity
        
        Fibrocartilage
        ~Highly compressable
        Forms cussions between vertebre
        
        Loose connective tissue
        ~
        
        Areolar
        ~soft tissue
        ~contains all fiber types
        ~can soak up fluid
        
        Dence Connective tissue
        
        Adipose
        ~Matrix is an alveolar tissue in which fat globules pre dominate
        ~insulates the body
        ~Protects some organs
        ~serves as a site of fuel storge
