Endoderm
Gives rise to mucous membranes of the viscera and digestive glands
3 primary Germ Layers
Endoderm, Mesoderm, Ectoderm
Mesoderm
Muscle and bone, mesenchyme
Middle layer
Ectoderm
Epidermis and nervous system
Outer layer
Interstitial Fluid
Matrix material located outside the cells
Mesenchyme
Gives rise to muscle and bone
Epithelial Tissue
Covers body surfaces, lines body cavities , forms internal and external lining of many organs, constitutes most gland tissue, closely packed cells
Basement membrane
Adheres epithelial tissue to underlying connective tissue
What type of epithelium makes up air sacs of lungs, inner lining of heart and blood vessels, and serous membranes of the viscera?
Simple squamous epithelium
Urothelium
Stratified epithelium specialized to allow stretching, found lining linen of urinary bladder
Which epithelium resists abrasion and prevents entrance of pathogens into underlying tissue?
Stratified squamous epithelium
Rare and only seen where 2 other epithelia meet
Stratified Columnar Epithelium
Fills the spaces between tissues and binds tissues to one another, supports and protects organs
Connective Tissue
