Epithelial | Covers exterior surface of the body, lines internal cavities and passageway and forms contain gland |
Apical | Surface of the cell |
Basal | Bottom of the cell |
Basal lamina | Provides an attachment site for the epithelium separating it from the underlying connective tissue |
Epithelial tissue classification | Shape of their cell and number of layers |
Matrix | Crisscrossed by protein fibers |
Ground substance | It is fluid, but could also be mineralized and solid(bone) |
3examples of fixed cell | Fibroblasts-produce the fibers tissue, adipocytes-store liquid , and mesenchymal adult stem cell |
Apocrine glands | Sweat |
Sudoriferous gland | Sweat |
Sebaceous gland | Oil |
Exocrine gland | Through ducks that lead to the epithelial surface |
Endocrine gland | Secrets hormones, that are ductless so to release secretion directly into the surrounding tissue |
Cilia | Projection of the apical cell membrane that help move fluid
-help circulate cerebrospinal
-in air ways they help get rid of dust |
Highly cellular mean | It has a little or no extra cellular material present between lots of cell |
3germ layers | Ectoderm - becomes the epidermis, gland on the skin
Mesoderm- becomes the connective tissue
Endoderm - becomes lining of the air ways and digestive system except mouth |
Stem cells | Unspecialized cell that can give rise to one or more cells different type like nervous or blood cell |
