Name the 4 primary classes adult tissues are classified. | Epithelial, Connective, Nervous & Muscular |
What are examples of where you find epithelial tissue? | Epidermis, Digestive lining, Liver & Other glands |
What are examples of where you find Connective tissue? | Tendon, ligaments, cartilage, bone & blood |
What are examples of where you find nervous tissue? | Brain, spinal cord, nerves |
What are examples of where you find muscular tissue? | Skeletal, Heart, Viscera Walls |
What is made up of two or more types of tissues? | Organ |
Define: Histology | Study of tissues & how they are arranged into organs |
Define: Tissue | Similar cells & cell products that work together to perform a specific structural or physiological role in an organ. |
Define: Epithelial Tissue | Tissues composed of layers of closely spaced cells that cover organ surfaces, form glands, & serve for protection, secretion, & absorption. (Pg. 144) |
Define: Connective Tissue | Tissue w/ usually more matrix than cell volume, often specialized to support, bind, & protect organs. (Pg. 144) |
Define: Nervous Tissue | Tissue containing excitable cells specialized for rapid specialized for rapid transmission of coded information to other cells. (Pg. 144) |
Define: Muscular Tissue | Tissue composed of elongate, excitable muscle cells specialized for contraction. (Pg. 144) |
Name the 3 embryonic germ layers and where are they found. | Ectoderm (epidermis, nervous system), Mesoderm (muscle, bone, blood), Endoderm (digestive & respiratory tracts and digestive glands) |
What distinguishes epithelial tissue from other tissues? | |
True / False: Epithelial tissue is supplied by blood vessels. | False |
Name the 2 broad categories of epithelial tissue. | Simple & Stratified |
Each category of epithelial tissue there are 4 types, name the 3 types each category has in common and indicate the 4th type for each.. | 3 Common - Squamous, Cubodial, Columnar 4th for Simple = pseudostratified columnar 4th for Stratified = Transitional |
Define: Matrix | Extracellular material composed of: - fibrous proteins - interstitial fluid (tissue gel) |
Epithelial tissue is anchored by a _________________ __________________. | basement membrane made of Collagen, glycoproteins called Laminin & Fibronectin, and a large protein-carb complex called Heparin Sulfate |
Where is epithelial tissue usually found? | upper surfaces exposed to the environment & lines body cavities |
What type of tissue provides nourishment & waster removal for the epithelial layer? | connective tissue |
Describe the properties that most connective tissues have in common. |
