| Tissue Type -- Internal Communication - Brain, Spinal Cord, Nerves |
|
|
Term
|
Definition
| Tissue Type -- Contracts to cause movement - Muscles attached to bones (Skeletal), Muscles of heart (Cardiac), Muscles of walls of hollow organs (Smooth). |
|
|
Term
|
Definition
| Tissue Type -- Forms boundaries between different environments, protects, secretes, absorbs, filters - Lining of digestive tract organs and other hollow organs, Skine surface (Epidermis) --- Avascular (No blood vessels) and Innervated (Supplied by nerve fibers) |
|
|
Term
|
Definition
| Tissue Type -- Supports, protects, binds other tissues together - Bones, Tendons, Fat and other soft padding tissue. |
|
|
Term
|
Definition
| Groups of woven cells that are similar in structure and perform a common or related function. |
|

Term
|
Definition
| (All epithelia have) Upper free surface exposed to the body exterior or the cavity of an internal organ, and a lower attached basal surface. |
|
|
Term
|
Definition
| The two surfaces differ in both structure and function. For this reason, we say that epithlia exhibit apical-basal polarity. |
|
|
Term
|
Definition
| Fingerlike extensions of the plasma membrane |
|
|
Term
|
Definition
| Adjacent to the basal surface of an epithelium, thin supporting sheet. Noncellular, adhesive sheet consists largely of glycoproteins secreted by the epithelial cells plus some fine collagen fibers. Acts as a selective fiber that determines which molecules diffuse from the underlying connective tissue. |
|
|
Term
|
Definition
| Layer of extracellular material containing a fine network of collagen protein fibers that belongs to the underlying connective tissue |
|
|
Term
|
Definition
| Basal Lamina and Reticular Lamina form this. |
|
|
Term
|
Definition
| Consists of one or more cells that make and secrete a particular product. |
|
|
Term
|
Definition
| Product of a gland -- Aqueous (Water-based) fluid that usually contains proteins, but there is variation. Ex - Some glands release lipid of steroid rich secretion. |
|
|
Term
|
Definition
| Eventually lose their ducts, ductless glands -- Produce hormones. Most are stucturally diverse, commonly compact multicellular organs. |
|
|
Term
|
Definition
| Secrete onto the body surgace or into body cavities. Unicellular glands do so directly (by exocytosis). Multicellular do so via an epithelium-walled duct that transports the secretion to the epithelial surface. |
|
|
Term
| Unicellular Exocrine Glands |
|
Definition
| Mucous cells and goblet cells. Produce mucin. |
|
|
Term
|
Definition
| A complex glycoprotein that dissolves in water when secreted. |
|
|
Term
| Multiccellular Exocrine Glands |
|
Definition
| Structurally more complex. Two basic parts -- An epithelium-derived duct and a secretory unit (Acinus) |
|
|
Term
|
Definition
| Surrounded by supportive connective tissue and supplies it with blood vessels and nerve fibers. Forms a fibrous capsul that extends into the gland and divides it into lobes. |
