| tissue | a group of similar cells that perform a specific function |
| differentiation | tissue that has the ability to be very specialized |
| 4 tlissue types | epithelium, connective, muscle, nervous |
| epithelial tissue | covers, lines and forms glands |
| connective tissue | binds and supports; most abundant tissue |
| muscle tissue | movement, contraction |
| nervous tissue | transmits messages & impulses; most specialized tissue |
| matrix | found in connective tissue; consists of ground substance and fibers |
| classificatoin of epithelial tissue | cell shape and arrangement of layers |
| quick repair of epithelial tissue | due to high mitotic rate |
| keratin | waterproofing protein foun in the skin |
| transitional epithelium | has ability to stretch; bladder |
| basement membrane | located between epithelial and connective tissue |
| endocrine glands | ductless; secrete directly into blood; salivary glands |
| exocrine glands | secrete substance trhough a duct; tear duct |
| adipose tissue | functions in insulation and energy storage |
| fibroblast | found in connective tissue; secretes matrix and fibers |
| avascular tissue | epithelial tissue; cartilage |
| vascular tissue | most connective tissue |
| tendons | made of dense connective tissue |
| hyaline cartilage | glassy appearance; provides movement at joints |
| apple body shape | extra body fat on torso;increases risk of heart disease |
| pear body shape | extra body fat in hip area; increases risk of heart disease |
| erythrocytes | RBC's; important in oxygen transport |
| leukocytes | WBC's; important in immunity |
| platelets | thrombocytes; important in clotting |
| mucous membrane | open to exterior; GI tract |
| serous membranes | line closed cavities; lungs |
| cutaneous membranes | membranes of the skin |
| subcutaneous | refers to under the skin |
| uninucleated tissue | cardiac tissue; smooth tissue |
| striated tissue | skeletal and cardiac tissue |
| nonstriated tissue | smooth muscle |
| neurons | nerve cells that transmit impulses |
| neuroglia | cells of nervous tissue that support neurons; does not conduct nerve impulses; site for tumors |
| axon | structure that conducts impulses away from the cell |
| dendrite | structure of a nerve that conducts impulses toward the cell |
| pleurisy | inflammation of pleural membrane of lungs |
| ciliated epithelial cells | move substances through an area; respiratory system |
