Definition
| cells lie close together (very little intercellular material; covers surfaces or lines cavities, external or internal; can be glandular, sensory, or reproductive |

|
Term
| simple squamous epithelium |
|
Definition
| single layer of flat cells which form thin, smooth membranes. Lining of ducts, blood vessels, body cavities, air sacs, etc. |
|
|
Term
| stratified squamous epithelium |
|
Definition
| contains several layers of cells, the top layer flat and the lower layers less flat the deeper they are. |
|
|
Term
| simple cuboidal epithelium |
|
Definition
| "cube-like" cells; single-cell thick layers; lines ducts for kidneys and glands |
|
|
Term
| simple columnar epithelium |
|
Definition
| cells taller than they are wide; mostly 1 cell thick; line the entire digestive tract and the windpipe. in the windpipe, cilia are attached to the end of the cells to move foreign particles to the throat. |
|
|
Term
|
Definition
| large amounts of non-cellular materials outside the cell membranes; cells do not lie close together, but are scattered throughout the matrix. connect and support parts of the body |
|
|
Term
|
Definition
| composed of chondrocytes scattered in the matrix either single or paired, places where there is potential for chondrocytes are called lacunae |
|
|
Term
|
Definition
| main tissue associated with the skeleton |

|
Term
|
Definition
| basic unit if compact bone tissue |
|
|
Term
|
Definition
| large circular space in the center of the osteon which is occupied by blood vessels that service the osteon |
|
|
Term
|
Definition
| concentric rings of non-cellular material spaces that surround the osteonic canal |
|
|
Term
|
Definition
| cells in bone that produce the matrix |
|
|
Term
|
Definition
| spaces in bone normally occupied by osteocytes; found on the lamellae |
|
|
Term
|
Definition
| small projections connecting lacunae on different lamellae; allow neighboring osteocytes to share nutrients |
|
|
Term
| loose or aerolar connective tissue |
|
Definition
| loosely arranged, fibroelastic tissue; main features are variety of cells and fibers; cells called fibroblasts; fibers called collagen fibers (larger, for rigidity and toughness) and elastic fibers (thinner for flexibility) |
|
|
Term
|
Definition
| characterized by fat vacuoules; the nucleus and the cytoplasm are smashed to the plasma membranes |
|
|
Term
|
Definition
| made up of plasma liquid, erythrocytes (donut shaped cells), leukocytes (nucleated cells used to fight pathogens), and thrombocytes (cell fragments that stick to form clots) |
|
|
Term
|
Definition
| composed of enlongated cells specialized for the function of contraction, movement |
|
|
Term
|
Definition
| associated with internal organs, walls of stomach and intestines; cells are spindle shaped |
|
|
Term
|
Definition
| composed of long fiber cells; striated due to arrangement of proteins actin and myosin; single cells contain more than one nucleus |
|
|
Term
|
Definition
| striated, branched tissue around the heart. cells are connected by their intercalated discs which allow for cells to be electrically connected |
|
|
Term
|
Definition
| composed of cells called neurons that facillitate transmission of nervous information |
