Tissues
| Term | Definition |
|---|---|
| adipose tissue | type of loose connective tissue dominated by fat cells |
| areolar tissue | type of loose connective tissue that lies beneath almost all epithelia |
| chondrocytes | cartilage-forming cells |
| columnar epithelium | epithelial tissue composed of cells having a tall columnar shape |
| connective tissue | the most widespread, and the most varied, of all the tissues; serves to connect the body together and to support, bind, or protect organs |
| cuboidal epithelium | epithelial tissue consisting of cells having a cube-like shape |
| endocrine gland | a gland that secretes its product, called a hormone, directly into the blood stream |
| epithelium | the layer of cells forming the epidermis of the skin and the surface layer of mucous membranes |
| exocrine gland | a gland that secretes its product into a duct, which then empties onto a body surface or inside a body cavity |
| fibroblasts | cells that secrete collagen, which forms scar tissue inside a wound |
| fibrosis | the repair and replacement of damaged tissue with connective tissue, mainly collagen |
| glandular epithelium | type of epithelium consisting of glands that secrete a particular substance |
| goblet cell | modified columnar cell containing secretory vesicles that produce large quantities of mucus |
| grandulation tissue | newly formed tissue inside a wound |
| mucous membrane | epithelial membrane that lines body surfaces that open directly to the body's exterior |
| muscle tissue | tissue consisting of contractile cells or fibers that effect movement of an organ or body part |
| nervous tissue | tissue with a high degree of excitability and conductivity that make up the nervous system |
| osseous tissue | bone tissue |
| reticular tissue | tissue consisting of loose network of reticular fibers and cells; forms the framework of the spleen, lymph nodes, and bone marrow |
| serous membrane | membrane composed of simple squamous epithelium resting on a thin layer of areolar connective tissue; lines some of the closed body cavities and also covers many of the organs in those cavities |
| squamous epithelium | epithelial tissue consisting of thins, flat cells |
| stem cells | specialized cells that can differentiate into many different types of cells |
| tissue | groups of similar cells that perform a common function |
