| 1. | adipocytes | lipid storage cells |
| 2. | adipose tissue | specialized areolar tissue rich in stored fat |
| 3. | anchoring junction | mechanically attaches adjacent cells to each other or to the basement membrane |
| 4. | apical | that part of a cell or tissue which, in general, faces an open space |
| 5. | apocrine secretion | release of a substance along with the apical portion of the cell |
| 6. | apoptosis | programmed cell death |
| 7. | areolar tissue | (also, loose connective tissue) a type of connective tissue proper that shows little specialization with cells dispersed in the matrix |
| 8. | astrocyte | star-shaped cell in the central nervous system that regulates ions and uptake and/or breakdown of some neurotransmitters and contributes to the formation of the blood-brain barrier |
| 9. | atrophy | loss of mass and function |
| 10. | basal lamina | thin extracellular layer that lies underneath epithelial cells and separates them from other tissues |
| 11. | basement membrane | in epithelial tissue, a thin layer of fibrous material that anchors the epithelial tissue to the underlying connective tissue; made up of the basal lamina and reticular lamina |
| 12. | cardiac muscle | heart muscle, under involuntary control, composed of striated cells that attach to form fibers, each cell contains a single nucleus, contracts autonomously |
| 13. | cell junction | point of cell-to-cell contact that connects one cell to another in a tissue |
| 14. | chondrocytes | cells of the cartilage |
| 15. | clotting | also called coagulation; complex process by which blood components form a plug to stop bleeding |
| 16. | collagen fiber | flexible fibrous proteins that give connective tissue tensile strength |
| 17. | connective tissue membrane | connective tissue that encapsulates organs and lines movable joints |
| 18. | connective tissue proper | connective tissue containing a viscous matrix, fibers, and cells. |
| 19. | connective tissue | type of tissue that serves to hold in place, connect, and integrate the body's organs and systems |
| 20. | cutaneous membrane | skin; epithelial tissue made up of a stratified squamous epithelial cells that cover the outside of the body |
| 21. | dense connective tissue | connective tissue proper that contains many fibers that provide both elasticity and protection |
| 22. | ectoderm | outermost embryonic germ layer from which the epidermis and the nervous tissue derive |
| 23. | elastic cartilage | type of cartilage, with elastin as the major protein, characterized by rigid support as well as elasticity |
| 24. | elastic fiber | fibrous protein within connective tissue that contains a high percentage of the protein elastin that allows the fibers to stretch and return to original size |
| 25. | endocrine gland | groups of cells that release chemical signals into the intercellular fluid to be picked up and transported to their target organs by blood |
| 26. | endoderm | innermost embryonic germ layer from which most of the digestive system and lower respiratory system derive |
| 27. | endothelium | tissue that lines vessels of the lymphatic and cardiovascular system, made up of a simple squamous epithelium |
| 28. | epithelial membrane | epithelium attached to a layer of connective tissue |
| 29. | epithelial tissue | type of tissue that serves primarily as a covering or lining of body parts, protecting the body; it also functions in absorption, transport, and secretion |
| 30. | exocrine gland | group of epithelial cells that secrete substances through ducts that open to the skin or to internal body surfaces that lead to the exterior of the body |
