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
