- 2. characteristic of epithelial tissue, cells having apical surface and basal surface where they attach to underlaying cells/tissues
- 3. characteristic of epithelial tissue, composed almost entirely of cells with little extracellular matrix, bound together by intercellular junctions
- 4. composed of cells called fibers
- 8. same size on all sides, nucleus is centrally located
- 10. group of cells performing similar functions
- 11. cartilage supporting connective tissue, most common, found at ends of bones that articulate with each other, in trachea, larynx, and nose
- 13. taller than wide, nucleus is oval and located in basal region of cell
- 16. fluid connective tissue, comprised of plasma, erythrocytes, leukocytes, and platelets
- 17. type of nervous tissue, capable of initiating and conducting electrical activity throughout the body
- 21. tissue that operates communication
- 23. substance produced by cells of specific tissue containing protein fibers, salts, water, and dissolved macromolecules located outside of the cell
- 25. type of epithelial layer, two or more layers of cells that don't all have apical surfaces or are attached to basement membrane
- 26. flattened, similar to the shape of fried egg
- 28. type of nervous tissue, support neurons
- 30. group of fibers in connective tissue proper, long, unbranching, strong, flexible, and resistant to stretching
- 31. type of epithelial layer, single layer of cells with apical surfaces directly attached to basement membrane
- 32. cells that reside in lacunae, secrete gel-like extracellular matrix containing collagen and elastic fibers
- 34. loose connective tissue proper, contains reticular fibers; found in spleen, lymph nodes, and bone marrow
- 35. dense connective tissue proper, collagen fibers aligned parallel to applied force, found in tendons and ligaments
- 36. type of epithelial layer, single layer but not all cells reach apical surface and nuclei give multilayered, stratified appearance
- 38. cartilage supporting connective tissue, densely interwoven collagen fibers act as shock absorber, found in intervertebral disc, pubic symphysis, and the menisici of the knee
- 39. connective tissue proper that has more protein fibers and less ground substance
- 40. muscle attached to bones of skeleton or facial skin, cylindrical and long, multinucleated, striated, voluntary
- 41. characteristic of epithelial tissue, lacking blood vessels, cells receiving nutrients through diffusion from underlying tissues
- 42. muscle found in the walls of most internal organs, relatively short, wide in the middle, tapered at the ends (fusiform), involuntary, non-striated
- 43. connective tissue proper that has fewer protein fibers and more ground substance
- 44. muscle found in the wall of the heart (myocardium), branched, Y-shaped, shorter than skeletal fiber cells, striated, involuntary, attached to each other via strong gap junctions
- 45. group of connective tissue proper, move through connective tissue spaces, involved in immune functions
- 46. group of connective tissue proper, stationary, produces extracellular matrix, can store material, and can have immune function
- 47. perform secretory function producing mucin, hormones, enzymes, and waste products
Down
- 1. secondary portion of extracellular matrix besides protein fibers
- 3. tissues providing protection, connection, and support
- 5. group of fibers in connective tissue proper, thinner than collagen fibers, form meshwork-like configuration, found in organs with abundant spaces such as liver, lymph nodes, and spleen, acting as packing material
- 6. tissue aiding in movement and compression
- 7. bottom surface
- 9. tissue covering surfaces, lining inside of body cavities and organs
- 12. characteristic of epithelial tissue, containing nerve endings to detect changes in environment at a body or organ region
- 14. group of fibers in connective tissue proper, thinner than collagen, stretches easily, branch, and rejoin, allow structures like blood vessels to stretch and relax
- 15. gap junctions that allow rapid passage of electrical current from one cell to the next during each heart beat
- 18. shared membrane specializations that bind epithelial cells tightly together via lateral surfaces
- 19. loose connective tissue proper, "fat", comprised mainly of adipocytes (fat cells) and very little else
- 20. dense connective tissue, irregular arrangement of collagen fibers, found in deep portion of skin (dermis) around some organs
- 22. loose connective tissue proper, abundant ground substance, protects organs and tissues
- 24. characteristic of epithelial tissue, cells are damaged frequently or die, replacement occurring just as quickly
- 27. cells that make up bone
- 29. characteristic of epithelial tissue, basal surface is attached to basement
- 33. acellular structures produced by both epithelial and underlying connective tissue cells
- 37. top or exposed
