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