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