Across
  1. 2. 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
  2. 4. muscle attached to bones of skeleton or facial skin, cylindrical and long, multinucleated, striated, voluntary
  3. 8. loose connective tissue proper, abundant ground substance, protects organs and tissues
  4. 12. gap junctions that allow rapid passage of electrical current from one cell to the next during each heart beat
  5. 18. group of connective tissue proper, stationary, produces extracellular matrix, can store material, and can have immune function
  6. 19. loose connective tissue proper, "fat", comprised mainly of adipocytes (fat cells) and very little else
  7. 21. type of nervous tissue, capable of initiating and conducting electrical activity throughout the body
  8. 22. muscle found in the walls of most internal organs, relatively short, wide in the middle, tapered at the ends (fusiform), involuntary, non-striated
  9. 24. dense connective tissue proper, collagen fibers aligned parallel to applied force, found in tendons and ligaments
Down
  1. 1. composed of cells called fibers
  2. 3. dense connective tissue, irregular arrangement of collagen fibers, found in deep portion of skin (dermis) around some organs
  3. 5. group of connective tissue proper, move through connective tissue spaces, involved in immune functions
  4. 6. cartilage supporting connective tissue, densely interwoven collagen fibers act as shock absorber, found in intervertebral disc, pubic symphysis, and the menisici of the knee
  5. 7. secondary portion of extracellular matrix besides protein fibers
  6. 9. cells that make up bone
  7. 10. cartilage supporting connective tissue, most common, found at ends of bones that articulate with each other, in trachea, larynx, and nose
  8. 11. cells that reside in lacunae, secrete gel-like extracellular matrix containing collagen and elastic fibers
  9. 13. group of fibers in connective tissue proper, long, unbranching, strong, flexible, and resistant to stretching
  10. 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
  11. 15. fluid connective tissue, comprised of plasma, erythrocytes, leukocytes, and platelets
  12. 16. 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
  13. 17. type of nervous tissue, support neurons
  14. 20. connective tissue proper that has fewer protein fibers and more ground substance
  15. 23. connective tissue proper that has more protein fibers and less ground substance
