Across
  1. 3. acellular structures produced by both epithelial and underlying connective tissue cells
  2. 9. type of epithelial layer, single layer but not all cells reach apical surface and nuclei give multilayered, stratified appearance
  3. 12. group of cells performing similar functions
  4. 13. bottom surface
  5. 15. substance produced by cells of specific tissue containing protein fibers, salts, water, and dissolved macromolecules located outside of the cell
  6. 17. characteristic of epithelial tissue, cells having apical surface and basal surface where they attach to underlaying cells/tissues
  7. 18. top or exposed
  8. 19. characteristic of epithelial tissue, basal surface is attached to basement
  9. 21. same size on all sides, nucleus is centrally located
  10. 22. characteristic of epithelial tissue, composed almost entirely of cells with little extracellular matrix, bound together by intercellular junctions
  11. 23. type of epithelial layer, single layer of cells with apical surfaces directly attached to basement membrane
Down
  1. 1. characteristic of epithelial tissue, cells are damaged frequently or die, replacement occurring just as quickly
  2. 2. shared membrane specializations that bind epithelial cells tightly together via lateral surfaces
  3. 4. perform secretory function producing mucin, hormones, enzymes, and waste products
  4. 5. tissue aiding in movement and compression
  5. 6. characteristic of epithelial tissue, lacking blood vessels, cells receiving nutrients through diffusion from underlying tissues
  6. 7. type of epithelial layer, two or more layers of cells that don't all have apical surfaces or are attached to basement membrane
  7. 8. tissue covering surfaces, lining inside of body cavities and organs
  8. 10. tissues providing protection, connection, and support
  9. 11. characteristic of epithelial tissue, containing nerve endings to detect changes in environment at a body or organ region
  10. 14. flattened, similar to the shape of fried egg
  11. 16. taller than wide, nucleus is oval and located in basal region of cell
  12. 20. tissue that operates communication
