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