Across
  1. 2. A body tissue that contracts or shortens, making body parts move.
  2. 4. Glands that secrete substances outward through a duct to the epithelial surface; ex) sweat and oil glands
  3. 7. Connective tissue made of plasma, erythrocytes, leukocytes, and platelets.
  4. 9. Involuntary muscle found inside many internal organs of the body
  5. 12. an epithelial tissue that secretes mucus and that lines many body cavities and tubular organs including the gut and respiratory passages; also called mucosa
  6. 14. Ductless glands that secrete hormones directly into the bloodstream; ex) thyroid and pituitary glands
  7. 15. Thin layer of tissue that covers internal body cavities and secretes a fluid that keeps the membrane moist; also called serosa
  8. 17. The bottom surface of epithelial tissue that attaches to the basement membrane
  9. 19. An upper free surface exposed to the body exterior or the cavity of an internal organ
  10. 21. A nerve cell
  11. 23. Connective tissue that contains reticular fibers and cells; used to make the framework of major organs
  12. 24. A body tissue that provides support for the body and connects all of its parts
  13. 25. A muscle that is attached to the bones of the skeleton and provides the force that moves the bones.
  14. 26. Connect muscle to bone
  15. 27. cube-shaped cells, as tall as they are wide
  16. 30. The chemical substances located between connective tissue cells
Down
  1. 1. Flat cells; structure is ideal for diffusion/transport
  2. 3. collection of fat cells
  3. 4. A body tissue that covers the surfaces of the body, inside and out
  4. 5. Layer between epithelium and underlying connective tissue
  5. 6. Connect bone to bone
  6. 8. Connective Tissue that wraps and cushions organs and is widely distributed under epithelia of body
  7. 10. Groups of cells with a common structure and function.
  8. 11. A connective tissue that protects the ends of bones and keeps them from rubbing together.
  9. 13. Connective Tissue made mostly of collagen fibers; forms strong, ropelike structures like tendons and ligaments
  10. 16. A body tissue that carries electrical messages back and forth between the brain and every other part of the body.
  11. 18. Multiple layers
  12. 20. Connective Tissue surrounds various organs and supports both nerve cells and blood vessels; may be areolar, adipose or reticular
  13. 22. Dense, hard connective tissue composing the skeleton
  14. 27. column-shaped cells, taller than they are wide; ideal for secretions
  15. 28. The muscle tissue of the heart
  16. 29. cells that support and protect neurons
