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