Bio crossword Ch. 11

2. supports and connects body parts
4. multilayered cells, providing protection as in the skin
9. Non-cellular layer directly beneath the epithelial layer composed of proteins, provides natural structural support to overlying cells
11. Provides strength and elasticity
12. Fibroblasts, macrophages, lymphocytes, and neutrophils
13. Strong slightly flexible fibers
15. Stimulus not strong enough, will not generate sensation
16. Tight junctions sealing the plasma membranes together, digestive tract is an example.
18. Thinner, stretchy fibers
20. “Positively” charged, closer to zero
21. Cube shaped cells, form the lining of the kidney tubules; glandular tissues, etc

1. Potential for generating/sending signal
3. Period when an action potential cannot be generated, ONE SIGNAL AT A TIME!!
5. Considered the domino effect, action potential moves like a wave through the axon generating(consisting of a constant speed and amplitude)
6. Column shaped, Tall and rectangular. Lining the digestive tract, certain reproductive organs, as well as the layrnx
7. Permits some movement between cells, also allowing tissues to stretch and bend(ex, skin)
8. Flattened,forms outer surface of skin, lines blood vessels, Lungs, mouth, throat, etc
10. Thin inter-connective fibers of collogen, providing structure framework for soft organs(liver, spleen, lymph nodes)
14. Negatively charged, more unstable and further from zero
17. Consists of protein channels enabling movement of the materials between adjacent cells(communication)
19. single layer, adapted for diffusion across cells barriers, glands respiratory, digestive and reproductive systems
