Across
- 3. consists of two or more layers of cells
- 9. localized spot-like adhesions randomly arranged on the lateral sides of plasma membranes
- 13. a microscopic finger-like projection that increases the surface area of cells
- 15. "appears" to have several layers; may secrete mucus; may have cilia
- 17. single row of cube-like cells; functions in secretion and absorption; found in thyroid gland and kidneys
- 18. arranged like thin floor tiles with a pancake-shaped nucleus
- 19. cell surface that faces the body surface, cavity, lumen, or duct
Down
- 1. specialized intercellular connection which directly connect the cytoplasm of two cells, allowing ions and electrical impulses to move directly between cells
- 2. cube-like cells that have a round centrally located nucleus; function in secretion and absorption
- 3. single layer of cells that function in diffusion, filtration, secretion, and absorption
- 4. unicellular exocrine gland; secretes mucus
- 5. thin, fibrous, extracellular matrix of tissue that separates the lining of an internal or external body surface from underlying connective tissue
- 6. secretions enter the intersitial fluid and blood stream without using ducts
- 7. multiple layers of cube-like cells with a central nucleus
- 8. opposite of apical
- 10. multiple layers that are flat at the apical surface and cube or column-like at the basal surface; may be keratinized or nonkeratinized
- 11. glands that use ducts to transfer secretions
- 12. one layer of flat pancake-like cells found where filtration and diffusion occurs such as the alveoli
- 14. single row of rectangular shaped cells with a nucleus near the base; may be ciliated; functions in secretion and absorption
- 16. cells much taller than they are wide; apical surface may have cilia or villi; function in secretion and absorption
