e. movement of mucous 18. Whi c. cell j e, all of the above are characteristics 19. Glands that secrete their products directly into interstitial fuid rather than through ducts are classified as d. ceruminous e apocrine 20. A type of cell junction that prevents fluid from leaking into intercellular spaces is a a. spot desmosome b. gap junction c. tight junction e. lamina densa 21. Glands composed of cells that release their secretory products by cell lysis are a. merocrine b. holocrine c. apocrine d. pinocytotic e. phagocytic 22. The cell junction that allows adjacent cells to instantly exchange small molecules and ions is: b. a gap junction c. a tight junction d. a hemidesmosome e. all of the aboveExplanation / Answer
17. Desmosomes and hemidesmosomes are necessary for which tissue function:
(b) cell to cell communication.
These are the major cell surface attachment sites for the intermediate filaments.
18. Which of the following is not a characteristic of epithelial tissue:
(e) all of the above are characteristics.
19. Glands that secrete their products directly into interstitial fluid rather than through ducts are classified as
(a) endocrine.
Endocrine glands secrete hormones directly into the interstitial fluid.
20. A type of cell junction that prevents fluid from leaking into intercellular spaces is:
(c) tight junctions.
Tight junctions inhibit the passage of substances between cells and prevent organs from leaking into blood.
21. Glands composed of cells that release their secretory products by cell lysis are:
(b) holocrine.
22. The cell junction that allows adjacent cells to instantly exchange small molecules and ions is:
(b) gap junctions.
Gap junctions provide strength to the cells involved and allow the movement of small molecules and ions from the cell.
