Question

in contrast to serous or mucous membranes, the cutaneous membrane ________. answer options: is thick, relatively waterproof, and usually dry; is thin, permeable to water, and usually moist; has a specialized connective tissue, the lamina propria; is lubricated by goblet cells found in the epithelium; i dont know yet

Explanation:

To solve this, we analyze the properties of the cutaneous membrane (skin) vs serous/mucous membranes:

• Serous membranes are thin, moist, and line body cavities. Mucous membranes line cavities open to the outside (like respiratory, digestive) and are moist, with goblet cells (for mucus) and lamina propria (connective tissue).
• The cutaneous membrane (skin) is thick, waterproof (due to keratin), and usually dry.
• Option 2 is incorrect (skin is not thin, permeable, or moist).
• Option 3: Lamina propria is in mucous membranes, not cutaneous.
• Option 4: Goblet cells are in mucous membranes, not cutaneous.

So the correct description is the first option.

Answer:

A. is thick, relatively waterproof, and usually dry
