Quizplus · Accepted Answer

Serous membranes secrete a fluid that acts as a lubricant to reduce friction between the parietal and visceral surfaces of internal cavities. Cutaneous and mucous membranes do not line internal cavities, and synovial membranes are found in joints, not internal cavities. The lamina propria is a component of mucous membranes.
