Question

Quizplus · Accepted Answer

Goblet cells are specialized unicellular glands found in columnar and pseudostratified columnar epithelium. They secrete mucus, which lubricates and protects the surfaces they cover. Choice A (cilia) is incorrect because cilia refer to hair-like structures that help with movement, while goblet cells secrete mucus. Choice B (keratin) is incorrect because keratin is a protein found in the skin, hair, and nails that provides protection and waterproofing. Choice C (transitional cells) is incorrect because transitional cells refer to a type of epithelial cell found in the urinary system that is able to stretch and distend.
