Explanation:

• Question 16: Lanugo is the fine - soft hair coat that covers the fetus around the sixth month of pregnancy. Papilla is related to structures like taste papillae, vellus is fine hair on adult skin, and sebum is an oily secretion.
• Question 17: The dermis has a thin papillary layer and a thick reticular layer. Epidermal is the outer layer of the skin, muscle is not part of the dermis layers, and connective tissue is a general term not specific to the dermis layer.
• Question 18: The three kinds of microscopic skin glands are sweat, sebaceous, and ceruminous glands. Eccrine is a type of sweat gland, so the combination with it and the other two is incorrect.

Answer:

Question 16: A. lanugo
Question 17: A. reticular
Question 18: B. sweat, sebaceous, and ceruminous
