Question

The epidermis of mammals is characterized by the absence of

• A. Mucous glands
• B. Femoral pores
• C. Poison glands
• D. All of the above

Answer 1

Answer: (D)

All of the above

Femoral pores are a part of a holocrine secretory gland found on the inner side of the thighs of certain lizards and amphibians, which release pheromones to attract mates. Poison glands are specialized glands in certain fishes and amphibians, which secrete poisonous mucus-like substances. The mucous salivary glands are similar in structure to the buccal and labial glands. They are found especially in the back part of the vallate papillae in humans.

So, the correct answer is 'All of the above'
