Which glands are located everywhere on the body except the palms of hands and soles of feet?

• A. Sweat glands
• B. Sebaceous glands
• C. Endocrine glands
• D. Exocrine glands

Answer: (B)

Sebaceous glands are the correct answer as they are distributed throughout the skin, except on the palms of the hands and the soles of the feet. These glands are responsible for producing sebum, an oily substance that helps to lubricate the skin and hair, providing a barrier against water loss and protecting the skin from pathogens. The absence of sebaceous glands in areas like the palms and soles is thought to be due to the different needs for protection and moisture in these regions, which are more prone to abrasion and require a tougher outer layer of skin. In contrast, sweat glands, which are involved in thermoregulation and are found all over the body including the palms and soles, serve a different function. Endocrine glands, which release hormones directly into the bloodstream, and exocrine glands, which secrete substances through ducts, do not pertain specifically to the skin's surface in the same way that sebaceous glands do. Therefore, sebaceous glands' distribution pattern aligns perfectly with the question, making it the correct choice.
