What type of glands are oil glands located in the dermis that are found all over the body except the palms and soles?

Sebaceous glands are specialized structures located within the dermis of the skin, responsible for producing sebum, an oily substance that helps to lubricate and protect the skin and hair. These glands are present all over the body except for the palms of the hands and the soles of the feet; this distribution is significant as it correlates with the function of sebum in preventing dryness and providing a barrier against environmental factors.

The secretion from sebaceous glands plays a crucial role in maintaining skin hydration and providing antibacterial properties, which is vital for skin health. Unlike sweat glands, which primarily assist in thermoregulation through perspiration, sebaceous glands focus on moisturizing the skin. This distinction highlights the different functions that various gland types serve within the integumentary system.

Therefore, the choice of sebaceous glands as the correct answer effectively captures the specific function and distribution of these oil-producing glands within the body's skin system, underscoring their importance in maintaining skin integrity and health.
