Which glands are involved in the secretion of sebum?

1. Follicular glands

2. Sudoriferous glands

3. Sebaceous glands

4. Dermal glands

The correct answer is: Sebaceous glands

Sebaceous glands are the primary glands responsible for the secretion of sebum, an oily substance that helps to lubricate and protect the skin and hair. These glands are typically associated with hair follicles and play a crucial role in maintaining skin hydration and providing a barrier against environmental factors. Sebum production is essential for the health of the skin, as it helps to prevent dryness and can also have antimicrobial properties that protect the skin from pathogens. The activity of these glands is influenced by factors such as hormones, particularly androgens, which can increase sebum production, especially during puberty. While the other glands listed may have their own important functions in the skin, they do not directly contribute to sebum secretion. Follicular glands and dermal glands are not classifications that pertain to sebum production. Sudoriferous glands, or sweat glands, primarily aid in thermoregulation and excretion, secreting sweat rather than sebum. Understanding these distinctions is important for estheticians as they assess and treat various skin types and conditions.
