Explanation:

Analyze sebum function

Using the Integumentary System Layers knowledge point, sebum is an oily secretion produced by sebaceous glands. It lubricates the skin and hair, prevents water loss (dehydration), and contains antimicrobial lipids that inhibit bacterial growth.

Determine the thickest skin layer

Using the Integumentary System Layers knowledge point, the skin (cutis) consists of the epidermis and the dermis. The dermis is a dense connective tissue layer that is significantly thicker than the epithelial epidermis. The hypodermis (subcutaneous layer) lies beneath the skin.

Identify hypodermis synonyms

Using the Dermatological Terminology knowledge point, the hypodermis is the lowermost layer of the integumentary system, located directly below the dermis. It is commonly referred to as the subcutis or subcutaneous tissue.
