What is lanugo or vellus hair an appendage of?

Dermal layer
Sebaceous gland
Epidermis
Follicle

The correct answer is: Sebaceous gland

Lanugo, also known as vellus hair, is primarily an appendage of the follicle. This type of hair is fine and soft, typically found on the body of a fetus and sometimes in adults in areas like the face, neck, and arms. The follicle is the structure from which hair grows, encompassing the hair root and associated structures. Choosing the follicle as the correct answer highlights the biological connection between hair growth and the skin's anatomy. The follicle is crucial for hair development, as it contains the cells that proliferate to form the hair shaft. Understanding this relationship underscores the importance of the follicle in hair type and distribution on the body.
