Sebaceous glands in the dermis empty their secretion into which structure, and what is the secretion called?
Explanation
Sebaceous glands are holocrine glands attached to nearly every hair follicle on the body except the palms and soles. They release sebum, an oily lipid mixture (triglycerides, wax esters, squalene) made by the breakdown of the gland's own cells, into the upper portion of the hair follicle. Sebum then travels up the follicular canal and lubricates the hair and skin surface. Recognizing the anatomy supports safe extraction technique and product selection, both within the scope of California licensees under Bus. & Prof. Code §7320. Option B confuses sebaceous with sudoriferous (sweat) glands. Option C names an unrelated cellular mediator. Option D confuses sebum with collagen, a structural fiber made by fibroblasts.
