Question: 1 / 400

What is the primary function of sebaceous glands?

Produce sweat for thermoregulation

Secrete an oily substance called sebum

Sebaceous glands are specialized exocrine glands that primarily secrete an oily substance known as sebum. Sebum plays a crucial role in maintaining skin health by providing lubrication, preventing the skin and hair from becoming dry and brittle. Additionally, sebum has antimicrobial properties that help protect the skin from harmful microorganisms, contributing to overall skin integrity.

The main purpose of sebum production is to maintain the skin's barrier function and to aid in keeping the hair soft and pliable. The secretion of sebum is typically stimulated by hormones, particularly androgens, which is why sebaceous gland activity often increases during puberty. This aspect highlights the glands' significance in skin physiology and maintenance rather than in other functions like thermoregulation, hormonal secretion, or nutrient absorption, which are handled by different systems in the body.
