Show answer & explanationAnswer & explanation
Correct answer: A. Sebaceous gland
Sebaceous glands are exocrine glands in the skin that produce sebum, an oily substance. Overactivity of these glands leads to oily skin.
Why the other options are wrong
- B. Melanocytes produce melanin, the pigment that determines skin color.
- C. Eccrine glands produce watery sweat for thermoregulation.
- D. Apocrine glands produce a thicker sweat, primarily in axillary and genital areas, associated with body odor.
Sebaceous Glands
Sebaceous glands are small exocrine glands in the skin that secrete an oily, waxy substance called sebum.
- Typically associated with hair follicles.
- Secrete sebum to lubricate and waterproof the skin and hair.
- Sebum also has antibacterial properties.
- Overactivity can lead to oily skin and acne.
Memory trick: Sebaceous glands secrete 'sebum' (like 'sebum' is 'greasy').
