Question

Pheromones are secreted by

• A. Endocrine gland
• B. Exocrine gland
• C. Apocrine gland
• D. Mixed gland

Answer 1

Answer: (C)

Apocrine gland

In humans, pheromones are secreted onto our skin through the apocrine glands (sometimes called as human scent glands). These are similar to eccrine glands but the apocrine glands secrete a more oily substance. The apocrine glands are normally associated with hairy areas, such as armpits and the crotch area, and are also usually accompanied by eccrine glands, which help to disperse the pheromone secretions. Apocrine glands are activated at puberty, along with hair growth in the axillary (armpit) regions and crotch, which increase the surface area for pheromone dispersal.
