Which hormone do sudoriferous glands secrete?

Sudoriferous glands, commonly known as sweat glands, are responsible for producing and secreting sweat, which plays a crucial role in regulating body temperature and maintaining homeostasis. Among the choices provided, the secretion of apocrine pheromones is the correct association with these glands.

Apocrine glands, a type of sudoriferous gland, are primarily found in specific areas such as the armpits and groin. These glands don't directly contribute to temperature regulation like the eccrine glands but instead secrete a thicker, milky substance that can contain proteins and fatty acids. This secretion is thought to play a role in olfactory communication or pheromone signaling between individuals, especially in attracting potential mates. Pheromones are chemical signals released by an individual that can affect the behavior of another individual of the same species.

In contrast, the other options like adrenaline, estrogen, and testosterone are hormones that play various roles in the body, but they are not secreted by sudoriferous glands. Adrenaline is related to the body's fight-or-flight response, while estrogen and testosterone are steroid hormones involved in reproductive functions and secondary sexual characteristics. Therefore, apocrine pheromones are distinct in that they directly relate to the secret
