In which gland do secretions primarily respond to hormonal control rather than temperature changes?

The apocrine gland is primarily associated with hormonal control rather than temperature regulation. Apocrine glands, found in areas like the armpits and groin, become active during puberty and are stimulated by hormones, particularly those associated with stress or sexual arousal. Their secretions contain proteins and fatty substances that lead to the characteristic odor when they are broken down by bacteria on the skin.

In contrast, eccrine glands are mainly involved in thermoregulation through the secretion of sweat, which helps cool the body. The thyroid and parathyroid glands, while also hormonal in nature, do not fit the context of glandular secretions linked to external stimuli or pheromonal responses, as they primarily manage metabolic processes and calcium levels respectively. Therefore, the apocrine gland's responsiveness to hormonal changes is what makes it the correct choice in the context of the question.
