What type of sweat gland is responsible for temperature regulation?

Eccrine glands play a vital role in temperature regulation through the process of sweating. These glands are distributed widely across the body, especially on the palms of the hands, soles of the feet, and the forehead. When body temperature rises, whether due to heat, exercise, or stress, eccrine glands secrete a watery, salt-rich sweat onto the surface of the skin.

As this sweat evaporates, it cools the skin and helps to lower the body's core temperature. This mechanism of thermoregulation is crucial for maintaining homeostasis, especially in hot environments or during physical exertion.

The other types of glands mentioned have different functions and are not primarily involved in temperature regulation. For instance, apocrine glands are located mainly in the armpits and groin and become active during puberty, primarily producing a thicker secretion in response to emotional stress rather than temperature changes. Ceruminous glands produce earwax, serving as a protective barrier in the ear canal. Sebaceous glands secrete sebum, which helps lubricate and protect the skin and hair but does not directly contribute to thermoregulation.
