Which gland is responsible for producing sweat for thermoregulation?

• A. Apocrine gland
• B. Sebaceous gland
• C. Eccrine gland
• D. Ceruminous gland

Answer: (C)

The eccrine gland plays a vital role in thermoregulation through the production of sweat. This type of gland is distributed widely across the human body, especially on the palms, soles, and forehead. When the body temperature rises due to environmental heat or physical activity, the eccrine glands secrete a watery, clear fluid that evaporates from the skin surface, facilitating cooling. This process is essential for maintaining homeostasis, as it helps to prevent overheating by regulating body temperature. In contrast, apocrine glands, which are located primarily in the axillary and genital regions, are associated with scent production rather than thermoregulation. Sebaceous glands are responsible for oil production to lubricate and protect the skin, while ceruminous glands produce earwax for the protection of the ear canal. None of these glands contribute to the primary function of sweat production as it relates to thermoregulation like the eccrine glands do.
