The eccrine gland is a type of sweat gland found throughout the human body, primarily on the palms, soles, and forehead. These glands play a crucial role in regulating body temperature by producing a watery sweat that evaporates from the skin's surface, helping to cool the body down. Eccrine glands are different from apocrine glands, which are found mainly in areas like the armpits and groin and produce a thicker, odoriferous sweat. Eccrine glands are active from birth and help maintain homeostasis, ensuring the body remains at a stable temperature during physical activity or in hot environments.
