What is the most widely distributed type of sweat gland?

The eccrine sweat gland is the most widely distributed type of sweat gland. They are found in the skin throughout the body’s surface and are important in thermoregulation. Apocrine glands are sweat glands primarily located in the groin and armpits. Sweat glands are exocrine glands, not endocrine glands. Submucosal glands are those that secrete mucus, not sweat.
