Final answer:
The Eccrine gland (A) is found all over the body, especially on the forehead, palms, and soles, and it plays a key role in thermoregulation and homeostasis.
Step-by-step explanation:
The type of sudoriferous gland that is found all over the body, primarily on the forehead, palms of the hands, and soles of the feet is the Eccrine gland (A). These glands are especially abundant in these areas and produce a hypotonic sweat that is important for thermoregulation. The Eccrine glands are coiled tubular glands that lie deep in the dermis with ducts extending to a pore on the skin surface. The sweat they release through exocytosis is mainly water, with some salt, antibodies, metabolic waste, and dermicidin, which is an antimicrobial peptide. The primary role of Eccrine sweat is to help maintain the body's homeostasis by regulating temperature.
