According to Henry Gray's estimates, the palm has around 370 sweat glands per cm 2; the back of the hand has 200 per cm 2; the forehead has 175 per cm 2; the breast, abdomen, and forearm have 155 per cm 2; and the back and legs have 60–80 per cm 2. [2] In the finger pads, sweat glands pores are somewhat irregularly spaced on the epidermal ridges.
