hands
The forehead has a higher density of sweat glands compared to the forearm. This is because the forehead is an area of the body that is more prone to overheating and requires more efficient cooling through sweat production.
scalp
The palms have more sweat glands. It contains about 600 glands per cm2
Sweat glands are found in almost every part of the skin, forming tiny coiled tubes embedded in the dermis or subcutaneous fat. There are two types of sweat gland: eccrine glands and apocrine glands.
The most common kind of sweat glands found in humans are eccrine sweat glands. These glands are distributed throughout the body and produce a watery sweat that helps regulate body temperature. Apocrine sweat glands are another type, but they are found primarily in the armpits and groin area and produce a thicker, odorless secretion.
There are a large number of medical conditions that lead to decreased sweating, either in one area or all over the body. http://www.allaboutsweat.com/decreasedsweating.html provides a good overview.
There are two types of sweat glands on the skin: apocrine â?? found mainly in the armpit area â?? and eccrine glands, which are found all over the skin surface. The mechanism of sweating, is controlled by the bodyâ??s autonomic nervous system
Apocrine glands are larger sweat glands found in the axillae (armpits) and around the genital area. They produce a thicker secretion that can be affected by emotional stress and hormonal changes, leading to body odor.

Maintenence of a stable body temperature requires that the amount of body heat lost is balanced by the amount produced. Heat is a product of cellular metabolism; thus, the more active cells of the body are the major heat producers. These cells include the skeletal and cardiac muscles cells and the cells of certain glands, such as the liver. As the body temperature rises, nerve impulses stimulate structures in the skin and other organs to release heat.
