A sectional view of the skin (magnified). Sweat gland labeled as "sudoriferous gland" at center right. This is the most common sweat gland in the body.

Eccrine glands (or merocrine glands) are the major sweat glands of the human body, found in virtually all skin.[1]. They produce a clear, odorless substance, consisting primarily of water and NaCl (note that the odor from sweat is due to bacterial activity on the secretions of the apocrine glands). NaCl is reabsorbed in the duct to reduce salt loss [2]. They are active in thermoregulation[3], which is controlled by the hypothalamus.

Eccrine glands are composed of (1) an intreaepidermal spiral duct, the "acrosyringium," (2) a straight dermal portion, and (3) a coiled acinar (grape-like) portion in the dermis or hypodermis. Innervation is by the sympathetic nervous system (primarily by cholinergic fibers, but also by adrenergic fibers[4]).
