Eccrine glands (/ˈɛkrən/, /ˈɛˌkrn/, or /ˈɛˌkrin/; from ekkrinein "secrete";[3] sometimes called merocrine glands) are the major sweat glands of the human body, found in virtually all skin.[4] 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 sweat glands). NaCl is reabsorbed in the duct to reduce salt loss.[5] They are active in thermoregulation and emotional sweating (induced by anxiety, fear, stress, and pain).[6]:170

Eccrine glands are composed of an intreaepidermal spiral duct, the "acrosyringium"; a dermal duct, comprising a straight and coiled portion; and a secretory tubule, coiled deep in the dermis or hypodermis.[6]:172 Eccrine glands are innervated by the sympathetic nervous system, primarily by cholinergic fibers, but by adrenergic fibers as well.[7]

Dermcidin is a newly isolated antimicrobial peptide produced by the eccrine sweat glands.[8]
