[[File:Gray946.png|thumb|Body of a sweat gland cut in various directions]]
Generally, sweat glands consist of a ''secretory unit'' consistingthat ofproduces a base rolled into a [[wikt:glomerulus|glomerulum]]sweat, and a ''duct ''that carries the sweat away.<ref name=randall46 /> The ''secretory coil ''or base, is set deep in the lower [[dermis]] and [[hypodermis]], and the entire gland is surrounded by [[adipose tissue]].<ref name=grayanat /><ref name=caceci />{{sfn|Kurosumi|Shibasaki|Ito|1984|p=255}} In both sweat gland types, the secretory coils are surrounded by contractile myoepithelial cells that function to facilitate excretion of secretory product.{{sfn|Kurosumi|Shibasaki|Ito|1984|p = 256}}{{sfn|Eroschenko|2008|pp = 222, 226, 228}} The secretory activities of the gland cells and the contractions of [[myoepithelial cells]] are controlled by both the autonomic nervous system and by the circulating hormones. The distal or apical part of the duct that opens to the skin's surface is known as the ''acrosyringium''.<ref name="Bolognia et al">{{Cite book|title = Dermatology.

Each sweat gland receives several [[nerve fibers]] that branch out into bands of one or more [[axons]] and encircle the individual tubules of the secretory coil. [[Capillaries]] are also interwoven among sweat tubules.<ref name="kennedy94" />
