Describe eccrine glands' structure and how the sweat is produced.

Answer (Click to Show Hidden Text)

Structure: Consists of a secretory unit that consists of a secretory coil rolled into a glomerulum. The secretory layer is deep in the dermis and hypodermis and is surrounded by adipose tissue. Sweat is produced by sweat glands. (I'm not really sure what you meant.)

What I meant by sweat is produced (Click to Show Hidden Text)

Glycogen-rich secretory cells make isotonic sweat, dark mucoidal cells reabsorb NaCl, making the sweat hypotonic. Myoepithelial cells triggered by cholinergic fibers squeeze the sweat onto the skin surface.
