Structure
The apocrine gland comprises a glomerulus of secretory tubules and an excretory duct that opens into hair follicle; on occasion, an excretory duct opens to the skin surface next to the hair. The gland is large and spongy, located in the subcutaneous fat deep in the dermis, and has a larger overall structure and lumen diameter than the eccrine sweat gland. Unlike eccrine secretory tubules, secretory tubules of the apocrine gland are single-layered (lacking ductal cells), vary in diameter from place to place, and sometimes branch off into multiple ducts. The tubules are wrapped in myoepithelial cells, which are more developed than their eccrine gland counterparts.

Famous quotes containing the word structure:
“What is the most rigorous law of our being? Growth. No smallest atom of our moral, mental, or physical structure can stand still a year. It grows—it must grow; nothing can prevent it.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“A structure becomes architectural, and not sculptural, when its elements no longer have their justification in nature.”
—Guillaume Apollinaire (1880–1918)
“Agnosticism is a perfectly respectable and tenable philosophical position; it is not dogmatic and makes no pronouncements about the ultimate truths of the universe. It remains open to evidence and persuasion; lacking faith, it nevertheless does not deride faith. Atheism, on the other hand, is as unyielding and dogmatic about religious belief as true believers are about heathens. It tries to use reason to demolish a structure that is not built upon reason.”
—Sydney J. Harris (1917–1986)
