The apocrine sweat glands, usually associated with hair follicles, continuously secrete fatty sweat into the glandular ducts. Emotional stress causes the tubular walls to contract, excreting fat secretions into the skin, where local bacteria break them down into odorous fatty acids.
What is the function of apocrine secretion?
A type of gland found in the skin, breasts, eyelids, and ears. The apocrine glands of the breast secrete lipid droplets into the milk, and the apocrine glands of the ear help form earwax. The apocrine glands of the skin and eyelids are sweat glands.
What does the sweat glands excrete?
Sweat glands are used to regulate temperature and remove waste products by secreting water, sodium salts, and nitrogen waste (such as urea) on the surface of the skin. The main electrolytes of sweat are sodium and chloride, but the amount is sufficient to make the sweat hypotonic on the surface of the skin.
How do apocrine glands release their products?
A distinct feature of apocrine glands is that they secrete their products by hair loss, which is associated with apical cytoplasmic membrane germination.
Where are the apocrine sweat glands emptied?
Glandular ducts are emptied into adjacent hair follicles. The vesicles on the apical surface of the secreting cells suggested that the cells received apocrine secretion, but recent electron micrographs show that the cells use melocrine secretion.
