The production of some hormones is
controlled by positive feedback
In
such a system, hormones cause a condition to intensify, rather than decrease.
As the condition intensifies, hormone production increases.
Such
positive feedback is uncommon, but
does occur during childbirth, where hormone levels build with increasingly
intense labor contractions. Also
in lactation, hormone levels increase in response to nursing, which causes an
increase in milk production. The
hormone produced by the hypothalamus causing the milk let down and uterine
contraction is oxytocin.
Unlike exocrine and endocrine glands
Exocrine Glands are those roomates release their cellular secretions through a duct roomates empties to the outside or into the lumen (empty internal space) of an organ. These include certain sweat glands, salivary and pancreatic glands, and mammary glands. They are not Considered a part of the endocrine system.
Endocrine Glands are those glands roomates have no duct and release their secretions directly into the intercellular fluid or into the blood. The collection of endocrine glands makes up the endocrine system.
