{{Main|Endocrine gland}}
Endocrine glands are [[gland]]s of the endocrine system that secrete their products, [[hormone]]s, directly into interstitial spaces where they are absorbed into blood rather than through a duct. The major glands of the endocrine system include the [[pineal gland]], [[pituitary gland]], [[pancreas]], [[Ovary|ovaries]], [[Testicle|testes]], [[thyroid|thyroid gland]], [[parathyroid gland]], [[hypothalamus]] and [[adrenal gland]]s. The hypothalamus and pituitary gland are [[neuroendocrine]] [[Organ (anatomy)|organ]]s.

The hypothalamus and the anterior pituitary are two out of the three endocrine glands that are important in cell signaling. They are both part of the HPA axis which is known to play a role in cell signaling in the nervous system.

Hypothalamus: The hypothalamus is a key regulator of the autonomic nervous system. The endocrine system has three sets of endocrine outputs<ref>{{cite journal |author1=Clifford B.

The magnocellular is involved in the expression of oxytocin or vasopressin. The [[Parvocellular neurosecretory cell|parvocellular]] is involved in controlling the secretion of hormones from the anterior pituitary.

[[Anterior pituitary|Anterior Pituitary]]: The main role of the anterior pituitary gland is to produce and secrete [[tropic hormone]]s.<ref>{{cite book |url=https://accessmedicine.mhmedical.com/content.aspx?bookid=507&sectionid=42540503 |title=Endocrine Physiology |publisher=McGraw Hill |year=2013 |editor-link=Patricia E.
