Hormones of the Anterior Pituitary

Hypothalamus produces 2 types of endocrine factors

1. Hypothalamic neuropeptides
2. Hypothalamic releasing factors

• The releasing factors are neurosecretions synthesized in the hypothalamus and released through the hypothalamic pituitary portal circulation. 
• They have their effect on the secretion of pituitary tropic hormones.
• Secretion of hormones by Adenohypophysis (Anterior Pituitary), is under control of peptides secreted by hypothalamus. 
• These can be stimulants or inhibitors. 
• Their secretion is also under the feedback control of anterior pituitary tropic hormones – short loop feedback as well as target glands hormones (long feedback loop).

  * “A tropin or tropic hormone is the one which influences the activities of other endocrine glands”

• Principally those involved in stress and reproduction. 
• These are carried by the blood to other target gland. 
• The pituitary tropins are under the positive & negative control of peptide factors from hypothalamus.

All these lectures are organized and listed in detail in their proper sections. To view these lessons please visit the Hormones and Signal Transduction Section in Biochemistry II.
This can be approached by directly clicking the Biochemistry II button or it can also be approached from the drop down menu in Biochemistry II tab. Once you reach the section click the curriculum tab to view the full list in the section.

Any further questions or inquiries are welcome.

NOTE: Private coaching / tutoring services are also available. Students can also get these online.
