Answer to Question #76412 in Biochemistry for AAya

Question #76412
Outline how the hypothalamus regulates the concentration of hormones in the blood.
Expert's answer
Hypothalamus has specific cells that can detect the presence of big molecules such as hormones in the blood. The vessels here are also specific and can permit large molecules like hormones to leak into the tissues and carry signals to the neurons. Hypothalamus neurons also receive impulses from other neurons by electrical signals.
When the hypothalamus, establishes a need for the response, hypothalamic cells influence the other cells by production peptide hormones like oxytocin or ADH.
The second way of influence is the production of peptides that increase or decrease the production of other eight specific hormones to the bloodstream. The regulation is provided by negative feedback.
