Question

The hypothalamus does not play a role in controlling blood glucose levels.  True  False

Answer 1

Hypothalamus is present just below the thalamus in the brain which controls the pituitary gland which is the master gland.

According to the article published in nature the findings suggest that hypothalamus play an important role in maintaining blood glucose levels. We know that hormones released by pancreas example insulin maintain stable levels of glucose in the blood. A region of brain called ventromedial hypothalamus is responsible for regulating blood glucose. This was first discovered by Friedman. we know that brain senses the low glucose levels and helps to maintain stable levels. It was now well clear that a group of hypothalamic neurones sense glucose levels and affect the secretion of anti insulin hormones.

The hypothalamus is the control centre of brain which states in proper functioning of pancreas. Is hypothalamus is not functioning properly or it is signalling is disturbed then there will be no regulation of homeostatic blood glucose.

So it can be said that hypothalamic stimulation results in increased blood glucose levels. Inferior cases there will be direct stimulation of glucagon secretion and indirect inhibition of insulin.

So as per the recent studies secretion of insulin and other islet hormones are influenced by hypothalamus and other brain areas and insulin action in the hypothalamus influences both energy balance and glucose metabolism.

So answer is B false.
