With a relevant example, describe and illustrate the organisation of neuroendocrine control, and explain its significance.
Neuroendocrine system is basically made up of neuroendocrine
cells .Neuroendocrine cells comprises of nerve cells known as
neurons and endocrine cells which is involved in regulating
hormones release by receiving the signals from nerve cells
.Ultimately hormones act on different parts of the body .
Example of neuroendocrine integration is Of Hypothalamus pituitary
adrenal axis .
Normally Hypothalmus produces trophic hormones factors (
Thyrotropin releasing hormone TRH,CRH corticotropin releasing
hotmone )which will go and act on pituitary glands and it will
release various hormones like ( Thyroid stimulating hormone ,
Adrnocorticotropic hormones ) which will finally act on respective
glands like Thyroid ,adrenal medulla to release thyroid hormones
,and adrenaline in blood which will exerts its further actions .So
any abnormality in hypothalmus it will not release the trophic
hormones and no Further release from pituitary and target organs
and no further actions on various parts of the body .
So in absence of TSH pateint may develop hypothyroidism freatures (
Cold intolerance ,lethargy ) and no release of adrenaline will not
allow the body to cope up with stress .Hence in this way
neuroendocrine system is integrated and work hand in hand .
