give the relationship of hypothalamus and anterior lobe of the pitiutary gland?


Answer:
The anterior pituitary (also called the adenohypophysis, from Greek adeno, "gland"; hypo, "under"; physis, "growth"; hence, glandular undergrowth) comprises the anterior lobe of the pituitary gland and is part of the endocrine system. Unlike the posterior lobe, the anterior lobe is genuinely glandular, hence the root adeno in its name.Under the influence of the hypothalamus, the anterior pituitary produces and secretes several peptide hormones that regulate many physiological processes including stress, growth, and reproduction.
the hypothalamus helps regulate temperature and blood pressure...but the anterior lobe of the pituitary? never heard of it
The "Reader's Digest" version for a concept is that the hypothalamus sends messages downstream to the pituitary which does the same to the adrenals.
The anterior lobe of pituitary releases almost 6 hormones: STH,TSH,ACTH,FSH,LH and LTH... for the release of all these hormones, it needs a stimuli from the hypothalamus.eg: FSH RH (FSH Releasing Hormone)is released from the hypothalamus which orders the ant pituitary to produce FSH.. also the hypot. produces Inhibitors to inhibit the hormone production. thats y the old concept of pituitary as a master gland is now slowly fading away and it seems as if there exists a boss for the pituitary that is the hypothalamus.hope u r convinced abt this.
