Explanation / Answer
Thyroid Stimulating Hormone (TSH) Growth Hormone (GH) Melanocyte-Stimulating Hormone (MSH) Prolactin (PRL) evidence :- pituitary tumor is an abnormal growth of pituitary cells. Pituitary tumors can either be nonfunctional (that is they do not secrete hormones) or produce specific hormones, such as prolactin (causing infertility, decreased libido, and osteoporosis), growth hormone (causing acromegaly), ACTH (causing Cushing's), TSH (causing hypothyroidism), or be nonfunctional (that is they do not produce hormones) An imbalance occurs, leading to more than a dozen disorders of the endocrine system. Deficiency of thyroid hormone, adrenal cortical hormone (cortisol) or antidiuretic hormone (vasopressin) is rapidly life-threatening. In patients with abnormalities of the other hormones, quality of life is significantly compromised. symptoms:- These hormones have dramatic effects on metabolism, blood pressure, sexuality, reproduction, and other vital body functions. In addition, the pituitary gland produces growth hormone for normal development of height and prolactin for milk production.
