Overview
Hyderabad: The article is in continuation to the last article about chemical cordination and integration in the human today. Today, let’s continue discusion the functions of the Pituitary Gland. The information can be handy for the upcoming government recruitment examinations.Pituitary gland• Prolactin regulates the growth of the mamary glands and formation of milk in them.
Key Information
• TSH stimulates the synthesis and secretion of thyroid hormones from the thyroid gland. • ACTH stimulates the synthesis and secretion of steroid hormones caled glucorticoids from the adrenal cortex. • LH and FSH stimulate gonadal activity and hence are caled gonadotrophins.
• In males, LH stimulates the synthesis and secretion of hormones caled androgens from testis. In males, FSH androgens regulate spermatogenesis. • In females, LH induces ovulation of fuly mature folicles (grafian folicles) and maintains the corpus luteum, formed from the remnants of the grafian folicles after ovulation.
FSH stimulates growth and development of the ovarian folicles in females. • MSH acts on the melanocytes (melanin containg cels) and regulates pigmentation of the skin. • Oxytocin acts on the smoth muscles of our body and stimulates their contraction.
In females, it stimulates a vigorous contraction of uterus at the time of child birth, and milk ejection from the mamary gland. • Vasopresin acts mainly at the kidney and stimulates resorption of water and electrolytes by the distal tubules and thereby reduces los of water through urine (diuresis). Hence, it is also caled as anti-diuretic hormone (ADH).
An impairment afecting synthesis or release of ADH results in a diminished ability of the kidney to conserve water leading to water los and dehydration. This condition is known as Diabetes Insipidus.To be continued…© Copyrights 202 TELANGANA PUBLICATIONS PVT. Al rights reserved.
