Pituitary Gland Case Summary

5. If the pituitary is so important, and Eric is not getting replacements of hormones the pituitary makes (except for the one from question 4 above), why isn’t he dead? To answer this question think through the cascade of events from the hypothalamus to effect. You will need to think about homeostatic feedback loops and the regulations of hormones. Before we can discuss why Eric is alive without a functioning pituitary gland we must first understand how the pituitary gland functions within the endocrine system. The pituitary gland is a pea sized gland that sits at the base of the brain and is attached to the hypothalamus by the pituitary stalk (infundibulum). The pituitary gland consists of two different portions, the anterior lobe and the posterior lobe. The anterior lobe is responsible for synthetization …show more content…

Low testosterone affects more than just a male’s sex drive. Testosterone affects many other aspects of a male’s health, particularly his overall bone health. Low levels of testosterone can lead to osteoporosis and some studies even say it can affect life expectancy. Since Eric’s cause for low testosterone is due to lack of FSH and LH production from the pituitary his condition is referred to as secondary hypogonadism. There are many different treatment options for testosterone replacement, there are gels, pills, shots, patches and long acting pellets. These treatments bring testosterone levels back into normal ranges which can be monitored by simple blood tests. Bringing testosterone levels back to normal ranges would not help Eric with his issue of being sterile. Eric is sterile because his pituitary gland does not secrete LH and FSH which responsible for sperm production in the testes. Sterility would have to be treated with replacement therapies of LH and FSH. If Eric is strictly trying to maintain testosterone levels then the above mention therapies would be

He doesn’t have an extensive case of this disorder but he does take medication to treat it. I prescribed him dexamethasone when he was first diagnosed with this disorder fifteen years ago.

The posterior lobe is then responsible for storing the hormones made by the neurons of the hypothalamus. The hypothalamo-hypophyseal portal system is the specific way the hypothalamus communicates with the anterior lobe of the pituitary gland. This portal system consists of blood vessels that carry hormones of the hypothalamus to the anterior lobe. The anterior lobe then responds by making its own hormones. The anterior lobe hormones can go and control other glands.

The anterior pituitary is devoid of a nerve supply, but has a unique blood supply, a portal system. The hypothalamohypophyseal portal system begins in a series of capillaries in the median eminence of the hypothalamus sends blood via veins to the anterior lobe, where it ends in a series of capillaries. This portal system carries neurohormones from the hypothalamus to the anterior pituitary where they control the secretion of anterior lobe hormones. The anterior pituitary consists of five different endocrine cell types, identified by antibodies against pituitary hormones and capable of production and secretion of pituitary hormones: 1.

Essay On The Endocrine System

820 Words | 4 Pages

The endocrine system is such an important system to the body because it functions the bodies use of hormones. The body uses many different hormones and the endocrine system regulates these. When the glands of the endocrine system secrete the hormones, the hormones are put into the bloodstream to be sent to the different parts of the body. The glands that comprise the endocrine system are the hypothalamus, the pituitary gland, and the pineal gland which are all located in the brain, the thyroid, parathyroid, and thymus which are located in the throat, the adrenals and pancreas which are located in the body’s midsection, and the ovaries (female) and testes (male) which are located in the pelvic region. The system is so important because it regulates the body’s metabolism, growth and sexual development, digestion, heart rate, and many of the other body functions regulated by hormones.
