Christman 1 Tiffany Christman/FTMYERS Professor Hazel HHSM/Research Week 3 22 March 2010 Create a list of each of the endocrine glands, the hormones they produce, and the effects of the hormones. Using a direct translation of the word endocrine, it means to secrete within and though the purposes of each different gland’s hormonal secretion is different, they all work in the same manner, releasing a chemical throughout the body (Barnes). I found many conflicting resources in researching the endocrine system; some alluding to only seven or eight glands and others up to nine and ten. Some of the contradictions I found debated the inclusion of the hypothalamus as its own separate gland or that it is part of the pituitary gland, and the hypothalamus as part of the thalamus, which in some sources was not indicated to be a gland at all. Yet noting that much of the research and knowledge we do have on endocrine glands has been done in my lifetime, it makes sense that there is a good deal of confusion as to their functions and classification. As this isn’t the period of da Vinci and other medical researchers of generations previous, thus cutting apart human bodies for study is a bit taboo, so they are left to study animals and other species and attempt to draw parallel conclusions. “The pituitary is essential to normal life,” stated Dr. Fussell in his work, Monographic Medicine (Fussell 515). And while it is true that the pituitary does appear to control all other glands within the body, the hypothalamus gland instigates the pituitary and would to this researcher appear even more essential. The pituitary gland visually looks like the aril of a pomegranate, not only in size but also in colour with a bright crimson bulb at the base and the

Christman 2 hypothalamus at the crown. I found it interesting that these are formed during gestation as tissue in the roof of the mouth grows upwards while a tissue in the brain grows downwards and eventually the two tissues merge to form the pituitary gland, complete with attached hypothalamus (Bowen). The hypothalamus connects the endocrine system to the nervous system, working with neurons in the brain to signal to the pituitary gland the appropriate actions, as discovered by Roger Guillemin and Andrew Schally (Nobel Foundation). The secretions of the hypothalamus are neurohormones and regulate body temperature, emotions, sexual response, response to stressors, growth of the body and body parts, response to pain through thyrotropin- releasing hormone also known as TRH, gonadotropin-releasing hormone referred to as GnRH, corticotrophin-releasing hormone called CRH and gastrointestinal neuropeptides, respectively (Farr). From the secretions received from the hypothalamus, the pituitary gland then sets in motion responses from other glands and parts within the body. For example, upon receiving stimuli related to growth, the pituitary releases a hormone called somatropin, which then travels through the body to tissues and bones and muscles, signaling growth.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
