2.0 Experimental Approach Predatory cone snails (genus Conus) produce a rich array of venoms that collectively contain an estimated 100,000 small, disulfide-rich peptides (i.e., conotoxins, or conopeptides). Over the last few decades, the conopeptides have revealed a remarkable diversity of pharmacological function and utility. An evolutionary rationale for the existence of such a large and pharmacologically diverse set of gene products can be premised on the complexity of intra- and…

Bullfrog Dissection Background The American bullfrog, Lithobates catesbeianus, is an amphibian about the size of a teacup.(National Geographic, “American Bullfrog”). This dissection explored the anatomy of a bullfrog that had been pithed. Pithing is a technique used to prevent the frog from experiencing any cruel or unusual pain during the dissection. A pithed frog has had its nervous tissue in its brain severed thus allowing it to maintain normal bodily function during the dissection without…

Unbalanced hormones aren’t just problems for teenagers and older people. Hormones are our body’s control center. They are the chemical messengers that are created in the endocrine glands. These messengers control most major bodily functions, like hunger, reproduction, emotions and mood. As we age, environmental chemicals and processed foods can alter our hormones, causing a disruption of that delicate balance hormonal balance. Unbalance hormones can make it hard to lose weight,get pregnant,…

Just Add Hormones, by Matt Kailey (2005) is an autobiography of Kailey’s experience through becoming a transman. He talks about his experience as a heterosexual women, and changes after becoming a male. To me I am so interested in how everyday life can be so different just because of the genitalia you have. I could easily relate to every male experience, but I could not wrap my head around the idea of having to know the closest place to run for sanctuary at all times. When I read some things I…

This paper illustrates how oscillations can affect different hormones and specifically focuses on how oscillations of glucocorticoid hormones play a vital role in the circadian activity of hypothalamic-pituitary-adrenal (HPA) axis. To understand this concept, it is important to know what oscillations are and how they are impactful. It is widely accepted that all atoms oscillate or move. This occurs both in our environment and in our own bodies. Dynamic movement is actually necessary for us to…

The effect of human growth hormone of pituitary dwarfism in children and adults Introduction Human Growth Hormone is one of the major hormone found in endocrine system in your body. It is an essential hormone that stimulate the body growth, normal brain function and secreted by the somatotropin cells in anterior pituitary gland. There are a condition of abnormal body grow such as pituitary gigantism and pituitary dwarfism which the body over create grow hormone or doesn’t create enough GH.…

secrete hormones. Hormones are regulators of metabolism, growth, development, reproduction, and other activities. They also play roles in fluid and electrolyte balance, acid-base balance, and energy metabolism 1. One of the hormones is called the thyroid-stimulating hormone (TSH). The job of these hormones promote and maintain the growth and development; their target is the thyroid. Thyroid tissue is composed of tiny structural units called follicles, these are the sites where thyroid hormones…

glands which produce hormones, regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep, mood, in addition to a plethora of other things (Zimmermann, 2016). The glands included in this system are the pituitary gland, thyroid gland, parathyroid glands, adrenal glands, pancreas, ovaries in females, and testicles in males (Zimmermann, 2016). These glands are ductless and release their products into the blood or lymph. These products are hormones which come…

Triiodothyronine, with a chemical name of 3,3',5-Triiodothyronine (T3), is one of four thyroid hormones that exhibit biological activity, and contains 3 iodines and 2 tyrosine’s, as seen in Fig. 1. 20 % of T3 is formed from the amino acid tyrosine within specific follicle cells of the thyroid gland by the oxidative condensation of its biological precursors, monoiodotyrosine and diiodotyrosine, and is then subsequently secreted into the bloodstream. The remaining 80% is produced from the…

iodine in the food we eat to produce vital hormones like thyroxine or T4 and triiodothyronine, T3, both of which regulate the speed at which your cells metabolic processes function. The thyroid itself is regulated by the pituitary gland and hypothalamus and functions on a feedback system. Much like a thermostat, the body responds to the thyroid’s underproduction of hormones by causing the hypothalamus to produce a hormone called TRH (thyrotropin releasing hormone) which stimulates the pituitary…
