Essay on The Endocrine System Exam

9. Which of the symptoms that Y.L. reported today led you to believe she has some form of neuropathy?

The vagaries of human hormones have interested me since I watched all five of my dad’s siblings get diagnosed with diabetes. Watching adults check their blood sugars and teach each other to use syringes became routine at family gatherings. I tried to understand how to avoid this seemingly genetic inheritance was what drew me to pursue medicine in the first place. Now as I look to the next stage of my education, Endocrinology is the most apt field for me. While reading about a particular case in the Endocrine clinic, I came across a quote by an Endocrinologist who described the field as, “a discipline that provides continuing intellectual stimulation, pragmatic satisfaction, and great promise of discovery.” This clearly delineated all the attributes of Endocrinology that I look forward to, and my training thus far has prepared me to take this next step.

In this experiment, contractions of the earthworm gut are measured in an organ bath with a force transducer. The effect of neurotransmitters and ionic concentrations on contraction strength and rate will be investigated.

12. Both the nervous system and the endocrine system are used to convey messages throughout the body and coordinate organs, systems, and behavior. Compare and contrast how these two systems function.

5. What are “lipids?” Some lipids are liquid at room temperature whereas other lipids are solid at room temperature. What accounts for this difference? Are all fats considered to be lipids? Are all lipids considered to be fats? If not, what else besides fats are considered lipids? What distinguishes “lipids” and “phospholipids?”

*Endocrine glands produce – hormones, they work with other hormones to perform many functions including: control water & electrolyte balance, regulating carbohydrate metabolism, working as neurotransmitters, maintaining stress & inflammation, regulate reproductive functions

9. What are the three types of capillaries, and what functions do each serve? How is the blood brain barrier created? What are the forces that control movement of substances through the capillary wall (be specific)? How is lymph formed?

The endocrine system is a group of glands distributed throughout the human body. This group of glands secretes substances called hormones. These hormones are dumping into the bloodstream (Shier, Butler & Lewis, 2009). The endocrine system does not have a single anatomic location. It is dispersed throughout the human body. The final purpose of this process is to control, regulate, and coordinate the functioning of the human body. Some body functions can be activated or inhibited by hormones, which are secreted in very small quantities. The hormone related diseases may be due to hyper secretion, or a hypo secretion. The hormones secreted by the endocrine glands regulate growth, development and function of many tissues, and coordinate the

During recent years, numerous newspaper and magazine articles have suggested that humans may be at risk because small amounts of well known environmental contaminants, such as dioxin, PCBs and DDT, can affect hormone levels. Hormones are produced by the endocrine system as regulators of biological function in target organs. Because hormones play a critical role in early development, toxicological effects on the endocrine system often have an impact on the reproductive system. The term endocrine disruptor is used to describe chemicals that can mimic hormones and may either enhance or counteract their effects. It has been suggested that these hormone changes can, in turn, lead to a variety of health problems

There is a pair of kidneys in the human body. They are situated towards the back of the body under the ribs, just at the level of the waist where one on either side of the body. Each kidney is composed of about one million units which are called nephrons and each nephron consists of two parts: a filter which is called the glomerulus and a tubule leading out from the nephron (Cameron 1999). According to Marshall and Bangert (2008) the kidneys have three major functions. Firstly, the kidneys are excretion of waste from plasma in the blood. The second function is that, they maintain of extracellular fluid volume and composition. Lastly, the kidneys have a role in hormone synthesis.
