Homeostasis is what allows our internal system to maintain at a constant condition. In order to maintain equilibrium the body must communicate using the control system. It is essential that the body monitors its conditions whether that be blood pressure, thirst sensation or body temperature (this is either gained or lost). Negative feedback is most important and comes first, this allows for the body to correct itself and get back to a set point when it is off track. There are three components that link with this feedback. A sensor (receptor) sends signals to the control center that something is unusual, the control center compares the many values of our normal body range and decides

The thyroid gland is found in the front of the neck and produces two main hormones. The hormones are called thuroxine (T4) and Triiodothyronine (T3). Together these hormones regulate the body’s metabolism by increasing energy use in cells, regulate growth and development, help to maintain body temperature and aid in oxygen consumption. These two hormones are regulated by hormones produced by the hypothalamus and pituitary gland. The hypothalamus senses changes in body’s metabolic rate and releases a hormone known as thyropin-releasing hormone (TRH). This hormone then flows through connecting vessels to the pituitary gland which signals it to release another hormone. This hormone is known as thyroid-stimulating hormone (TSH). TSH then makes

Gastroesophageal Reflux Disease or GERD, also known as Acid Reflux, is a chronic disease that happens when stomach acid flows back into your esophagus, causing irritation and discomfort. Gerd is a disease that deals with your stomach, esophagus and lower esophageal sphincter (LES). The acid that is consumed from different contents like food and liquids can escape through the LES, which is the gateway of food and acid into the stomach. The main responsibility of the LES is to keep the acid and food in your stomach, however when your LES is weak, this can cause acid to flow upward back into your esophagus and cause GERD (PDR, 2016).

Enclosed please find my application for Anatomy Instructor at Jacobs School of Medicine and Anatomical Science. I feel confident that I would be an ideal addition to the teaching faculty at the Department of Pathology and Anatomical Sciences, as you will observe that my experiences, researches and future plans are highly compatible with a number of your current faculty members. Moreover, I am presently enrolled in masters in Anatomical Science program, which further polished my teaching skills by incorporating a thesis project, graduate course-work, a teaching practicum, anatomical specimen preparation and dissection techniques. My colleagues and I are presented with a number of far-ranging opportunities from learning how to use an electron

Thyroxine is the main hormone secreted into the bloodstream by the thyroid gland. Thyroid hormones play a vital role in regulating the bodys metabolic rate, heart and digestive function, muscle control, brain development and maintenance of bones.

My hand was sprinting across the page with charcoal in palm, and the finish line of my sketch was in sight. The image of a model’s face was quickly appearing, and the proportions of her eyes-to-nose and ear-to-mouth were just right. Proportions of the human face were something I learned in art class, whereas the details in her eyes were something I learned in anatomy class.
