The most rudimentary explanation for what causes obesity is the relationship of energy intake and expenditure and its effect on energy balance. If energy intake is greater than energy expenditure, weight gain will occur. In contrast, energy expenditure in excess of energy intake will result in weight loss ( Dietz & Gortmaker, 2001). However, Obesity is a complex disease that involves interactions between genetics, regulation of energy balance, and strong environmental influences such as increased

of the argument. In an attempt to understand the cause of homosexuality, researchers began by examining the anatomy of the brain, particularly in primate species. Slimp, Hart & Goy (1976) established the role of the medial preoptic – anterior hypothalamus (MP-AH) by making radiofrequency lesions bilaterally on adult male rhesus monkeys. By doing so they observed that the males still possessed a sex drive (masturbation and yawning – a sexually dimorphic behaviour), but would refuse to have sex with

Hormonal theory does not describe a cause of homosexuality. Genetic Theory describes the cause of homosexuality as people being born gay. The brain theory is much more in depth about the cause of homosexuality. It states that the size of a person’s hypothalamus will cause them to be homosexual or not. Gay’s hypothalamuses were less than half of the size of straights'. The sociological perspective of deviance describes society and socialization to be the causes of homosexuality (Taylor, Thio & Schwartz

The results lead that they were the cause of the manifestation of the traits of IRX3. “While Irx3 expression was detected in the actuate nucleus of the hypothalamus, three enhancer sequences isolated from the LD block drove expression in lung and several brain regions, but not in hypothalamus” (Rinkwitz 2015) The question that is lurking in the researchers mind were, does FTO intro 1 have any connection to the growth of the IRX3 gene regulatory? Therefore they introduced

and not by an organ, it actually is. Life, memory, etc. are all from the brain. My growing knowledge of the brain even helped me to stay composed even when I get irritated. I think to myself, “Okay, these negative signals are being sent to your hypothalamus and the signals of how you will react will be sent to your amygdala. It is not you, these feelings are just sent to your brain.” This helps me to almost take control of myself. I am researching the brain and using it in my everyday life. The knowledge

As I scope out my first victim, I have chosen to devour the brain stem. Yes, it may be a bit tricky to get to since it rests on the lower portion of the brain, but after I eat that part I will have more heightened and complex parts of the brain to eat rather than just the old brain before the evolution took place. It will be worth it to eat to be able to enjoy more delectable items. I will also no longer be able to hear their incessant breathing and pounds of their heart. I will be able to devour

ghrelin and less leptin. This will result in an increase in appetite and reduce the burning of calories. Another example is when you reduce your food intake when dieting; ghrelin production is increased. This increase sends a signal to your hypothalamus that you need to eat more. It is this lack of sleep that forces your body to work against itself and not maintain and optimal environment for a healthy weight. Regular exercise helps to regulate ghrelin and leptin production. Exercise normalizes

8. Thermoregulation is keeping the temperature of an object in this case the human body stable or in a controlled temperature. 9.The hypothalamus is what contains sensors that monitor the body temperature. 10. a. The body's two mechanisms for cooling itself are dilating blood vessels and increasing sweat production in the sweat glands. b.The body's two mechanisms for generating heat are shivering muscles and constricting blood vessels in the skin. 11. a.The stimulus is the temperature being

ways homeostasis can be achieved by an animal. For instance, let’s say a dog is in a cold environment and in order for its body to maintain a normal body temperature it begins to shiver. When a body temperature decreases a message is sent to the hypothalamus (which is like an internal thermostat) and then activates a warming mechanism. Once the brain sends this message to the blood vessels, the blood vessels then begin to constrict, as an outcome, their skeletal muscles begin to contract, causing them
