Capella University BIO1000 – Human Biology U01A1-Homeostasis-An Analogy January 12‚ 2012 Part 1 - Regulates your body temperature when you are outside on a cold winter day. When it is cold outside and the temperature drops‚ your body thermo receptors detect the drop and send signals to the hypothalamus. Neurons also send signals to smooth the walls of the blood vessels to make them contract‚ which creates a narrowing in the blood vessel also known as “vasoconstriction”. What vasoconstriction

Essay Describe and evaluate the synaptic homeostasis model of sleep The synaptic homeostasis model of sleep (Tononi & Cirelli‚ 2003) explains memory consolidation as a by-product of synaptic downscaling that occurs during sleep. This essay will describe the synaptic homeostasis model of sleep and evaluate how valid its predictions are in the face of empirical research. According to this model‚ synaptic potentiation is associated with the homeostatic regulation of slow wave activity‚ which

Anatomy and Physiology P5/M2 - Homeostasis Homeostasis is the need for an organism or a cell to regulate its internal environment (conditions within the fluid surrounding its body cells) by a system of feedback controls to stabilise health and functioning despite the outside changing conditions. This is important as this is what maintains and helps internal conditions (body temperature) to remain stable and constant. In humans homeostasis happens when the body regulates its body temperature in

10 Ways my Body Maintained Homeostasis By Travis Bushong 1. I was sweating after jogging a mile because my body’s internal temperature had gotten too high and I needed to cool down so my body used the extra internal heat to release sweat and at the same time keep homeostasis. The systems involved were my nervous system and my integumentary system. 2. When I was shivering after getting out of the hot tub it was my muscles moving quickly. Muscles need a combination of fats and sugars burned with

How well do the concepts of drive and homeostasis contribute to understanding sexual motivation? Both sexual motivation‚ hunger and thirst are biological motivations‚ a desire that directs behaviour (Myers‚ 2004‚ p. 420). However unlike sexual motivation which drives us to pleasure and procreation‚ hunger and thirst are needed to survive. In regards to the motivation behind hunger‚ drive reduction theory suggests that the bodys motivation to maintain homeostasis drives us to reduce our need for hunger

1. Briefly explain how does the body maintain homeostasis? Homeostasis is a existence and maintenance of a relatively constant internal environment. Homeostasis is maintain by negative and positive feedback mechanism. Most homeostatic control mechanisms are negative feedback mechanisms. In these system‚ the output shut off the original stimulus or reduce its intensity. These mechanisms cause the variable to change in a direction opposite to that of the initial change‚ returning it to its “ideal”

Assessment of Patient The assessment of Mrs. Baker should include vital signs including pulse oximetry. Given her difficulty in breathing‚ lung sounds should be auscultated. Because she is on two different medications that could affect blood pressure‚ lisinopril and hydrochlorothiazide (HCTZ)‚ hypotension could be one cause of her collapsing. In addition

Homeostasis is important in maintaining a healthy functioning of the body. Enzymes within the body are vitally responsible for speeding up chemical reactions and are often referred to as catalysts. In order to work at their optimum‚ enzymes need a specific constant temperature within the internal environment of the body to function correctly and reduce denaturing. A healthy human body should have a body temperature of 37∙C‚ the optimum temperature for enzymes to function. Therefore‚ the temperature
