Understand how homeostatic mechanisms operate in the maintenance of an internal environment Homeostasis is keeping the body balanced to allow cells to function‚ despite external environment. Homeostasis is important because the cells‚ blood and tissue fluids can change by slowing down or even stop a vital chemical reaction. Its aim is to keep the body to stay the same‚ at a normal condition. Negative feedback is when change is detected; there are steps when change is detected to get it back

Common Fibular Nerve Lesion Following a Tibial and Fibular Spiral Fracture: a Case Report By: Jose Shimokawa SPT Introduction Tibial fractures are the most common long bone fractures and frequently associated with fibular fractures—in part‚ due to forces being transmitted across the interosseous membrane to the fibula.1 Fractures are generally managed by closed reduction or open reduction internal fixation (ORIF)‚ 2 which is usually followed by a period of immobilization. The most common impairments

Enzymology‚ Catalytic Mechanism‚ Carbohydrate Metabolism‚ Adenosine Triphosphate Enzymes are proteins and their function is to act as catalysts to speed up certain chemical reactions in the cell that would be slower without them. This process occurs as steps in a cycle with separate reactions in each step. If there is a missing product the step in the cycle will be incomplete and the normal function of the organism cannot be accomplished causing negative effects on the organism. The biological

Artikel: A conceptual framework for the design of organizational control mechanisms Problem: When a team of individuals produce a single output the problem arises on how to contribute the reward so that every individual is equally rewarded. This article examines three different mechanisms to deal with this issue: 1. Markets Markets deals with the control problem through precise measurement and reward of individual contributions. 2. Bureaucrats Bureaucrats rely on a mixture of close

carriers used to “build” the membranes? The molecules have to rely on carrier porteins which varies in number due to the available membrane transport. 2. Does the diffusion rate of Na+/Cl- change with the number of receptors? yes 3. What is the mechanism of the Na+/Cl- transport? 4. If you put the same amount of glucose in the right beaker as in the left‚ would you be able to observe any diffusion? No 5. Does being unable to observe diffusion necessarily mean that diffusion is not taking place

Discuss the role of Defence Mechanisms in Freud’s model of the mind. One of the pioneering Freudian assumption which is ‘psychic determinism’ sates that there is always explanation for particular behaviour and the motive of this behaviour can be found in the mind. In continue to this statement Sigmund Freud in his further work‚ evaluated almost entire variety of human behaviour and the role of the mind as its central coordinator. Following this he proposed a novel framework of the mind with its

What theories did people developed to try to explain the origins of disease? Through the years‚ the spread of diseases developed around the word. Many people didn’t understand what the cause of disease‚ so they believed evil spirits was the cause of sickness. These people use multiple of methods to find a cure as they: prayed to God‚ visited witch doctors to do spells‚ and special ritual dances to find a cure. People created these theories to explain human disease for millennia. Even the Greek physician
