Homeostasis is a characteristic of life in which all Living things maintain. some of the traits of Homeostasis are perspiration and some form of breathing and other natural body functions. An example of a negative feedback mechanism is a Thermostat If the heat is turned on and is set at 80 degrees the heat is turned on, If the temperature drops below 80 degrees, After the heater heats the house to 80 degrees, it shuts off keeping the desired temperature. An example of a positive feedback system is when a baby is born. while the mother is in labor, a hormone is released that boosts and quickens her contractions. The more contractions causes more of that Hormone to be let out and it continues to goes on until the

homeostasis. Joint homeostasis is maintain with the balance between build up mechanism and break down mechanism of the joint. Imbalance homeostasis occurred when anabolic effect is slower than catabolic effect of the joint. This will result in joint instability (Goldring MB, 2006).

Homeostasis is the process of maintaining a fairly constant interval environment. Homeostatic mechanisms help us to be independent of our external environment. It helps us regulate our body temperature, pH, concentration of dissolved substance in the body fluids, concentration of glucose in blood, concentration of oxygen and carbon dioxide in the blood and body fluids, blood pressure and concentration of metabolic wastes. Without it, we wouldn’t be able to survive and adapt to our environment.

Homeostasis is a biological process that maintains a constant internal environment, regardless of what is going on in the external environment. This process ensures the bodily functions and chemicals are kept in a state of balance which in return allows the body to function optimally. Homeostasis requires coordination of the hormonal (endocrine system) and nervous systems, which together regulate the activity of the body’s organ systems. The regulatory activities are constantly adjusted in response to stimuli (change) from both the internal and external environment. A change influenced by the external environment can cause a state in the body that will take it away from the normal, the body will act to counteract this change and return the internal environment back to a steady state. This is negative feedback. Negative feedback has a stabilising effect reducing changes from a set point and returning internal conditions to a steady state. Most body systems e.g. controlling blood glucose levels, obtains homeostasis through negative feedback which makes the negative feedback system critically important in obtaining homeostasis. However there is also positive feedback which is a system that results in the escalation of a response to a stimulus. It causes instability in the system and is used when there is a specific outcome required. Positive feedback ceases once the natural resolution is reached e.g. baby is born, pathogen is destroyed, blood clot forms. This system is not used

In Abraham Maslow’s theory of self-actualization, the first level is basic needs. The basic needs consist of survival necessities, basic needs are the lowest level of the hierarchy. Some of these basic needs are the need of air, food, drink, shelter, warmth, sleep. Only after meeting the basic lower-order needs can a person fulfill higher-order needs, such as the needs for love and a sense of belonging, esteem, and self-actualization (http://www.simplypsychology.org/maslow.html.) People have a physical need for homeostasis, which is the body’s tendency to maintain a steady internal state, underlies primary drives. The biological needs of a person are motivated the drives of a person, such as hunger, thirst, sleep, and sex, which are related to the biological needs of the body. Motivation is

In the introduction and chapter one of Drive: The Surprising Truth About What Motivates Us, Daniel H. Pink expressed how behavioral science can change the common understanding of people’s driving force and suggests a more helpful way to better performance. Pink mentioned that there are two main drives that are powered by behavior. First is the biological drive which comes from within individuals and the second drive comes from without rewards and punishments the environment provides for performing in particular ways. However, a scientist named Harry F. Harlow came up with a third drive after experimenting with monkeys and Harlow called it the “intrinsic motivation.” Harlow said that to completely comprehend the human condition, people have

Four-Drive theory is a motivation theory that is based on the innate drives to acquire, bond, learn, and defend, and that incorporates both emotions and rationality.

Homeostasis Homeostasis works to maintain the organism's internal environment, where the body's processes are able to function at a level that would allow life to continue in that organism. The three systems which are controlled by homeostasis are the respiratory, cardiovascular, and muscular systems. Changes to the cardiovascular system are often a result of changes in the activities of other systems.

Homeostasis is the ability of the the body to maintain a stable internal environment despite changes. For example, “The body can control temperature by making or releasing heat.” When the body is making heat it and releasing heat it is in order to maintain the usual human body temperature, 98.6 degrees Fahrenheit. Senses is a faculty by which the body feels an external stimulus: one of the faculties of sight, smell, hearing, taste and touch. A sense organ, or sensor, dedicated to each sense, sight (vision), hearing (audition), taste (gustation), smell (olfaction) and touch (somatosensation) are the five traditionally recognized senses. The five senses are located on different parts of the human body, for example, the eyes translate light into

Motivation and theories -------------------------- 2.1. Definition and theory framework ------------------------------------ Motivation can be described as the driving force of individual behaviour to fulfill needs or achieve goals. Mitchell defines motivation as 'the degree to which an individual wants and chooses to engage in certain specified behaviours' (Mullins 2002:418). In terms of this definition, various theories have been developed around.

This theory states that one cannot learn unless there is a drive that forces one into action to produce some kind of reward. This satisfies the drive and reduces the psychological or physiological need. (Drive Reduction Theory, 2011). An example of a psychological need is a desire for love. One will seek out others to be a part of one’s life. An example of a physiological need is hunger. One will look for food when hungry.

The term I would like to introduce today is Homeostasis. This term is used in psychology and means having balanced body or life. A simpler definition to keep things constant, or in a balanced flow. This could be an organ in the body, your mind, or simply the area of your life. It is important for us to know what homeostasis is because, we all need balance in our lives. Psychology today says “Homeostasis is critical to survival. If our bodies do not maintain themselves within certain tolerances (temperature being one example) we cannot function. Growing through creative change is also critical. If we cannot adapt to shifts in our environment (changing food sources being one example) we cannot function either.” (psychologytoday)

‘Motivation’ is derived from the Latin term ‘movere’ that means ‘to move’. Thus, motivation is a process that starts with a physiological or psychological deficiency or need that activates a behaviour or a drive that is aimed at a goal or incentive (Luthans). Broadly speaking, motivation is willingness to exert high levels of efforts towards organizational goals, conditioned by the efforts’ ability to satisfy some individual needs (Robbins). Need means some internal state that make certain outcomes appear attractive. An unsatisfied need creates tension that stimulates drives within the individual. These drives generate a search behaviour to find particular goals, that if attained,
