Thirst Sensation And Return To Homeostasis
Thirst sensation is a negative feedback. The sensation of thirst is important for maintain osmoregulation. Osmoregulation is responsible for preventing too much or too little of water in your cells. The osmoreceptors in the hypothalamus detect when their low or excessive amounts of water in your blood. If you drink when the water amounts are low, this will increase the amount of blood water content and return to homeostasis. If you do not have the thirst sensation and do not drink, this will decrease the amount of blood water content and return to homeostasis. However, there are alternatives for both. With low amounts of water and not drinking, your body must go through more steps such as creating more antidiuretic hormones and collecting water

    One way in which eating behaviour is controlled is by a process called homeostasis. This involves mechanisms which both detect the state of the internal environment and also correct the situation to restore that environment to its optimal state. The body has evolved two separate systems, one for turning eating on and another for turning it off. Glucose levels play an important role in producing feelings of hunger. When there is a decrease in blood glucose, this increases the feeling of hunger which is activated by the lateral hypothalamus in the brain. This contains a neurotransmitter called the neuropeptide Y which causes the individual to consume food, therefore resulting in the glucose levels to rise again. This rise in glucose levels activates the ventromedial hypothalamus which leads to feelings of satiation. The ventromedial hypothalamus contains an area called the paraventricular nucleus which is believed to cause a condition called hyperphagia (over eating). This is turn inhibits further consumption until the blood glucose levels have decreased again.…

    Hunger Motivation

    • 996 Words
    • 3 Pages

    Hunger is one of the three most significant motivators a person experiences. It is a major concept in our everyday lives that influences behaviours we gravitate to ourselves. What drives this motivator? What are the mechanics and processes involved with feelings of hunger and fullness? For a better understanding starting from the biological aspects that soon combine with social aspects will develop a thorough sense of how hunger operates. A reliable process to accurately indicate true hunger is by the use of the blood glucose level. Levels are monitored through glucoreceptor cells in the brain and liver, of which we are not aware of our levels and is a good thing. It is not an ideal behaviour to constantly think about your blood glucose level every day of every minute. In addition to monitoring our glucose levels, the brain also monitors other factors such as hormone levels that operate the hunger mechanics. There are four hormones associated with hunger: cholecystokinin, leptin, glucocorticoids, and ghrelin. Cholecystokinin and leptin reduce the appetite when its levels are increased. In contrast, glucocorticoids and ghrelin enhance the appetite when increased in the body. A special tool of the brain is used in detecting the levels of the hormones to initiate the feeling of hunger or fullness. This tool is called the hypothalamus which used key areas to function the hunger mechanic. It also interacts with another part of the brain called the hippocampus in the experience of hunger and fullness. The lateral hypothalamus when stimulated will increase appetite but reduce it if it has sustained damage. The ventro-medial hypothalamus operates in the opposite way as it reduces appetite if stimulated but increases it if damaged. Specific types of hunger or “cravings” as one would call it are controlled by the paraventricular nucleus part of the hypothalamus. With this information, could we not develop ways to mold people’s appetites and over eating? Some would…
