Homeostatic Control Of Blood Glucose Levels Essay Help

Does sweating involve both the endocrine system and the nervous system?

Silly question, but is sweating an example of where both the nervous system and endocrine system work together? Electrical signals are sent to sweat glands, but as they're glands, surely that also makes it endocrine as well due to the secreting? (or exo as nothing is being secreted into the blood). In the hot/cold table, it is not clear which involves the endocrine system, and which involves the nervous system

Sweating involves both the endocrine and the nervous systems. To regulate the body temperature, the following process happens. There are sensory receptors (part of the nervous system) that can feel the increase of body temperature. Once the body temperature increases, these small receptors feel the increase of the body temperature and send a message to the hypothalamus through sensory neurons. The hypothalamus (belongs to both endocrine and nervous systems), after interpreting the signal secretes a hormone that is carried out by the blood vessels to the sweat glands (effector organ). Once the sweat glands become activated by this hormone, they secrete sweat, thus releasing heat and reducing the body temperature to its normal.

How does homeostatic help control my body temperature?

Using the terms receptors, control center, and effector, explain the homeostatic mechanisms involved in controlling body temperature. Need it for revision on the upcoming exam, don't fully understand it yet. I have tried: Reading other articles, visiting various sites, going over uni lectures. I think it was caused by: I don't understand the explanation, too much information, the way in which my lecturer explains it to me.

To regulate the body temperature, the following process happens. There are sensory receptors that can feel the increase of body temperature. These sensory receptors are like small detectors that can sense any change in the temperature of the body. Once the body temperature increases, these small receptors feel the change and send a message to the hypothalamus through sensory neurons. The hypothalamus (the control center in the brain for the regulation of homeostasis), after interpreting the signal secretes a hormone that is carried out by the blood vessels to the sweat glands (effector organ). Once the sweat glands become activated by this hormone, they secrete sweat, thus releasing heat and reducing the body temperature to its normal.

Describe generally how a NEGATIVE feedback loop works it comes to temperature regulation of the body.

Once the body temperature increases, the hypothalamus is activated that in turn activates the sweat glands to release sweat and reduce the body temperature. When the body temperature decreases, this message is sent to the hypothalamus by a negative feedback to stop activating the sweat glands. Thus, when the sweat glands are not activated, no sweat is released and the temperature returns to its normal value. (Remember the body temperature should remain constant at all times, therefore, after some time the release of heat should stop and this is done by a negative feedback mechanism)

An important aspect of homeostasis is maintaining a normal body temperature?

An important aspect of homeostasis is maintaining a normal body temperature. Describe the homeostatic feedback system that would be activated in response to a decreased external temperature

Yes, homeostasis is important to keep everything in the body balanced. The temperature of the body is around 37ºC at all times. If this temperature decreases, it will result in hypothermia (low body temperature), and when it increases it will result in hyperthermia (high body temperature). Both cases are not healthy for the body to function properly and can lead to problems and diseases. When it is cold outside, our body temperature also drops (below 37ºC). The receptors on the blood vessels, that detect these signals, are activated and transmit signals to activate the hypothalamus. The hypothalamus will send signals to the blood vessels. The blood vessels will start constricting to retain heat. It also sends signals to the sweat glands and as a result, these glands will stop secreting sweat. The skeletal muscles are also alerted by the hypothalamus that starts shivering to warm up the muscles and produce heat.

Hi, In order to write a good essay about negative feedback of homeostasis, first you should start your essay by defining homeostasis. Then, explain the two types of homeostasis. Talk briefly about positive feedback, and then mention that this essay is about the negative feedback. After explaining negative feedback mechanism, give examples to go deeper into how negative feedback works. And as a conclusion end your essay about the importance of negative feedback mechanism.

How is skin involved in either in homeostasis?

The skin is the largest organ in the human body. And as all organs have a role in homeostasis, the skin plays an important role. The nerve endings in your skin identify changes in temperature and send signals to your brain that your temperature is rising or dropping. Your brain will process these signals and initiate effectors to start regulating the body temperature. Blood flow to the skin also helps regulate body temperature and sweat glands may release sweat through the skin to help decrease temperature. Your skin may also form goosebumps, designed to help you warm up. These are just some of the ways the skin is an important element in homeostasis and negative feedback.

The brain responded to the demands of exercise by increasing respiration and heart rate. How do these changes contribute to the maintenance of homeostasis?

During exercise, your entire body works hard to maintain homeostasis. When you exercise your muscles are working hard and your body works to ensure the right levels of oxygen are reaching your cells. This increases your breathing rate and also releases carbon dioxide. If too much carbon dioxide builds up during exercise it can lead to a build up of lactic acid during exercise. Lactic acid build-up can inhibit your ability to exercise effectively. This need for oxygen also explains why the heart rate increases. Your body is trying to make more oxygen by pumping your heart harder and moving blood and oxygen away from non-working parts of the body to ones that are working hard. When your body exercises is converts food into energy. This conversion produces a waste product: heat. To try and decrease your temperature, your body will make changes to enable blood flow to the surface of your body and disperse the heat. You will feel this in sweat.

What could cause a sudden Hypothermic Reaction - random and no obvious cause?

I've been trying to find out why a patient has a sudden and extremely rapid temperature loss. Within space of no more than 30 seconds, temperature reduces rapidly over whole body - head, legs, arms, face. Face and hands go white. . . When temperature comes back after applying heat treatments, there is pain in back described as "squeezing" by patient.. . Heart monitoring (internal monitor) shows decrease in heart rate but not below critical thresholds.. . If standing, will feel dizzy.. . It seems there are some trigger events, for instance, a slightly colder environment, but this can also happen on a hot or warm day or inside a heated building. Tests done for thyroid and diabetes proved negative, and also Raynaud's phenomenon ruled out. I have tried: Hand heating pads, blankets, hot water bottles can restore body temperature but the problem is diagnosis. I think it was caused by: The heart consultant at the General Hospital has no idea. Two A&E doctors observed it and have no idea. Clearly it is not a phenomenon which effects a large proportion of the population.

Homeostatic Control of Blood Glucose Levels Essay

Homeostatic Control of Blood Glucose Levels

Glucose is an essential substance in the body as it is the primary source of energy for all biological functions and is indeed the only form of energy which can be used by the brain and central nervous system. The ideal level of blood glucose is 80 - 90mg of glucose per 100mls of blood. However this level is not static - it oscillates due to changes in the body which are brought about by actions such as eating a meal, exercising, or not eating for long periods. If blood glucose levels drop or rise dramatically there may be serious consequences such as hypo- or hyperglycaemia which can both cause death. Thus it is necessary for blood glucose levels to be…show more content…

The level of blood glucose is constantly monitored by the beta cells. As the effects of insulin bring down the blood glucose level the cells secrete less and less of the hormone in accordance with the falling level of blood glucose - this continues until levels return to normal.

The corresponding effect of this antagonistic mechanism occurs when blood glucose level have fallen too low - this is detected in the Islets of Langerhans by the alpha cells which are stimulated to produce glucagon. This hormone acts in two main ways to raise blood glucose concentration back to normal levels. Firstly, it stimulates the process of glycogenolysis whereby the liver and muscle cells convert glycogen into glucose to be discharged into the blood. In addition, it increases gluconeogenesis so that more glucose is synthesised from protein and fat sources. However if glucagon is allowed to encourage the production of glucose unchecked, the liver will begin to produce ketones which dangerously disrupt the acid/base balance in the body. The two
