What is negative feed back in terms of controlling conditions in the body?
Negative feedback is a regulatory mechanism in the body that works to maintain homeostasis by counteracting changes from a set point. For example, in temperature regulation, negative feedback will work to lower body temperature if it rises above the set point. This helps to keep the body systems functioning optimally.
What is homeostatic mechanism?
A homeostatic mechanism is the property of a system, either open or closed, that regulates its internal environment and tends to maintain a stable, constant condition. For example: the hypothalamus (which is a homeostatic mechanism) senses when your body's temperature is too high or too low. In a situation where the temperature of your body is above normal, the hypothalamus senses that a change needs to be made in order to reverse the heating of the area and reduce the amount of blood that is sent to the location. In turn this action will cool the body and return it to the normal temperature in which it should be maintained.
What is homeostatic regulation?
Homeostatic regulation is controlled in the body by the autonomic nervous system and seeks to maintain relatively stable conditions in the internal environment. The main gland of homeostasis is the hypothalamus and the major organ of homeostasis are the kidneys.
What is the importance of temperature-regulating mechanisms in organisms?
The hypothalamus is responsible for the regulation of temperature in organisms. It is important because temperature directly affects vital biochemical processes within the body. Without a regulating mechanism, the organism will die.
How atropine cause hyperthermia?
Atropine antagonises central muscarinic receptors (remember, the parasympathetic nervous system is made up of muscarinic and nicotinic receptors). This muscarinic receptor antagonising alters temperature regulation in the hypothalamus -- the mechanism how it works is unfortunately not understood. But is is known that it reduces blood flow to the skin, thus reducing the ability for the body to lose heat and increasing body temperature. Similar to Adrenaline (Epinephrine for you North American types) I take it, although a brief search could not link adrenaline to hyperthermia (if you know of anything, please let me know).
What occurs when the temperature regulation mechanism in the brain is disturbed oftentimes when estrogen levels fall during menopause?
It would be hot flashes.
What is the Primary mechanism of homeostatic regulation?
The body's primary mechanism of homeostatic regulation is negative feedback. This mechanism recognizes the problem, identifies the correction, and changes the variable.

What is mechanism of CARP?
The mechanism of CARP is the regulation of the blood glucose, breathing rate, and heart.
What is a example of a homeostasis?
Regulation of body temperature is an example of homeostasis in the human body. When the body is too hot, it sweats to cool down. When the body is too cold, it shivers to generate heat. This process helps maintain a stable internal temperature despite external fluctuations.
If you had a infection in the integumentary system what body system would respond?
The immune system would respond to an infection in the integumentary system. White blood cells would be activated to fight off the infection, and inflammation may occur as part of the body's defense mechanism.
The mechanism of contraction in smooth muscle is different from skeletal muscle in that?
The site of calcium regulation differs
What mechanism is used to finely tune enzyme activity according to the needs of the cell?
allosteric regulation
How is evaporation a cooling process and what are its effects on temperature regulation?
Evaporation is a cooling process because when a liquid evaporates, it absorbs heat from its surroundings, causing a decrease in temperature. This is because the molecules with the highest energy escape from the liquid, leaving behind molecules with lower average kinetic energy, which results in a cooling effect. In terms of temperature regulation, evaporation plays a crucial role in maintaining the body temperature of living organisms. For example, when humans sweat, the sweat evaporates from the skin, taking away heat from the body and helping to cool it down. This is an important mechanism for preventing overheating and regulating body temperature.

Negative feedback is a regulatory mechanism in the body that works to maintain homeostasis by counteracting changes from a set point. For example, in temperature regulation, negative feedback will work to lower body temperature if it rises above the set point. This helps to keep the body systems functioning optimally.
What happens to a thremistat when it gets hot?
When a thermostat detects an increase in temperature, it typically signals the heating system to turn off, helping to maintain a desired temperature range. If it's a cooling system, the thermostat will activate the air conditioning to lower the temperature. In essence, it acts as a control mechanism to ensure that the indoor environment remains comfortable. If the thermostat is malfunctioning, it may not respond correctly to temperature changes, leading to ineffective temperature regulation.
What is the pairing mechanism behind high-temperature superconductivity?
The pairing mechanism behind high-temperature superconductivity is the ability of certain materials to conduct electricity with zero electrical resistance.
