A goitre is a Thyroid Gland, enlarged in an attempt to gather more iodine from the diet. Adding small quantities of iodine to the diet prevents this disorder. the lack of Lithium appears to aggravate the effect.
Paracelsus was a 'scientist' of the 1500s who noted that in Switzerland, (his home country) when both parents had a goitre, the offspring often was an imbecile. Women more commonly suffer this disorder because of child bearing.
[Iodine is the heaviest element needed by the human body]

Why does salt prevent ice from forming on sidewalk?
salt lowers ice's melting point
What would a sink mat be used for?
A sink mat is used to cushion the divider found in common sinks to prevent scratches from forming. It also serves as a cushion in case glassware were to fall.
What are the two temperature scale?
The two most common temperature scales are the Fahrenheit scale and the Celsius scale. However, the Kelvin scale is also used, primarily in science, to prevent negative temperatures.
Why Base Transceiver Station equipments require negative 48 volt DC to function properly why not positive?
it has two reasons.one is to prevent corosion due to the elecrtolitic effect and the other is to protect operator from the line voltage.. it has two reasons.one is to prevent corosion due to the elecrtolitic effect and the other is to protect operator from the line voltage..
How does plastic coating prevent rusting?
Electrolysis can be used to prevent rusting because metals give away electrons and if the metal is wired up to the negative electrode it gains electrons which means it will prevent rusting as it isn't losing electrons.
Is true of feedback?
Negative feedback mechanisms work to prevent sudden severe changes within the body.
The process by which the product of a system shuts down the system or limits its operation is called the inhibition?
The process you are referring to is known as negative feedback regulation. In negative feedback regulation, the product of a system acts to decrease its own production or activity, maintaining a balance within the system. This helps to prevent excessive build-up of the product and maintain stability in the system.
Why negative feedback is essential to a homeostatic system?
Negative feedback in a homeostatic system helps to maintain stability by counteracting changes in the system. It allows the system to sense deviations from the set point and activate mechanisms to bring the system back to optimal functioning. This process helps prevent large fluctuations in the internal environment and maintains a relatively constant internal state.
What kind of negative loops are used to regulate chemical pathways?
Negative feedback loops are commonly used to regulate chemical pathways. In these loops, the end product of a pathway acts as a signal to inhibit further production, helping to maintain homeostasis and prevent overaccumulation of certain substances. This regulation ensures that the pathway operates efficiently and does not waste resources.
What is the importance of negative feedback in the control of vasodilation and vasoconstriction?
Vasoconstriction and Vasodilation are a part of a body negative feedback, in which the body tries to restore homeostasis. Homeostatis is the function of keeping the internal body at it's general temperature (37 degrees Celsius). Without the negative feedback of Vasoconstriction and Vasodilation, the body would either be at a very low or very high temperature and this high/low temperature could cause death.
Why negative feed back desire for amplify aplications?
Negative feedback mechanisms are crucial for amplifying applications because they help maintain stability and prevent runaway effects in systems. By providing corrective responses to deviations from a desired state, negative feedback ensures that processes remain within defined parameters. In applications, this leads to improved accuracy and reliability, as the system can adaptively respond to disturbances, enhancing overall performance. Ultimately, the desire for negative feedback in amplifying applications stems from the need for control and precision in dynamic environments.
How does the negative-feedback mechanism work?
Negative feedback is a regulatory process where the output of a system or process is used to counteract a change in input, maintaining stability. When the output deviates from a set point, it triggers a response that acts to bring the system back into balance. This helps to prevent large fluctuations and maintain a steady state within the system.
What type of homeostasis feedback reflex is the withdrawal reflex?
The withdrawal reflex is a negative feedback reflex that helps the body protect itself from harm. When the body comes into contact with a harmful stimulus, such as touching something hot, the withdrawal reflex causes muscles to contract and move the body part away from the stimulus, which helps to prevent injury.

Why is the negative feedback mechanism control hormonal activity and yet allows hypo and hyper secretion disorders to occur.?
The negative feedback mechanism regulates hormonal activity by inhibiting hormone production when levels are sufficient, maintaining homeostasis. However, this system can be disrupted, leading to hypo or hypersecretion disorders due to factors like receptor insensitivity, gland dysfunction, or external influences. These disruptions prevent the feedback loop from functioning properly, resulting in either insufficient or excessive hormone levels despite the body's regulatory attempts. Thus, while negative feedback aims to stabilize hormonal balance, its failure can lead to hormonal imbalances.
Explain negative feedback and its role?
Negative feedback is a corrective mechanism in biological systems where the response to a stimulus results in the inhibition of that stimulus. It helps to maintain homeostasis by counteracting any deviations from the set point. For example, in the regulation of body temperature, negative feedback helps to prevent overheating or hypothermia by signaling the body to either produce more or less heat.
