Thyroid
The thyroid is responsible for controlling your metabolism, blood calcium levels, energy, excess fats, hormones, oxygen, weight loss. Blood tests can determine your TSH levels to see if you thyroid gland is functioning properly. If you have an under-active thyroid, you are said to have hypothyroidism. If you have an overactive thyroid, you are said to have hyperthyroidism. The thyroid can also be related to several other conditions such as Grave's Disease and heart problems.

Goitrogens are compounds found in certain foods that can interfere with thyroid function by inhibiting the production of thyroid hormones or interfering with iodine uptake. Some examples of goitrogenic foods include broccoli, cauliflower, kale, and soy products. However, cooking these foods can help reduce their goitrogenic effects.
What large molecule is broken down by thyroid cells to produce thyroid hormones?
Thyroglobulin is the large molecule broken down by thyroid cells to produce thyroid hormones. Thyroid peroxidase enzymes help in this process by cleaving thyroglobulin to release thyroid hormones like thyroxine (T4) and triiodothyronine (T3).
What is the function of the hypthalamus and the pituitary gland?
According to Wikipedia, one of the most important functions of the hypothalamus is to link the nervous system to the endocrine system via the pituitary gland. When the thyroid receives thyroid stimulating hormone (TSH) from the pituitary gland it produces triiodothyronine which is commonly referred to as T3, thyroxine which is commonly known as T4, and calcitonin.
The hormonal dysfunction that could cause excessive body hair and a deep voice in women is known as polycystic ovary syndrome (PCOS). PCOS is a common endocrine disorder characterized by hormonal imbalances, particularly high levels of androgens (male hormones), which can lead to hirsutism (excessive hair growth) and changes in vocal pitch. Other symptoms of PCOS may include irregular periods, acne, and weight gain.
What is heterogeneous parenchyma of the thyroid?
Heterogeneous parenchyma of the thyroid means that the basic cellular tissue of the thyroid gland does not have a uniform structure or composition. These can be either benign and/or malignant nodules in the thyroid.
Why excess thyroxine causes hyperthyroidism?
Excess thyroxine in the body, known as hyperthyroidism, can occur due to conditions such as Graves' disease or nodules on the thyroid gland. This excess thyroxine leads to an overactive metabolism, resulting in symptoms like weight loss, rapid heart rate, and nervousness. It can also increase the risk of developing health issues such as heart problems and osteoporosis.
What is the function of the posterior pituitary gland?
The posterior pituitary is made up of axons belonging to cells called neurosecretory cells, whose cell bodies are in the hypothalamus. When these cell bodies are stimulated, the axons in the posterior pituitary releases their hormones into the blood stream. In a way, the posterior pituitary is an extension of the hypothalamus.
Is tetany caused by hyposecretion of the thyroid?
No, tetany is not typically caused by hyposecretion of the thyroid. Tetany is usually associated with low levels of calcium in the blood, which can be caused by factors such as hypoparathyroidism or vitamin D deficiency. Hypothyroidism, on the other hand, results from the underproduction of thyroid hormones by the thyroid gland.
Enlarged thyroid or weight gain may be caused by a prolonged deficiency in?
Iodine. An iodine deficiency can lead to an enlarged thyroid gland (goiter) and weight gain due to an underactive thyroid. Iodine is essential for the production of thyroid hormones, which regulate metabolism and can affect weight.
The major hormone that decreases blood calcium levels is produced in the?
The major hormone that decreases blood calcium levels is produced in the thyroid gland. This hormone is called calcitonin, and it works by inhibiting the breakdown of bone tissue and promoting calcium excretion by the kidneys.
Thyroid vesicles are small sac-like structures within the thyroid gland that store thyroid hormones. These vesicles are lined with cells that secrete hormones into the bloodstream when stimulated by the thyroid-stimulating hormone (TSH) from the pituitary gland.
How do stimulants affect the nervous system in the body?
Stimulants increase activity in the central nervous system. I am assuming that this is in regards to stimulants such as amphetamines, methylphenidates, cocaine, or other types of stimulants.
Stimulants are usually used to treat attention deficit hyperactivity disorder or ADHD. In one way or another they typically affect dopamine and to lesser extent norepinephrine. They also sometimes act on serotonin depending on the stimulant. Stimulants have been the first line of treatment against ADHD there are many controversies over stimulant medications but when taken as prescribed they can be extremely beneficial to individuals that suffer from the disorder. Stimulants used to treat ADHD generally include Adderall, Adderall XR, Dexedrine, Dexedrine Spansules, and forms of methylphenidate or Ritalin as we commonly call it.
Stimulants such as cocaine are not used to treat ADHD. Amphetamines, cocaine and methylphenidate sometimes are abused in order to get high. In one way or another this class of drugs effect dopamine the most, which is a natural reward chemical found in the CNS, norepinephrine is also another neurotransmitter and serotonin. Serotonin is typically linked to depression.
Stimulants are also used performance enhancing drugs at high schools, for the SAT/ACT and, even colleges for undergraduate, graduate, and even doctoral students. They are named "study drugs". As study drug, on what individuals to study for exams over long periods of time. It increases wakefulness and motivation thereby allowing the user to study more and also posses a more motivated mindset on the exams for confidence of their abilities.
What is the job of the pituitary gland and where is it located?
The pituitary gland is known as the "master gland" because it regulates the functions of other endocrine glands in the body by producing and releasing hormones. It is located at the base of the brain, just below the hypothalamus.
What element is used in table salt to control thyroid trouble?
Iodine is the element added to table salt to help prevent thyroid issues. Iodine is necessary for the production of thyroid hormones, which are important for regulating metabolism and other bodily functions. Inadequate iodine intake can lead to thyroid disorders such as goiter.
Does white blood cells have anything to do with thyroid?
White blood cells play a role in the immune response to infections and diseases in the body, including thyroid conditions. In some cases, autoimmune thyroid diseases like Hashimoto's thyroiditis or Graves' disease can involve white blood cells attacking thyroid tissue. These conditions can lead to inflammation and dysfunction of the thyroid gland.
Thyroid follicles are filled with a substance called colloid what is the purpose of colloid?
Colloid in thyroid follicles stores the precursor molecules for thyroid hormones (T3 and T4) which are essential for regulating metabolism, growth and development. It acts as a reservoir from which the thyroid gland can produce and release hormones as needed.
How the endocrine system and nervous system work together when the body is under stress?
During stress, the nervous system activates the "fight or flight" response by releasing hormones like adrenaline. These hormones are produced by the endocrine system and help prepare the body to deal with the stressor. The endocrine system also releases cortisol to help regulate the body's response to stress, working in coordination with the nervous system to maintain homeostasis.
How is digoxin associated with hypokalemia?
Usually, hyperkalemia is associated with usage of digoxin. This is due to the blocking action of digoxin on the Na/K ase which results in accumulation of extracellular K+.
Most of the times, patients presenting with heart problems are already on diuretics before they are prescribed with digoxin. Diuretics cause hypokalemia as they result in excessive excretion of K+ from the body. Hypokalemia in turn causes digoxin toxicity. Digoxin toxicity does not cause hypokalemia, but hypokalemia can worsen digoxin toxicity.
How does endocrine system work or what does it do?
another endocrine glands , the thyroid gland ,secretes a hormone called thyroxine.This regulates the rate of many basic cell activities or metabolism.One way of determining the rate of metabolic activity is by measuring the amount of oxygen that the cells use.

Which hormones are essential for life and why?
Insulin is essential for regulating blood sugar levels, growth hormone is important for growth and development, thyroid hormones regulate metabolism, and cortisol helps the body respond to stress. These hormones play critical roles in maintaining physiological balance and overall health.
What system does the thyroid gland belong to?
The thyroid gland belongs to the endocrine system. It regulates metabolism and produces hormones that affect many functions in the body, including growth and energy levels.
Granola is a high-carbohydrate, whole-grain snack food and breakfast food. Today the ingredients are typically rolled oats, honey or other sweetener, nuts, and perhaps dried fruits. The mixture is stirred while baking, resulting in a fairly loose consistency. The rolled grains are not expanded by absorption of water as when oatmeal is prepared as a hot cereal, so granola is a more concentrated food. It is eaten dry, or in milk or with yogurt, or sprinkled on fruits or other cereals. As it keeps well, many hikers and campers carry it, loose or in the form of granola bars, as an energy food.
What is the purpose of the pituitary gland?
The pituitary gland sends signals to other glands and organs. Like the thyroid gland, adrenal glands, ovaries and testes. It directs them to produce certain hormones. A gland at the base of the brain.

What minerals do estuaries contain?
Estuaries contain an incredible number of minerals which vary in quantity. All the land that is drained by the rivers, creeks, and streams feeding the river that leads to the estuary will contribute to the mineral content. In abundance you would find calcite, feldspars, quartz, clay minerals, mica, iron minerals, salts, elemental metals, hornblende.
