How does the permissive hormones thyroid hormone and epinephrine work together?
Wikipedia: "In biology, permissiveness is a certain relationship between hormones and the target cell. It can be applied to describe situations in which the presence of one hormone, at a certain concentration, is required in order to allow a second hormone to fully affect the target cell. For example, thyroid hormone increases the number of receptors available for epinephrine at the latter's target cell, thereby increasing epinephrine's effect at that cell. Without the thyroid hormone, epinephrine would have only a weak effect"
What doe sit mean to have an enlarged thyroid?
An enlarged thyroid could mean a number of things. The actual term means that the thyroid gland, which controls most hormones in your body, has been enlarged. This could mean the possibility of thyroid disease, or possibly even thyroid cancer.
Why is the thyroid very important?
The thyroid regulates a number of body functions including how quickly the body uses energy, makes proteins, and controls how sensitive the body should be to other hormones.
What is a overactive thyroid and what happens to you when you have one?
An overactive thyroid may secrete hormones at rapid rates. While this is great for growth and metabolism, overactive thyroids can result in expedited weight loss. This can pose a number of health issues if not controlled or treated in a timely manner.
What element is present in thyroxine?
The thyroid gland or simply, the thyroid, is one of the largest endocrine glands in the body, it is not part of nature, it is part of the human body
The endocrine gland that functions in the greatest number of negative feedback system is labbled?
The endocrine gland that functions in the greatest number of negative feedback systems is the pituitary gland. It regulates various hormones by responding to signals from the hypothalamus and other glands, maintaining homeostasis. This includes controlling thyroid hormones, adrenal hormones, and reproductive hormones, among others. Through these interactions, it plays a central role in the body's feedback mechanisms.
What is the thyroid gland responsible for?
The pituitary gland produces a number of important endocrine hormones. It plays a key part in regulating growth by the production of HGH (Human Hormone). Gigantism is usually caused by pituitary gland tumors which are responsible for the overproduction of HGH.
Is iodine a organism?
Iodine is not an organism, it is an element with atomic number 53. It is used to kill microorganisms which is why it is the main component of Betadine.
The largest number of bound ribosomes most likely would be found in a cell?
The largest number of bound ribosomes would likely be found in cells that are actively synthesizing proteins, such as cells that secrete a large amount of proteins or hormones. These cells would have a high demand for protein production, which requires a significant number of ribosomes attached to the endoplasmic reticulum for protein synthesis.
What does an under active thyroid affect?
An under-active thyroid is a condition in which your thyroid gland doesn't produce enough of certain important hormones. It seldom causes symptoms in the early stages, but, over time, untreated hypothyroidism can cause a number of health problems, such as depression, severe fatigue, obesity, joint pain, infertility and heart disease.
What are the functions of thyroxine and triiodothyronine?
Thyroid hormones T4 (thyroxine) and T3 (triiodothyronine) control the metabolism of all the cells in the body. T4 is known as storage hormone and is the main thyroid hormone produced by the thyroid gland. The 4 indicates the number of iodine molecules attached to it. T4 cannot be used directly by the body until an iodine molecule is dropped and it becomes T3. This is called conversion. T3 is the hormone actually used by cells.
What is a hypothyroidism?
lITERALLY Hypo Thyroid means a smaller, shrunken or less matured thyroid gland. But By Hypothyroidism, we understand 'lesser hormonal activity of the thyroid gland'. The gland even may be far bigger in size, but with less or minimal activity (secretion of hormones)
