- Heat generation, metabolic rate, and regulation of many other things are just some of the functions regulated by the thyroid hormones.hyroxine Thyroxine     thyroxine (T4) and triiodothyronine (T3), are tyrosine-based hormones produced by the thyroid gland the thyroid and parathyroid glands are in the neck. the thyroid harmones accelerate the metabolic rate and oxygen consumption in all body tissues.

The Thyroid Gland: Functions, Calcitonin & TSH Video: The Thyroid Gland: Functions, Calcitonin & TSH. Your thyroid gland produces the hormones T3 and thyroxine (T4), which play a role in metabolism. Your thyroid also produces calcitonin, which helps regulate blood calcium levels. In this lesson, you will learn about the thyroid gland and its hormones, including how they are regulated by TSH.

What is hypothyroidism? The production of thyroid hormones is regulated by thyroid-stimulating hormone (TSH), which is made by the pituitary gland and in turn regulated by the hypothalamus. TSH ensures that enough thyroid hormones are made to meet the needs of the body.

How Your Thyroid Works The function of the thyroid gland is to take iodine, found in many foods, and convert it into thyroid hormones: thyroxine (T4) and triiodothyronine (T3). Thyroid cells are the only cells in the body which can absorb iodine. These cells combine iodine and the amino acid tyrosine to make T3 and T4.

- Thyroid hormone (TH) regulates metabolic processes essential for normal growth and development as well as regulating metabolism in the adult (28, 40, 189). It is well established that thyroid hormone status correlates with body weight and energy expenditure (80, 127, 143).

- The primary function of your thyroid gland is to secrete thyroid hormones, which are responsible for controlling your body’s metabolism. The 2 main thyroid hormones are T3 (triiodothyronine) and T4 (thyroxine).The amount of thyroid hormones secreted is controlled by another hormone, called thyroid stimulating hormone (TSH), which is released from the pituitary gland in your head.alcitonin. Another hormone that’s produced in your thyroid gland is called calcitonin. This hormone, secreted by a small population of cells known as C cells, is involved in regulating the level of calcium in your blood.

Thyroxine Thyroxine is the name of the hormone secreted by thyroid gland which does the work of metabolic activities. It also controls the rate of oxidation level in the cells. Thyroxine hormone contains 65% iodine which is necessary for the production of T3 and T4 (tyrosine) hormones.hyroxine is the name of the hormone secreted by thyroid gland which does the work of metabolic activities.

Thyroid Hormone Regulation - Negative Feedback Loop [Hypothalamus and Anterior Pitutiary] The hypothalamus secretes thyrotropin-releasing hormone which, in turn, stimulates the pituitary gland to produce thyroid stimulating hormone. This hormone stimulates the production of the thyroid hormones, thyroxine and triiodothyronine, by the thyroid gland. This hormone production system is regulated by a negative feedback loop so that when the levels of the thyroid hormones, thyroxine and triiodothyronine increase, they prevent the release of both thyrotropin-releasing hormone and thyroid stimulating hormone.

Thyroid Gland Overview The thyroid keeps your metabolism under control through the action of thyroid hormone, which it makes by extracting iodine from the blood and incorporating it into thyroid hormones. Thyroid cells are unique in that they are highly specialized to absorb and use iodine.

What is the thyroid and what does it do? Once released from the thyroid gland into the blood, a large amount of T4 is converted to T3 -- the active hormone that affects the metabolism of cells throughout the body. Thyroid hormone regulation -- the chain of command. The thyroid itself is regulated by another gland located in the brain, called the pituitary. In turn, the pituitary is regulated in part by the thyroid (via a feedback effect of thyroid hormone on the pituitary gland) and by another gland called the hypothalamus.

Human Physiology/The endocrine system The Production of T3 and T4 are regulated by thyroid stimulating hormone (TSH), released by the pituitary gland. TSH Production is increased when T3 and T4 levels are too low. The thyroid hormones are released throughout the body to direct the body's metabolism.

- Thyroid hormones control metabolism, growth, body temperature, muscle strength, appetite, and the health of your heart, brain, kidneys, and reproductive system. Thyroid cells are the only cells in the body that absorb iodine.hen things go wrong. Thyroid disease occurs when your thyroid under-or over-produces the correct amount of thyroid hormone. It can cause elevated cholesterol levels, heart disease, infertility, muscle weakness, osteoporosis, coma, and even death.

- Thyroid hormones produce effects by docking with protein receptors in thyroid-sensitive tissues. The hormones can bind with receptors on the cell's membrane surface and inside the cell on the mitochondria or in the nucleus.

Homeostasis and Regulation in the Human Body The endocrine system regulates the metabolism and development of most body cells and body systems through feedback mechanisms. For example, Thyrotropin-Releasing Hormone (TRH) and Thyroid Stimulating Hormone (TSH) are controlled by a number of negative feedback mechanisms.

Thyroid Gland As a component of the endocrine system, the thyroid secretes hormones that control important functions including metabolism, growth, heart rate, and body temperature. Found within thyroid tissue are structures known as parathyroid glands.arathyroid glands contain many cells that secrete hormones and have access to extensive blood capillary systems. Parathyroid glands produce and secrete parathyroid hormone. This hormone helps to regulate calcium concentrations by increasing blood calcium levels when these levels dip below normal.

Structure and Function: Thyroid and Parathyroid Glands The thyroid and parathyroid glands are situated close to each other in the front of the neck. The thyroid gland produces the hormone thyroxine (T 4) and its more active form, T 3, which act on body cells to regulate metabolism (the chemical reactions continually occurring in the body).Some thyroid cells secrete the hormone calcitonin, which lowers calcium in the blood.hyroid and parathyroid hormones. Iodine from the diet is used to make the hormones T 4 and T 3. These hormones are produced by the thyroid gland and regulate body metabolism. Parathyroid hormone (PTH) and, to a lesser extent, calcitonin regulate levels of calcium and phosphate.

- The thyroid hormones, triiodothyronine (T3) and its prohormone, thyroxine (T4), are tyrosine-based hormones produced by the thyroid gland that are primarily responsible for regulation of metabolism. Iodine is necessary for the production of T 3 and T 4.hyroid hormones (T 4 and T 3) are produced by the follicular cells of the thyroid gland and are regulated by TSH made by the thyrotropes of the anterior pituitary gland. The effects of T 4 in vivo are mediated via T 3 (T 4 is converted to T 3 in target tissues). T 3 is 3- to 5- fold more active than T 4.

- The hormones secreted by the thyroid gland are the triiodothyronine (T3), thyroxine (T4) and the thyrocalcitonin which is responsible for the calcium reabsorption or breakdown. T3 and T4 are the two primary hormones responsible for metabolism. The anterior pituitary gland signals the thyroid gland to secrete hormones.s I have said earlier, the thyroid gland is responsible for the regulation of the metabolism of the body. This means that the thyroid secretes hormones that are responsible for burning the calories, fats and other nutrients used by our body for energy.
