Thyroidism Lab Report

The thyroid is a butterfly-shaped gland. You would find it located in the lower neck, right below the Adam’s apple. The location is the same in both men and women. What the thyroid does is create and store thyroid hormone. It then releases the hormone in appropriate amounts to keep the body’s metabolism functioning at a normal level. If there is too much thyroid hormone, this is known as hyperthyroidism. In hyperthyroidism, the body’s metabolism increases. This condition can cause high blood pressure, high heart rate, nervousness, palpitations, and severe weight loss. Too little thyroid hormone, on the other hand, can cause tiredness, depression, memory loss, dry skin, brittle hair, and weight gain—among many other symptoms.

The thyroid is a small gland that rests in the lower neck. It is in charge of controlling the body’s metabolism by producing hormones (such as T3 and T4) that tell the body’s cells how much energy to use (2). The pituitary gland is in charge of monitoring the quantity of thyroid hormones in the bloodstream (2).

Thyrotoxicosis is a clinical condition caused by excess circulating serum thyroxine (T4), triiodothyronine (T3), or both with suppression of thyroid-stimulating hormone (TSH). A negative feedback loop involving the hypothalamus, pituitary, and thyroid gland regulates the production and release of thyroid hormones. (Fig. 1) The hypothalamus releases thyroid-releasing hormone (TRH), stimulating the pituitary gland to release TSH, in turn stimulating the thyroid gland to release T4 and T3. Enhanced production of T4 and T3

The thyroid gland is the gland that makes and stores hormones that help regulate the heart rate, blood pressure, body temperature, and metabolism. Thyroid hormones are essential for the function of every cell in the body. They help regulate growth and the rate of chemical reactions in the body. Thyroid hormones also help children grow and develop. The thyroid gland is located in the lower part of the neck, below the Adam's apple, wrapped around the trachea. It has the shape of a butterfly with two lobes attached to one another by a middle part called the isthmus. The thyroid uses iodine, a mineral found in some foods and in iodized salt, to make its hormones. The two most important thyroid hormones are thyroxine (T4) and triiodothyronine

Thyroid hormone production is regulated by a hormone called thyroid stimulating hormone and it is made in the brain by the pituitary gland. Since it occurs in the thyroid gland, thyroid hormones affect metabolism, brain development, body temperature, skin dryness, and it speeds up many of the body’s functions. The

The thyroid is a small butterfly shaped gland in the front of the neck. It makes hormones called T3 and T4. They regulate how the body uses energy. Thyroid hormone levels are controlled by the pituitary, which is a pea-sized gland in the brain. It makes thyroid stimulating hormone (TSH), which triggers the thyroid to make thyroid hormone.

This is because the thyroid is unable to perform its’ normal functions, such as cellular metabolism. Lethargy results in response to “slowing of cellular metabolism” (Kahn, 2010). Compared the normal thyroid, “about half the increase in oxygen consumption produced by the thyroid hormones is related to activation of the plasma-membrane-bound Na/K ATPase… Changes are linked directly to calorgenic effect of thyroid hormones” (Kahn, 2010). If less oxygen is getting to the cells, this can begin to cause anaerobic respiration and will cause a decrease in energy and become stiff. “The muscles will appear pale and swollen. The fibers may show swelling, loss of normal striations, and separation by mucinous deposits. Type 1 muscle fibers tend to be predominate” (Melmed, 2011). Also, if the thyroid is unable to metabolize lipids and absorb carbohydrates, this will cause decreased energy production. The decrease in energy is what causes humans to feel fatigue or lethargic, which is indirectly caused by the corrupted metabolism of lipids and breakdown of

In a normally functioning body, Thyroxine (T4) and Triiodothyronine (T3) are hormones produced by the thyroid gland. They help control the rate at which the body uses energy and are regulated by a feedback system. Thyrotropin or Thyroid-Stimulating Hormone (TSH) from the pituitary gland stimulates the production and release of T4 (primarily) and T3 by the thyroid. Most of the T4 and T3 circulates, bound to protein, in the blood. A small percentage is free (not bound).

Even though Cardiovascular signs of hyperthyroidism include tachycardia, widened pulse pressure, marked increases in cardiac output, and respiratory capacity. Hyperthyroidism induces a hyper-dynamic cardiovascular state, which manifests by a faster heart rate, higher systolic and diastolic function. Various changes in the coagulation-fibrinolytic system have been described in patients with an excess or deficiency of thyroid hormones. Abnormalities of erythrocytes, leucocytes, thrombocytes and coagulation too much hormone induces anxiety and nervousness.

The body’s metabolism speed, which can be controlled mainly from the thyroid gland is affected by it.

The thyroid gland is located in the lower front part of your neck. In this gland, hormones are release that travel through the bloodstream which affect almost every part of the body all the way from the heart, brain and muscles to the skin. Hypothyroidism and hyperthyroidism are two diseases associated with the thyroid. These two diseases are both related to the thyroid but affect the body in different ways.

Hypothyroidism happens when there is underproduction of the hormone thyroxin. The thyroid gland does not produce enough for what the body needs.

Many may wonder what the thyroid is; as per Merriam-Webster’s dictionary the thyroid is “a gland at the base of the neck that produces hormones which affect growth, development, and the rate at which the body uses energy”. (“Thyroid.” Merriam-Webster) In other words a gland that helps in producing hormones to

The thyroid is an endocrine gland located at the base of the neck. It produces thyroid hormones which effect the bodies metabolic rate and protein synthesis. The thyroid hormones include triiodothyronine and thyroxine which are made from iodine and tyrosine. These hormones are controlled by thyroid-stimulating hormone which is secreted by the anterior pituitary gland at the base of the brain. When these hormones are produced in an insufficient amount hyperthyroidism occurs. Hypothyroidism can be subdivided into two classes; primary disease which affects the thyroid gland itself or central disease which results from dysfunction of the pituitary or hypothalamus. The causes of hypothyroidism include autoimmune thyroiditis, radioiodine ablation,

A thyroid is a butterfly shaped gland in the front of the neck. The thyroid gland makes hormones that control the speed of our metabolism. They may slow down or speed up your metabolism by disrupting the process that the thyroid gland does. A difference in weight is a common sign of having thyroid disease. When the thyroid hormones are low you gain weight (Hypothyroidism), when the thyroid hormones are high you lose weight (Hyperthyroidism). A really common type of weight loss is when you lose weight. When you have swelling or enlargement
