  • 2. 

    Where is the thyroid located in the body?

    • Upper chest under the breastbone

    • Atop the kidneys

    • Posterior to the stomach

    • Below the larynx and partially wrapped around trachea

    Correct Answer
    A. Below the larynx and partially wrapped around trachea
    Explanation
    The thyroid is located below the larynx and partially wrapped around the trachea. This is the correct answer because the thyroid gland is situated in the neck region, specifically in the front of the neck, below the Adam's apple (larynx). It is shaped like a butterfly and consists of two lobes connected by a narrow strip of tissue called the isthmus. The thyroid gland plays a crucial role in regulating metabolism and producing hormones that control various bodily functions.

    The thyroid produces hormones that regulate what bodily function?

    • Blood Production

    • Temperature regulation

    • Cholesterol Production

    • Metabolism

    Correct Answer
    A. Metabolism
    Explanation
    The thyroid produces hormones that regulate metabolism. Metabolism refers to the chemical processes that occur within the body to convert food into energy. The thyroid hormones play a crucial role in controlling the rate at which these processes occur, influencing how quickly or slowly the body uses energy. Therefore, the correct answer is Metabolism.

    Grave’s disease is a form of:

    • Hyperthyroidism

    • Hashimoto's disease

    • Thyroid Cancer

    • Thyroid Nodules

    Correct Answer
    A. Hyperthyroidism
    Explanation
    Grave's disease is a form of hyperthyroidism. Hyperthyroidism is a condition where the thyroid gland produces too much thyroid hormone, leading to an overactive metabolism. Grave's disease is an autoimmune disorder in which the body's immune system mistakenly attacks the thyroid gland, causing it to produce excessive amounts of thyroid hormone. This results in symptoms such as weight loss, rapid heartbeat, irritability, and bulging eyes. Treatment options for Grave's disease include medication, radioactive iodine therapy, and in some cases, surgery.

    Rate this question:

  • 5. 

    Which hormone has the greatest effect on metabolism?

    • Human Growth Hormone

    • Thyroxine

    • TSH

    • ACTH

    Correct Answer
    A. Thyroxine
    Explanation
    Thyroxine, also known as T4, is a hormone produced by the thyroid gland that plays a crucial role in regulating metabolism. It increases the metabolic rate of cells, affecting processes such as energy production and consumption, protein synthesis, and lipid metabolism. Thyroxine stimulates the body's overall metabolic activity, helping to maintain a healthy weight and energy levels. In contrast, human Growth Hormone (hGH), TSH (thyroid-stimulating hormone), and ACTH (adrenocorticotropic hormone) have roles in growth, thyroid function, and adrenal function respectively, but they do not have as significant an impact on overall metabolism as thyroxine does.

    Rate this question:

  • 6. 

    What hormone acts to lower blood calcium levels, and from what cells is it released?

    • Parafollicular hormone/parafollicular cells

    • Thyroxine/follicular cells

    • Parathyroid hormone/parathyroid cells

    • Calcitonin/parafollicular cells

    • ACTH/pituicytes

    Correct Answer
    A. Calcitonin/parafollicular cells
    Explanation
    Calcitonin is the hormone that acts to lower blood calcium levels. It is released from the parafollicular cells in the thyroid gland.

    Rate this question:

  • 7. 

    What is another name for parafollicular cells?

    • "C" cells

    • Parathyroid cells

    • Follicle cells

    • Colloid cells

    Correct Answer
    A. "C" cells
    Explanation
    Parafollicular cells are also known as "C" cells. These cells are found in the thyroid gland and are responsible for producing calcitonin, a hormone that helps regulate calcium levels in the body. The name "C" cells comes from the fact that they are located in between the follicles of the thyroid gland.

    One condition relating to the thyroid is goiter. This is due to a lack of iodine in the diet. Which of the below is affected by a lack of iodine in the diet?

    • T3 and T4

    • Follicle cells

    • Colloid

    • TSH in the pituitary

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    A lack of iodine in the diet can affect all of the options mentioned. T3 and T4 are hormones produced by the thyroid gland, and a deficiency of iodine can lead to reduced production of these hormones. Follicle cells are the cells in the thyroid gland responsible for producing and storing T3 and T4, so they would also be affected. The colloid is a gel-like substance in the thyroid gland that contains the precursor to T3 and T4, and a lack of iodine can disrupt its formation. Finally, TSH (thyroid-stimulating hormone) is produced by the pituitary gland to stimulate the thyroid gland, and a lack of iodine can affect its regulation. Therefore, all of the options are affected by a lack of iodine in the diet.

    Rate this question:

  • 9. 

    Which of the following is NOT a hormone released from the thyroid gland?

    • Triiodothyronine

    • Thyroxine

    • TSH

    • Calcitonin

    • All of the above are released by the thyroid gland

    Correct Answer
    A. TSH
    Explanation
    TSH, or thyroid-stimulating hormone, is not released from the thyroid gland. TSH is actually released from the pituitary gland in the brain and acts on the thyroid gland to stimulate the release of triiodothyronine (T3) and thyroxine (T4), which are hormones produced by the thyroid gland. Calcitonin is also released by the thyroid gland, but TSH is not.

    Hypothyroidism is when your thyroid does not make enough thyroid hormones. It is also called underactive thyroid. Common symptoms include all of the following except: Check all that apply

    • Weight gain, even though you are not eating more food

    • Increased sensitivity to cold

    • Constipation

    • Muscle weakness

    • Rapid Heart beat

    • Depression

    Correct Answer
    A. Rapid Heart beat
    Explanation
    Hypothyroidism is characterized by a decrease in thyroid hormone production, which can lead to a slowing down of bodily functions. Symptoms typically include weight gain, increased sensitivity to cold, constipation, muscle weakness, and depression. However, a rapid heart rate is not a common symptom of hypothyroidism. Instead, it is more commonly associated with hyperthyroidism, which is an overactive thyroid.
