Endocrine System Trivia

1. What is the main function of endocrine glands?

From Quiz Basic Introduction to Endocrine Glands

Answer: To secrete hormones

The endocrine glands secrete hormones which work like chemical signals that control different parts of the body, making those parts work properly, if they receive the right amount of the hormone. When these dosages are not correct, it can cause many problems in the physiology of the body.

From Quiz The Thyroid Gland

Answer: Thyroid cartilage

The thyroid gland is actually named for its position on the thyroid cartilage, which forms the Adam's Apple (also called the laryngeal prominence). The thyroid cartilage in turn gets its name for the Greek for "shield" referring to its shape. The thyroid gland is not shield-shaped at all; it tends to be thought of as butterfly-shaped and wrapping around the cartilage, however when the neck is opened to view the gland, it is rather amorphous. The arytenoid and cricoid cartilages are indeed situated in the larynx, but the costal cartilages are not: they are the small areas of cartilage that join the bony ribs to the sternum.

From Quiz This Gland is Your Gland

Answer: Pancreas

That was an easy starter wasn't it? Before synthetic human insulin and human insulin from genetically modified bacteria was available, most insulin originated from slaughterhouses, thus there were pork insulin and beef insulin.

From Quiz A Lesson In Endocrinology

Answer: ADH

The pituitary gland is divided into two lobes, the anterior lobe (adenohypophysis) and the posterior lobe (neurohypophysis). The neurohypophysis secretes oxytocin and ADH, (antidiuretic hormone). The other three are secreted by the adenohypophysis.

From Quiz Thyroid Physiology

Answer: Auto-immunity

Auto-immunity, in which the immune system mistakes one or more thyroid proteins for foreign proteins, such as those associated with bacteria or viruses, is the main cause of thyroid disease in the US. Auto-immunity can cause the thyroid to be underactive (hypothyroid), or overactive (hyperthyroid). It can cause widespread enlargement resulting in a goiter or regional enlargement leading to thyroid nodules. Iodine deficiency is almost unheard of in the US because most salt is fortified with sodium iodide. Thyroid cancer does occur, but is much less common than breast, lung, or colon cancer, and can be successfully treated in a majority of cases. Radiation exposure can cause thyroid disease, but is also uncommon. In regions downwind from Chernobyl, however, rates of hypothyroidism, and both cancerous and benign thyroid nodules occured at much higher rates than usual for many years after the accident.

From Quiz Blame it on Hormones

Answer: pituitary gland

Prolactin stimulates milk production.

From Quiz The Endocrine System

Answer: endocrinologist

The endocrine system is composed of ductless glands that secrete hormones into the blood.

From Quiz A Guide to the Thyroid

Answer: Low on the front of the neck

The thyroid gland straddles the windpipe at the front of the neck. In men it is positioned just below the Adam's apple. It is a small gland, only about two inches (51 mm) across, but has important functions in the human body.

From Quiz Thyroid Physiology

Answer: The pituitary gland

The pituitary gland monitors circulating levels of thyroid hormones and increases or decreases the amount of TSH, or Thyroid Stimulating Hormone, in order to control the amount of thyroid hormone synthesized and secreted by the thyroid gland.

From Quiz Hormones

Answer: epinephrine

An Epi-Pen is generally used for allergic reactions. It contains epinephrine which helps stop the allergic reaction.

From Quiz Basic Introduction to Endocrine Glands

Answer: The pituitary gland

This gland is located at the base of the brain. The pituitary gland, besides producing the growth hormone, produces other hormones which influence the physiology of many organs. For example, it stimulates the thyroid to produce the hormones which affect metabolism. It stimulates the ovaries to produce estrogen and the testes to produce testosterone. It also stimulates breast tissue to produce milk in mothers. It definitely is the master gland.

From Quiz The Thyroid Gland

Answer: Tongue & Pharynx

I accept "tongue" although technically there is no tongue in the embryo at the time the thyroid gland develops - the gland develops in the pharynx from the foramen caecum, which is a shallow pit seen near the back of the adult tongue. From this foramen, the gland descends into the neck via the thyroglossal duct. This descent can go wrong in various ways - if the thyroid gland does not descend, it develops at the back of the tongue in the adult, giving a lingual thyroid. It can also descend too far into the chest, giving a mediastinal thyroid.

From Quiz A Lesson In Endocrinology

Answer: Thyroid and parathyroid

The thyroid secretes three hormones, one being calcitonin which stores calcium in the bones when the serum levels are too high. The parathyroids secrete a hormone called parathyroxine which does the opposite of calcitonin. Both of these hormones work together to maintain a balance.

From Quiz Thyroid Physiology

Answer: Nucleus

Thyroid hormone receptors are found in the cell nucleus. When thyroid hormone binds to these receptors, they act as promoters or repressors for the expression of a wide range of genes.

From Quiz Blame it on Hormones

Answer: follicle stimulating hormone

FSH is responsible for the maturation of the ovum in females and production of sperm in males.

From Quiz The Endocrine System

Answer: Hypoglycemia

Hyperglycemia is increased glucose in the {blood;} the hypothalamus is an area of the brain that stimulates target organs to secrete {hormones;} homeostasis is the state of having all bodily functions in balance.

From Quiz A Guide to the Thyroid

Answer: To control metabolism

Metabolism is the process of converting food into energy. The hormones produced by the thyroid are vital to produce the energy for all the processes of the body. These include breathing, controlling body temperature, circulation of the blood and digestion. The hormones also contribute to repairing damaged cells. T0, T1 and T2 do exist but are considered to be inert and are described as by-products of the process of creation of the main hormones.

From Quiz Basic Introduction to Endocrine Glands

Answer: The thymus

This gland is located behind the sternum, between the lungs, in the chest cavity. Thymosin is its hormone. The thymus is not only an endocrine gland but is also part of the immune system, where T cells or lymphocytes are produced. These cells protect the body against foreign organisms that could bring disease. According to endocrineweb.com, after puberty, "the thymus starts to slowly shrink and become replaced by fat".

From Quiz The Thyroid Gland

Answer: Tyrosine

Inside the follicles, the thyroid hormones and thyrogloublin together form a solid precipitate called colloid. The thyroid hormones are derived from the amino acid tyrosine and iodide ions - tyrosine is a non-essential amino acid, which means it is not required in the diet, as the body can synthesize it. However, it is important to keep your iodine levels at suitable levels to avoid a lack of thyroid hormones. The thyroid hormones are T3 (or triiodothyronine) and T4 (or tetraiodothyronine, usually called thyroxine). T3 is more potent than thyroxine, so the latter is usually converted to T3 in the body.

From Quiz A Lesson In Endocrinology

Answer: Thymus

The thymus is where T-cells are produced. These cells play a major role in specific immunity. The thymus is most active in younger people and shrinks with age. That is why it is so important to have most of your vaccines when you are young.

From Quiz Hormones

Answer: It stimulates sperm production.

FSH has nothing to do with orgasms in both females and males. Testosterone production is governed by luteinizing hormone.

From Quiz Blame it on Hormones

Answer: oestrogen (estrogen) and progesterone

Oestrogen(estrogen) is responsible for the development of secondary sexual characteristics and the female reproductive system. Progesterone maintains the endometrium (uterus lining).

From Quiz A Guide to the Thyroid

Answer: Iodine

The thyroid needs sufficient quantities of iodine to produce its hormones. In the developed world, most people obtain iodine from a varied diet and iodine is routinely added to table salt in some countries, like the USA although not the UK. Taking iodine supplements is not necessary for most people and can cause more harm than good.

From Quiz Basic Introduction to Endocrine Glands

Answer: Insulin

This gland is the largest of the endocrine glands and it is located behind the stomach. If the pancreas does not produce enough insulin, the result is diabetes, which in the more serious cases, is treated by adding insulin to the body. The pancreas is also part of the digestive system. It excretes pancreatic juice which helps in the process of digestion.

From Quiz The Thyroid Gland

Answer: Calcitonin

Parafollicular cells are also called C cells, which reflects their release of the hormone calcitonin. The cells are located around the follicles in the thyroid tissue. They collaborate with parathyroid glands to move calcium ions around the body. The parathyroid glands are pea-sized glands that are situated at the back of the thyroid gland; they release parathyroid hormone. Parathyroid hormone acts to increase the levels of calcium in the blood by removing it from the gut and bone. Calcitonin keeps the balance by moving calcium back into bone from the blood. It is vital that the balance is kept, because too much calcium can cause tetany (prolonged muscle contraction) which can be life-threatening.

From Quiz A Lesson In Endocrinology

Answer: Polyuria, polydipsia, and polyphagia

Also known as the "three polys". Polyuria is increased urination. A person with excessive sugar in the blood will excrete more water in the urine in order to dilute the urine for easier passage of the sugar. Polydipsia is increased thirst. This is a normal reaction from losing so much water in the urine. Polyphagia is increased hunger. This is caused because the glucose is not being metabolized properly by the cells, therefore the cells feel like they are starving.

From Quiz Hormones

Answer: the pituitary gland

The pituitary gland is the master gland that produces most of your body's hormones, including GH. The thymus gland produces hormones that stimulate the formation of T-Cells. The thyroid gland releases hormones that help regulate heart rate, blood pressure, and body temperature. The adrenal gland releases adrenaline, which is part of the body's "fight or flight" response.

From Quiz Blame it on Hormones

Answer: proteins&peptides&protein&peptide

Hormones maintain homeostasis by changing the activity of cells.

From Quiz Basic Introduction to Endocrine Glands

Answer: Metabolism

The thyroid is located at the base of the neck, between the larynx and the collarbone. It is the size of a thumb and it regulates your weight, your energy level and even your mood. This very small organ is even responsible for regulating your body temperature, for keeping you alert, with normal bowel movements, with a normal appetite, and with a good digestion. The thyroid also works with the pituitary gland (the master gland) because the pituitary gland makes and releases thyroid stimulating hormone (among many others).

From Quiz This Gland is Your Gland

Answer: Sudoriferous glands

It would have been a bit too easy if I had said "sweat glands" but that is what sudoriferous glands are. I'm not so sure that underarm perspiration is generally regarded as particularly sexy and the other glands do not exist.
