- Thyroid cancer blocks the production of this hormone by producing cancer cells in the thyroid glands.
- Anatomically the glands are divided into 2 types - endocrine and exocrine glands.
- The pancreas is a dual-function gland, having features of both endocrine and exocrine glands.
- Thus endocrine glands differ from exocrine glands, in that they lack ducts and deliver their secretions in the bloodstream.

- A doctor first examines the ears, nose, throat (pharynx), voice box (larynx), tonsils, base of the tongue, and thyroid and salivary glands.
- These glands are made up of an inner part called the adrenal medulla and an outer part called the adrenal cortex.
- The Adrenal is actually a combination of two glands the adrenal cortex and the adrenal medulla.
- The endocrine system consists of the pituitary gland, hypothalamus, pancreas, adrenal cortex, thyroid gland, parathyroid glands, and gonads.
- The adrenal cortex, the outer part of each of the two adrenal glands, produces aldosterone, cortisol, and other steroids.
- Aldosterone belongs to a class of hormones called mineralocorticoids, also produced by the adrenal glands.
- Aldosterone – a hormone in the blood made by the adrenal glands that helps regulate sodium and potassium levels.
- As the glands are stimulated, the production of adrenal hormones, and especially cortisone, increases.
- It supports the adrenal glands to increase production of cortisone and other adrenal hormones to help counteract stress and enhance metabolism.
- It stimulates the adrenal glands and increases production of cortisone and other adrenal hormones.
- It can occur as a result of pituitary cancer or some other process that interferes with production of hormones that stimulate the adrenal glands.
- In a few people with acromegaly, tumors in other parts of the body, such as the lungs, pancreas or adrenal glands, cause the disorder.
- The pituitary helps control the release of hormones from other endocrine glands, such as the thyroid and adrenal glands.
- Most patients have an enlargement of all four glands, but some may only have enlargement of one or two glands.
- Rarely there is an adenoma of more than one gland (1%) or there is enlargement of all four glands (3-4%) called hyperplasia.
- The parathyroid glands are four glands in the neck that help control calcium use and removal by the body.
- To help prevent stones from coming back, your doctor may suggest surgery to remove a parathyroid gland or glands (parathyroidectomy).
- Parathyroidectomy is recommended when the parathyroid glands produce excessive amounts of parathyroid hormone (hyperparathyroidism).
- When calcium levels become too high, removal of one or more of the parathyroid glands may be necessary (parathyroidectomy).
- Endocrinologists also receive special training to manage patients with thyroid nodules or thyroid cancer, and enlarged thyroid glands.
- Two adenomas are found less often (approximately 5% of cases) and hyperplasia of all four glands occurs in about 10 to 15% of patients.
- In patients with MEN1, sometimes multiple endocrine glands, such as the parathyroid, the pancreas, and the pituitary become overactive at the same time.

- Sublingual glands: These glands are found under the tongue in the floor of the mouth.
- In addition to these major glands, 600 to 1,000 very tiny, minor salivary glands are scattered throughout the mouth and throat.
- Salivary glands are the parts of the mouth and throat that produce saliva.
- Dry mouth (xerostomia) is caused by a decrease in the amount of saliva in the mouth when the salivary glands do not work properly.
- These glands produce saliva necessary for proper digestion of food, cooling of the body and cleansing of the mouth.
- They thus interfere with the flow of saliva into the mouth, causing the saliva to accumulate in the glands.
- Primary hyperparathyroidism occurs as a malfunction of one of the glands, usually as a result of a benign tumor, called adenoma.
- Other forms of treatment for overactive thyroid glands using either antithyroid drugs or surgery may also result in hypothyroidism.
- Because the parathyroid glands regulate the amount of calcium in the body, their removal will result in low calcium levels.
- Hypoparathyroidism is is an endocrine disorder in which the parathyroid glands in the neck do not produce enough parathyroid hormone (PTH).
- Occasionally, too much parathyroid tissue is removed, and a person may develop hypoparathyroidism (under-functioning of the parathyroid glands).
- Hypoparathyroidism can occur if the parathyroid glands are mistakenly removed or damaged during a total thyroidectomy.
- Other endocrine glands in vertebrates include the thyroid, parathyroids, adrenals, pancreas, and gonads (sex glands).
- The parathyroids are four glands in the neck that produce parathyroid hormone (PTH) to help control calcium use by the body.
- The endocrine glands include the thyroid, parathyroids, anterior and posterior pituitary, pancreas, adrenals, pineal, and gonads.
- This excess occurs due to an enlargement of one or more of the parathyroid glands, or a growth (usually not cancer) on one of the glands.
- The parathyroid glands make a hormone that tells the body how much calcium to store in the bones and how much to have in the blood.
- When the parathyroid glands make too much PTH, a condition called primary hyperparathyroidism exists, causing abnormally high levels of calcium in the blood.
- Swollen "glands," or lymph nodes, refers to enlargement of the lymph nodes in the body.
- Lymph nodes, also known as lymph glands, are small, oval structures found clustered in the neck, armpits, groin, and elsewhere throughout the body.
- The virus invades the spleen, liver and lymph nodes and then moves into other tissues all over the body, including skin and sweat glands.
- Sometimes this is somewhat inaccurately called " swollen glands " (lymph nodes are not glands; they do not secrete anything).
- Symptoms of Streptococcus pyogenes in adults include a fever, sore throat, and swollen glands in the neck.
- The term "swollen glands" refers to enlargement of one or more lymph nodes.
- Hormones are produced by various organs and body tissues, but mainly by the endocrine glands, such as the pituitary, thyroid and gonads (testes and ovaries).
- The gonads are the glands that secrete sex hormones.
- In your case, your sex glands (gonads) are your testes, while in women, their gonads are their ovaries.
- The glands that make up the endocrine system include the thyroid, parathyroid, pancreas, ovaries, testes, adrenal, pituitary and hypothalamus.

- These glands include the hypothalamus, pituitary, pineal, thyroid, parathyroid, thymus, adrenal, pancreas, ovary and testes.
- Breast tissue is made up of milk-producing glands called lobules, ducts that carry milk to the nipples and fat.
- The breast is made up of connective tissue, fat, and breast tissue that contains the glands that can make milk.
- Nipples and glands can occur anywhere along the two milk lines: two roughly-parallel lines along the front of the body.
- These have a variety of functions and include the sweat, sebaceous, salivary, and mammary glands and the glands that secrete digestive enzymes.
- Certain glands of mammals known as mammary glands are specialized to produce milk, a liquid used by newborns as their primary source of nutrition.
- Like all mammals, whales breathe air, are warm-blooded, nurse their young with milk from mammary glands, and have body hair.
- Hyperparathyroidism refers to overactivity and growth of the parathyroid gland or glands.
- Hyperparathyroidism is excessive production of parathyroid hormone (PTH) by the parathyroid glands.
- In hyperparathyroidism one or more parathyroid glands become independent and continue to produce PTH. As a result, the serum calcium climbs.
- Normally, these glands secrete PTH into the bloodstream in response to low blood calcium levels.
- Parathyroid glands produce parathormone (PTH), which controls the metabolism of phosphorus and calcium in the blood.
- The Parathyroid glands produce parathormone or PTH, which raises the level of calcium in the blood.
- Breast cancer starts in the cells lining the ends of the milk-producing glands (the lobules) and in the thin tubes that carry milk to the nipple (the ducts).
- The breast is composed of several glands and ducts that lead to the nipple and the surrounding colored area called the areola.
- Finally, the nipple is surrounded by an area of pigmented skin, the areola, which contains sebaceous glands (which secrete fat) and sweat glands.
- Glands of Montgomery are sebaceous glands in the areola (of the nipple).
- The sebaceous glands are glands found in the skin of mammals.
- F IG. 944 Section of skin, showing the epidermis and dermis; a hair in its follicle; the Arrector pili muscle; sebaceous glands.
- Overactive parathyroid glands produce high levels of parathyroid hormones, which, in turn, results in increased levels of calcium in the blood stream.
- Overactive parathyroid glands produce high levels of parathyroid hormones, which, in turn, results in increased levels of calcium in the bloodstream.
- Underactive parathyroid glands do not produce enough parathyroid hormones.
- With hyperparathyroidism, your glands make too much parathyroid hormone (PTH). This is a chemical that tells the body how to control calcium.
- These glands produce a biochemical called parathyroid hormone, often abbreviated as PTH. When blood calcium drops, PTH is secreted heavily.
- The parathyroid hormone made by these glands increases the calcium level in the blood.
- Because the salivary glands also concentrate iodine, patients may experience swelling of these glands and dry mouth for a time.
- The glands are called salivary glands because of their function.
- Saliva from the salivary glands travels through ducts (passageways) to the mouth.
