The main endocrine glands are the pituitary (anterior and posterior lobes), thyroid, parathyroid, adrenal (cortex and medulla), pancreas, and gonads the parathyroid glands are four masses of tissue, two embedded posteriorly in each lateral mass of the thyroid gland. Men (1 / 2a/ 2b) syndrome commonly includes parathyroid hyperplasia, pituitary adenoma, adrenal adenoma/carcinomas, and pancreatic/islet cell tumors 1 (requires bilateral neck exploration with cervical thymectomy to remove supernumerary glands.

Parathyroid hyperplasia involves enlargement of all four parathyroid glands, which are located in the neck and control calcium metabolism the condition produces high levels of calcium in the blood (hypercalcemia.
Parathyroid this gland is vital to proper bone development because it helps control both calcium and phosphorous levels in the body the parathyroid gland is actually a group of four small glands located behind the thyroid gland. Other endocrine organs include the thyroid, parathyroid, adrenal, and pituitary gland thyroid i gross anatomy the thyroid gland is located dorsolateral to the trachea, close to the larynx it has two lobes that are connected by a narrow isthmus ii histology. Parathyroid adrenals pancreas pituitary multiple endocrine neoplasia (men) carcinoid syndrome pineal gland and melatonin anatomy of the adrenal glands the two adrenal glands (also called the suprarenal glands) are situated in the abdomen, above the kidneys and below the diaphragm. Parathyroid gland four parathyroid glands lie in close association with the thyroid: two embedded in the superior poles and two in the inferior poles on the posterior aspect of the thyroid gland. Parathyroid glands are small endocrine glands in the neck of humans and other tetrapods that produce parathyroid hormone humans usually have four parathyroid glands, variably located on the back of the thyroid gland.
Parathyroid cancer is a rare disease in which malignant (cancer) cells form in the tissues of a parathyroid gland the parathyroid glands are four pea-sized organs found in the neck near the thyroid glandthe parathyroid glands make parathyroid hormone (pth or parathormone) pth helps the body use and store calcium to keep the calcium in the blood at normal levels. Endocrine (thyroid, parathyroid, adrenal) thyroid the thyroid gland is a butterfly shaped organ located in the neck, wrapped around the front of the windpipe, just below the voicebox. The parathyroid glands are tiny, round structures usually found embedded in the posterior surface of the thyroid gland ()a thick connective tissue capsule separates the glands from the thyroid tissue most people have four parathyroid glands, but occasionally there are more in tissues of the neck or chest.
The parathyroid glands in the throat make parathyroid hormone, which regulates the amounts of calcium, phosphorus and magnesium in the bones and blood problems include overactivity (hyperparathyroidism) and underactivity (hypoparathyroidism) depending on the condition, treatment options can. Cancer of the adrenal glands can cause the glands to become larger than normal, causing pain, a feeling of fullness, and weight loss what causes adrenal tumors the cause of adrenal tumors is unknown, and most cases do not have identifiable risk factors. The most common cause of excess hormone production is the development of a benign (non-cancerous) tumor in one of the parathyroid glands this enlargement of one parathyroid gland is called a parathyroid adenoma, and it accounts for 96% of all patients with primary hyperparathyroidism.
Treatment this section will discuss the treatment options for parathyroid conditions overactive parathyroid disease this condition is known as primary hyperparathyroidism, and the only treatment is surgical removal of the abnormal gland about 1 in 600 to 1 in 1000 people have primary hyperparathyroidism.

This chapter covers the thyroid, parathyroid, adrenal, and pituitary glands these endocrine tissues exist as separate glands of course, it is also recognised that many other tissues can secrete hormones and other circulating factors into the blood stream, particularly the pancreas (covered in chap 5 . Adrenocorticotropic hormone reacts with receptor sites in the cortex of the adrenal gland to stimulate the secretion of cortical hormones, particularly cortisol gonadotropic hormones react with receptor sites in the gonads, or ovaries and testes, to regulate the development, growth, and function of these organs.
Adrenal glands are triangular-shaped glands located on top of the kidneys they produce hormones such as estrogen, progesterone, steroids, cortisol, and cortisone, and chemicals such as adrenalin (epinephrine), norepinephrine, and dopamine.
