Adrenal glands = Located on the tops of the kidneys, these glands produce steroid hormones such as corticosterone, which helps regulate the body's stress response and maintain homeostasis. Pituitary gland = Is a small bean-shaped gland at the base of the brain. It controls the thyroid gland, adrenal glands, ovaries and testicles by secreting hormones that signal those glands to also produce hormones. Hypothalamus = Is a small gland in the brain located near the pituitary gland. It collects information from virtually all other areas of the central nervous system, and in response it releases hormones that tell the pituitary gland which hormones to send out to other glands. Thyroid gland = is a butterfly-shaped gland located in the neck. It controls the metabolic activity of all cells. Signup and view all the answers

Parathyroid glands = These four small glands are located behind the thyroid, like spots on a butterfly's wings. They monitor and regulate calcium levels. Pancreas = is a long, flat organ that sits just behind the stomach. It produces insulin, which allows muscles and tissues to absorb sugar in the bloodstream, and glucagon, which releases sugars from fat to raise blood sugar levels. Ovaries = They are the primary female reproductive organs, producing reproductive hormones called estrogen and progesterone, and some lesser hormones called relaxin and inhibin. Testes = the male reproductive organs, which are contained in sacs of skin called the scrotum. They produce hormones called androgens, which control the male reproductive system. The most well-known androgen is testosterone. Signup and view all the answers

Pancreas = secretes digestive enzymes called pancreatic juice. Thymus = produces thymosins which Affects production and differentiation of T-cells (lymphocytes) Adrenal glands = makes adrenaline so the body can respond to emergency situations. Hormones = regulate growth, development, mood, tissue function, metabolism, and sexual function. Signup and view all the answers

Goiter = The most common cause of this disease is a lack of iodine in the diet. Hypothyroidism = a common condition where the thyroid doesn't create and release enough thyroid hormone into your bloodstream. This makes your metabolism slow down. Hyperthyroidism, = is a condition where your thyroid makes and releases high levels of thyroid hormone. This condition can make your metabolism speed up. Grave’s Disease = a common cause of Hyperthyroidism, which causes enlargement of the thyroid and other symptoms. Signup and view all the answers

Basedow's disease = occurs when the thyroid gland produces too much thyroid hormone, known as hyperthyroidism Hashimoto’s disease = is an autoimmune disorder that can cause hypothyroidism, or underactive thyroid Myxedema = another term for severely advanced hypothyroidism. It's a condition that occurs when your body doesn't produce enough thyroid hormone. Cretinism = a severe deficiency of thyroid hormone in newborns. It causes impaired neurological function, stunted growth, and physical deformities Signup and view all the answers

Parathyroid Gland Diseases

<h1>Hyperparathyroidism = a condition in which one or more of your parathyroid glands become overactive and release (secrete) too much parathyroid hormone (PTH). Hypoparathyroidism = an uncommon condition in which your body produces abnormally low levels of parathyroid hormone (PTH). PTH is key to regulating and maintaining a balance of two minerals in your body — calcium and phosphorus. Parathyroid cancer = a rare disease in which malignant cells form in the tissues of a parathyroid gland. Signs and symptoms of parathyroid cancer include weakness, feeling tired, and a lump in the neck.</h1> Signup and view all the answers

Pancreas Diseases and Adrenal Gland Disorders

Chronic pancreatitis = inflammation of the pancreas that does not heal or improve. eventually impairs a patient's ability to digest food and make pancreatic hormones. Acute pancreatitis = a condition where the pancreas becomes inflamed (swollen) over a short period of time. Cushing’s syndrome = is a serious condition of an excess of the steroid hormone cortisol in the blood level caused by a pituitary tumor secreting adrenocorticotropic hormone (ACTH). Addison’s disease = also called adrenal insufficiency, is an uncommon disorder that occurs when your body doesn't produce enough of certain hormones. Signup and view all the answers

<h1>Diabetes insipidus = an uncommon disorder that causes an imbalance of fluids in the body. This imbalance leads you to produce large amounts of urine. It also makes you very thirsty even if you have something to drink. Diabetes mellitus = is a disorder in which the body does not produce enough or respond normally to insulin, causing blood sugar (glucose) levels to be abnormally high.</h1> = Signup and view all the answers
