Seminar - Endocrine, GI, Urinary, Obstetrics Flashcards
Gland responsible for regulation of the autonomic nervous system and other endocrine glands due to its impact on the pituitary gland.
Hypothalamus
“Master” gland that secretes endorphins which act on the nervous system to reduce sensitivity to pain.
Pituitary gland
Gland that controls ovulation; helps testes and ovaries produce sex hormones.
Pituitary gland
Gland that produces thyroxine and triiodothyronine, which control the rate at which cells burn fuel from food.
Thyroid
Gland that is shaped like a “bow tie” or “butterfly” because it has 2 lobes.
Thyroid
Glands (4) that produce hormones that function to maintain normal levels of blood calcium and phosphate.
Parathyroid glands
Glands that are located on top of each kidney and produce corticosteroids and epinephrine.
Adrenal glands
Structure that includes both endocrine and exocrine tissues; functions to produce glucagon and insulin.
Pancreas
Structures that provide estrogen and progesterone.
Ovaries
Structures that secrete androgens (testosterone) to support sexual development and sperm production.
Testes
Hormone that increases HR and force of contraction; increases energy production.
Epinephrine
Hormone that causes vasoconstriction in skin, viscera, and skeletal muscles.
Norepinephrine
Hormone that increases blood glucose by stimulating conversion of glycogen to glucose.
Glucagon
Hormone that decreases blood glucose and increases the storage of fat, protein, and carbs.
Insulin
Hormone that increases calcium storage in bone and decreases blood calcium levels.
Calcitonin
Hormone that increases uterine contractions and promotes release of milk from mammary glands.
Oxytocin
Hormone that increases water reabsorption; increases BP through stimulating contraction of muscles in small arteries.
Antidiuretic hormone
Condition: excessive secretion of 1+ hormones under pituitary gland’s control (often growth hormone).
Hyperpituitarism
Form of adrenal dysfunction with decreased production of cortisol and aldosterone.
Addison’s Disease
Symptoms include metabolic dysfunction, fluid/electrolyte imbalances, hypotension, weakness, anorexia, weight loss, altered pigmentation, shock, possible death.
Addison’s Disease
Form of adrenal dysfunction with excessive production of cortisol.
Cushing’s Syndrome
Symptoms include persistent hyperglycemia, growth failure, “moon shaped” face, weakness, acne, hypertension, “buffalo hump” at base of neck, mental changes like depression and memory loss.
Cushing’s Syndrome
Decreased levels of thyroid hormones; causes slowed metabolic processes, fatigue, weakness, decreased HR, weight gain, constipation, delayed puberty.
Hypothyroidism (includes Hashimoto’s and underdeveloped thyroid gland).
Excessive levels of thyroid hormones; causes nervousness, increased sweating, weight loss, increased BP, myopathy, exopthalmos, enlarged thyroid gland.
Hyperthyroidism (most specific cause is Grave’s Disease).
