Endocrinology — Flashcards

Vasopressin (ADH) causes _____ of arterioles by activating V1 receptors

PTH action causes increased urinary _____ and phosphat-uria

_____ puberty, excessive levels of growth hormone cause gigantism (increased linear growth)

The _____ cells of the islets of Langerhans compose 65% of the islet and secrete insulin

When insulin acts on adipose tissue, it causes _____ triglyceride storage and decreased lipolysis

Increased ATP:ADP ratio in the pancreatic beta cell (as a result of glucose metabolism) causes ATP-sensitive _____ channels to close, causing membrane depolarization

The main functions of thyroid hormone can be remembered with the "6 B's"?1. _____2. Bone growth3. 1-adrenergic effects 4. Basal metabolic rate (increased) 5. Blood sugar6. Break down lipids

The hormone sensitivity (responsiveness) of a target tissue may be changed in two ways: 1. Change the _____ of receptors 2. Change the affinity of receptors

High levels of _____ inhibit organification of I2, and therefore inhibit synthesis of thyroid hormones (Wolff-Chaikoff effect)

Tissues that are not dependent on insulin for glucose uptake may be remembered using the mnemonic "BRICK LIPS":B: _____R: RBCsI: IntestineC: CorneaK: KidneyL: LiverI: Islet (Beta) cellsP: PlacentaS: Spermatocytes
