Pancreatic Hormones and Glucose Metabolism — Flashcards

Glucagon-like peptide-1 (GLP-1) stimulates _____ secretion and inhibits glucagon secretion

One direct action of growth hormone is _____ glucose uptake into cells, producing an increase in glucose blood concentration

Glucose-insulinotropic peptide causes increased release of _____ in response to an oral glucose load (endocrine effect)

The _____ cells of the islets of Langerhans compose 20% of the islet and secrete glucagon

Does hyperthyroidism present with hypo- or hyperglycemia? _____; Why? Increased gluconeogenesis and glycogenolysis

The zona _____ secretes androgens, such as dehydroepiandrosterone (DHEA) and androstenedione

Prolactin deficiency occurs with destruction of the _____ and results in the failure to lactate (females)

Calcitriol _____ Ca2+ and phosphate release into the bloodstream by stimulating osteoblasts to activate osteoclasts

Chronic exposure of PTH stimulates osteoblasts to express _____, which binds to RANK on osteoclast surfaces to increase activity

Cortisol (glucocorticoids) up-regulates _____ receptors on arterioles, increasing their sensitivity to catecholamines (i.e. norepinephrine and epinephrine)
