Endocrinology — Flashcards

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

Amine hormones include _____ hormones and catecholamines (epinephrine, norepinephrine, and dopamine)

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

Insulin increases glucose transport to _____ and adipose tissue by directing the insertion of the GLUT4 transporter into the cell membranes

A testosterone-secreting tumor (or exogenous steroids) presents with _____ testosterone and decreased LH

Estrogens (hormone) cause _____ of the epiphyseal growth plate (bone structure) during puberty.
