PhysiologyAnswer: 2) Vasoconstriction in most vesselsExplanation: Norepinephrine acts on alpha-adrenergic receptors in the vascular smooth muscles, causing vasoconstriction in most blood vessels. This diverts blood flow to critical organs like the brain and muscles, preparing the body for physical exertion.

General MedicineMembranoproliferative glomerulonephritis is characterized by the deposition of immune complexes in the glomerular basement membrane and mesangium, leading to proliferation of mesangial cells and the formation of a dense, double-contour appearance. This can result in the deposition of fibrin in the glomerulus.
