The papillary muscles anchor the chordae tendineae that hold the atrioventricular valves shut against ventricular pressure

Because the central and peripheral oxytocin systems are largely separate

the iconic circular structure that has been the working object of molecular biology ever since

with a receptor-binding domain at its tip

so a dose that clears in a few hours for a person can take more than a day in a dog and accumulate to toxic levels

Feynman scattering necklace | gold vermeil MnM The papillary muscles anchor theFeynman scattering necklace gold vermeil A Feynman diagram on a chain, in 18K gold vermeil. The geometry is the simplest possible electron photon interaction: two incoming particles, an exchange, two outgoing particles. The diagram is the calculation, not just a drawing of it. The pendant carries that idea at 34 mm. The Science Behind the Scattering Diagram Richard Feynman introduced his diagrammatic notation for quantum electrodynamics in the late
