In cells, structures called Golgi Bodies (also known as Golgi apparatus or Golgi complex) are stacks of membrane-covered sacs that package and move proteins to the outside of the cell.
Pulsus alternans is a physical finding with arterial pulse waveform showing alternating strong and weak beats.
We now know that a pulsar is a rapidly rotating neutron star whose radiation is emitted like a spinning flashlight. Over 700 pulsars have now been detected, with rates of rotation ranging from once every 4 seconds to more than 600 times per second.
