Chromaffin cell. Chromaffin cells, also pheochromocytes, are neuroendocrine cells found mostly in the medulla of the adrenal glands (located above the kidneys) in mammals.
The elements sodium (Na) and potassium (K) have been detected in the Moon's atmosphere using Earth-based spectroscopic methods, whereas the isotopes radon -222 and polonium -210 have been inferred from data obtained by the Lunar Prospector alpha particle spectrometer.
The temperature range of the moon is between minus 413 degrees Fahrenheit and 253 degrees Fahrenheit, depending on whether or not the section being measured is facing the sun. Since the moon does not possess a significant amount of atmosphere, its surface cannot trap heat or provide insulation.
