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 Moon has no appreciable atmosphere. The sky is always black and the radiation from the Sun strikes with full force on the surface of the Moon. The lack of atmosphere produces temperature extremes on the Moon that range from -250 degrees F in the dark to +250 degrees F in the light.
Like Mercury, the atmospheres of all of these moons are too thin to generate any winds or weather to speak of. The only moon with a fairly thick atmosphere is Saturn's largest satellite Titan. Titan's atmosphere is even denser and produces a greater surface pressure than Earth's.
