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.
Footnotes. 1  The synodic period of the moon, or synodic month, is the orbital period of the moon with respect to the sun. Since lunar phases depend upon the relative positions of the sun, moon, and earth, the synodic month is the period over which the moonâs phases repeat.
