Parts of somatic nervous system Edit. There are 43 segments of nerves in the human body. With each segment, there is a pair of sensory and motor nerves. In the body, 31 segments of nerves are in the spinal cord and 12 are in the brain stem.
In fact, as the Moon travels around the Earth in a counter-clockwise orbit every 27.5 days, it also completes one full rotation on its axis â also moving in a counter-clockwise direction.
The moon rotates slowly, taking 27.3 days to rotate once. This is also exactly how long it takes the moon to orbit Earth. For this reason, observers on Earth can only ever see one side of the moon. Some people have the impression that the moon does not rotate since we always see the same side.
