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.
But while the Earth rotates in about one day, the Moon takes more than 27 days to rotate, so during one lunar rotation the Sun moves over 27 degrees relative to the stars. To make up for this, the Moon has to rotate more than two days longer, as can be seen by comparing its rotation period to its day length.
