Spinal Nerves

There are 31 pairs of spinal nerves. These branch out from the spinal cord, dividing and
subdividing to form a network connecting the spinal cord to every part of the body. The
spinal nerves carry information from receptors around the body to the spinal cord. From
here the information passes to the brain for processing. Spinal nerves also transmit motor
information from the brain to the body’s muscles and glands so that the brain’s
instructions can be carried out swiftly. Each of the 31 pairs of spinal nerves belongs to
one of the four spinal regions— cervical, thoracic, lumbar, and sacral. Of them, the
cervical region has eight pairs, the thoracic has twelve pairs, the lumbar has five, and
finally, the sacral has six pairs.
