What is the relationship between spinal and nervous system?

spinal cord and nervous system are related to the fact that the spinal cord together with the brain is part of the central nervous system (CNS). In the CNS, the information raised by the nerve and receptor system throughout the body known as the peripheral nervous system (PNS) is interpreted. CNS also sends PNS signals in response to this information. As the main part of the CNS, the spinal cord adds signals from PNS to the brain and also transmits pulses from the brain to PNS, the pulses that call their feet to step or hand to grab back from the hot surface. Nerve cells known as neurons that perform electrical pulses closed by several layers of protective tissue. These include PIA mater, innermost mening or membranes; Arachnoid mat, middle layer similar to website; and dura mater, thick outer membrane. On the outside of the dura mater in the space between it and surrounding the surrounding, there is an epidural space that contains fat tissues or fat and blood vessels. These pillows of nerve tissue on the bones and give it oxygen and nutrients.

Starting with the base of the brain stem, where it comes from Medully Obrongata, the spinal cord leaves the skull through the opening of the foramen magnum. He then enters the backbone column, a pile of blocking vertebral bones: seven in the cervical area, 12 in the thoracic region, five in the lumbar region and the fused bones with pins in the rear gentleman. The spinal cord passes through the atlas, vertebrae immediately below the skull and a column of bones below it through the hole only the rear of the Each vertebral body known as vertebrae foramen. It continues to the height of the roughly second lumbar vertebra, which ends in Terminale Filum, the narrow length of the nerve tissue that continues through Sacrum and Coccyx.

In each vertebral segment of the spinal cord, it gives a few nerves, a total of 31, which appear on vertebrates to innervate each main tissue and organ in the body. As a spinal cord and a nervous system as the whole function for transmitting information between the body and the brain, these paired nerves bear signals in two directions. Afferent nervesThey do nerve pulses from the body up the spinal cord and towards the brain, while the eperential nerves send information from the brain back down the spinal cord into the body.
