There are actually 12 pairs of cranial nerves which arise in the brain, and 31 pairs of spinal nerves which increase with the spinal twine. Cranial nerves are named I to XII, determined by their cranium exit site (anterior to posterior). Spinal nerves are divided into eight cervical, twelve thoracic, 5 lumbar, five sacral and 1 coccygeal nerve, based upon vertebral level from which they crop up. In selected parts of the body peripheral nerves interconnect, developing neural networks known as plexuses. Notable plexuses are the:
connective tissues, which might be made up of broadly spaced cells and huge amounts of intercellular matrix and which bind jointly several body structures
A sagittal airplane that does not divide the body into equal remaining and proper halves (also longitudinal part).
