Spinal nerve, ventral and dorsal roots, and ventral and dorsal rami (sing. ramus) all have well-established and widely accepted definitions. Erroneous use only causes confusion. Ventrl roots carry mainly motor fibres (and some sensory fibres, and autonomic fibres at certain levels). Dorsal roots carry sensory fibres. Union of each pair of ventral and dorsal roots forms a spinal nerve. Shortly after the union the spinal nerve divides to form a dorsal ramus (which supplies the skin and muscles of the back of the neck and trunk), and a ventral ramus (which supply the other body parts). Cervical plexus is formed from ventral rami, not ventral roots. Therefore it does not give rise to the greater occipital nerve, which arises from C2 dorsal ramus. - 14 February 2006 137.189.4.1
