Plan of the central and peripheral connections of a spinal nerve: an, afferent (sensory) neurone; asn, afferent sympathetic neurone; ca, cp, anterior (ventral) and posterior (dorsal) columns of grey matter; en, efferent (motor) neurone; esn, efferent sympathetic neurone; grp, dorsal root ganglion; i, intestine (visceral organs); m, skeletal muscle; na, np, anterior (ventral) and posterior (dorsal) rami of spinal nerve; ra, rp, anterior and posterior roots of spinal nerve; rcramuscommunicans (sympathetic) ; sk, skin; sp, white matter of cord; ts, ganglion of sym- pathetic trunk. Slightly modified, from Herrick. The most typical of the structural arrangements of the nervous system may be made out from a study of the connections of any one of the paired nerves of the spinal series (Fig. 36). In the spinal cord the difference in appearance as between the white and the grey matter has already been described (p. 39). A spinal nerve arises by two roots, one of which is dorsal and bears a small ganglion of cellular material, the other ventral and without a.
