(Dexler, in Ellenberger-Baum, .\nat. d. Haustiere.) Fig. 627.—Cauda Equin.!. 1, Dura and arachnoidea divided and reflected; £, spinal cord; 3, nerve-roots. (From Leisering's .\tlas, re- duced.) The surface of the spinal cord is dividetl into two similar halves by a dorsal median groove and a ventral median fissure. On either side of the former is the dorso-lateral groove (Sul- cus dorsalis lateralis), at which the fibers of the dorsal nerve-roots enter the cord; it is faint except at the enlargements, and is represented by two grooves in the first cerv^ical segment. The ventral root-fibers as they emerge from the cord do not form a continuous series, but arise from a zone (Area radicularis ventralis) 3 to 5.
