Abstract

The distribution of the spinal branches to the developing spinal cord in dogs from 7-25 cm CVR length was examined in injected and non-injected specimens. This study revealed that the grey mater is richly supplied than the white mater, also the segments of the spinal cord entering into the formation of the Intumescentiae cervicalis and lumbalis are richly vascularized in comparison to the segments other than those of the enlarg ments.
The spinal branches forming the angioarchitecture of the spinal cord are arranged at first in three groups which correspond to the dorsal, inter mediate and ventral grey horns of the cord. This study pointed also to the vasculature of the spinal ganglia.
