Visualization of Pathways
The
various pathway systems cannot be identified on normal transverse sections of
the spinal cord. Only under special circum-stances (in experimental
transection, in spi-nal cord injury, or during development when tracts become myelinated at different times), can
they be distinguished from each sother, such as the late myelinating pyra-midal
tract (D2). In case of injuries, distal fibers separated
from the perikaryon degenerate so that their area in the spinal cord becomes
visible, such as the fasciculus gracilis (E13).
