Human anatomy, including structure and development and practical considerations . ly directed limbs form the descending endogenous fibres,which, in addition to occupying the boundar\- zone are alsoscattered among the longer tracts of the ground-bundle. Aftera relatively long course, they enter the gray matter to endprobably in relation with the anterior horn cells. They are,therefore, regarded as establishing reflex-paths. Since theseendogenous strands link together various levels of the cord, theyare often collectively termed intersegmental association exogenous tracts of the lateral ground-bundle are closelyrelated with those found in the ground-bundle of the anteriorcolumn and what may be said of the former largely applies tothe latter. Notwithstanding the study that these tracts havereceived, much uncertainty exists as to their exact origin and termination ; it may be stated ina general way, however, that they bring the higher sensory and coordinating centres intorelation with the spinal cord and constitute, therefore, descending paths other than the.
