increased height tlie posterior median sulcus of the cord becomes deepened into the 

 posterior median fissure. The posterior intermediate sulrus is also accentuated 

 by Burdarh's column, likewise enlarged into the funiculus cuneatus of the medulla. 

 The lateral funiculus of the medulla, of course, does not contain the lateral or crossed 

 pyramidal tract present in the spinal cord. 



At the lionler of the calamus script orius the funiculus gracilis terminates in a slight 

 elevation, the clava, which is the superficial indication of the nucleus funiculi gracitis.

somewhat more anteriorly, and having a somewhat greater length, is a 

 similar enlargement of the funiculus runeatus. the tuberculum cuneatum or 

 nucleus funiculi cuneati. These nuclei arc the groups of nerve cell-bodies about 

 which the ascending or sensory axones of the respective funiculi terminate or are 

 interrupted in their course to the structures of the encephalon. These cell-bodies 

 in their turn give off axones which immediately cross the mid-line and assume a 

 more ventral position, contributing largely to the lemniscus or fillet of the opposite
