he superior part of the filurn terminale internum some bundles of medullated 

 erve-fibres are observed clinging to its sides, and with these are associated some

SUMMARY OF THE CHIEF CHARACTERS PRESENTED BY THE SPINAL MEDULLA 

 IN ITS DIFFERENT REGIONS. 



COMPONENT PARTS OF THE GRAY MATTER OF THE SPINAL MEDULLA. 



Neuroglia enters largely into the constitution of the gray matter of the spinal 



medulla. It forms a bed within which the nervous elements are distributed. 



tese nervous elements consist of (1) nerve -cells and (2) nerve -fibres both 



medullated and non - medullated. The nerve -cells lie in small spaces in the
