centrum

Impotentia psychica ea est quae ex coercitatione inhibente cerebri in centrum genito-spinale exercitata devenit.

Its body, the pars perpendicularis (mesethmoid) shows no similarity with a vertebral centrum.

These fibre constitute by far the greater part of the white centrum oval of the hemisphere.

A similar pair of processes arising from the ventral surface of the centrum form the ventral or haemal arch.

Each centrum is a short cylinder of cartilage surrounding an hourglass-shaped cavity occupied by the notochord.
