Pyramid of medulla oblongata

Wikipedia, the free encyclopedia - Cite This Source

The interior district of the medulla oblongata is named the pyramid and lies between the anterior median fissure and the antero-lateral sulcus.

Its upper end is slightly constricted, and between it and the pons the fibers of the abducent nerve emerge; a little below the pons it becomes enlarged and prominent, and finally tapers into the anterior funiculus of the medulla spinalis, with which, at first sight, it appears to be directly continuous.
