On the ventral surface of the medulla, which structures are visible?

Explanation:
Recognizing what appears on the ventral surface of the medulla comes down to identifying its motor-pathway landmarks. The central midline bulge is the pyramids, formed by descending corticospinal and corticobulbar tracts. Lateral to each pyramid lies the olive, a rounded prominence from the inferior olivary nucleus. These features are classic for the ventral medulla and reflect major motor pathways and their nuclei. Mammillary bodies, hippocampus, and olfactory bulbs reside in other parts of the brain (hypothalamic/limbic regions and the frontal-temporal areas), not on the ventral medulla, so they are not seen there.
