Question

What are the prominent bulges formed caudally between the median sulcus and when the median eminence becomes more prominent on the dorsal surface of the pons?

1) Medial olivary eminence
2) Lateral olivary eminence
3) Substantia nigra
4) Trigeminal motor nucleus

Answer 1

The prominent bulges formed caudally between the median sulcus on the dorsal surface of the pons are known as the Medial Olivary Eminence, connected to the cerebellum via the cerebellar peduncles.

Step-by-step explanation:

The prominent bulges that form caudally between the median sulcus and when the median eminence becomes more prominent on the dorsal surface of the pons are known as the Medial Olivary Eminence. These structures are not part of the substantia nigra or the trigeminal motor nucleus but rather are associated with the cerebellar peduncles. Particularly, they arise from the medulla and are visible as a bulge on the ventral surface of the brainstem, connected to the cerebellum via the cerebellar peduncles.
