ANSWERS AND EXPLANATIONS

---

A) Neonatal cerebellum

This answer is correct.

This slide shows neonatal cerebellum. Note the presence of the external granular cell layer (EGCL), which is indicated by the unnecessarily large red arrow in the image above. Cells from the EGCL migrate inward, to form the granule cell layer. The EGCL is seen in fetal and neonatal cerebellum.
