Rostrally → It is formed from "rostrum" (from Latin *rostrum*, meaning beak or prow) and the suffix "-ally" (meaning in a manner relating to). The word "rostrally" refers to something that is situated or directed towards the front or beak-like part of an organism or structure.
Think of the word 'rostrum' which means 'beak' or 'front' — so 'rostrally' describes something that is directed towards the front.
