Rostrum (from Latin rostrum, meaning beak) is a term used in anatomy for a number of phylogenetically unrelated structures in different groups of animals.
In mammals, the rostrum is that part of the cranium located in front of the zygomatic arches, where it holds the teeth, palate, and nasal cavity.[6] Additionally, the corpus callosum of the human brain has a nerve tract known as the rostrum.
The beak or snout of a vertebrate may also be referred to as the rostrum.
