Rostral (anatomical Term)
Standard anatomical terms of location are used to describe unambiguously the anatomy of humans and other animals. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and axes. The meaning of terms that are used can change depending on whether a vertebrate is a biped or a quadruped, due to the difference in the neuraxis, or if an invertebrate is a non-bilaterian. A non-bilaterian has no anterior or posterior surface for example but can still have a descriptor used such as proximal or distal in relation to a body part that is nearest to, or furthest from its middle. International organisations have determined vocabularies that are often used as standards for subdisciplines of anatomy. For example, '' Terminolo ...

Rostral Bone
Ceratopsia or Ceratopia ( or ; Ancient Greek, Greek: "horned faces") is a group of herbivore, herbivorous, beaked dinosaurs that thrived in what are now North America, Asia and Europe, during the Cretaceous Period (geology), Period, although ancestral forms lived earlier, in the Late Jurassic of Asia. The earliest known ceratopsian, ''Yinlong downsi'', lived between 161.2 and 155.7 million years ago.Holtz, Thomas R. Jr. (2011) ''Dinosaurs: The Most Complete, Up-to-Date Encyclopedia for Dinosaur Lovers of All Ages,'Winter 2010 Appendix./ref> The last ceratopsian species, ''Triceratops prorsus'', became extinct during the Cretaceous–Paleogene extinction event, . ''Triceratops'' is by far the best-known ceratopsian to the general public. It is traditional for ceratopsian genus names to end in "''-ceratops''", although this is not always the case. One of the first named genera was ''Ceratops'' itself, which lent its name to the group, although it is considered a ''nomen dubium'' tod ...

Rostral Organ
The rostral organ of the coelacanth or other fish is a large gel-filled cavity in the snout, with three pairs of canals to the outside. It is surrounded by an insulating layer of adipose tissue and innervated by the superficial ophthalmic nerve The ophthalmic nerve (CN V1) is a sensory nerve of the head. It is one of three divisions of the trigeminal nerve (CN V), a cranial nerve. It has three major branches which provide sensory innervation to the eye, and the skin of the upper face .... Its anatomy and innervation suggest it is an electroreceptive organ used for finding prey in the dark. This is supported by experiments which showed that coelacanths react to electrical fields produced by a submersible. References Sensory organs in animals Fish anatomy {{Vertebrate anatomy-stub ...

Rostral Scale
The rostral scale, or rostral, in snakes and other scaled reptiles is the median plate on the tip of the snout that borders the mouth opening. Wright AH, Wright AA (1957). ''Handbook of Snakes of the United States and Canada''. Ithaca and London: Comstock Publishing Associates. (7th printing, 1985). 1,105 pp. (in two volumes). . It corresponds to the mental scale in the lower jaw. The term pertains to the rostrum, or nose. In snakes, the shape and size of this scale is one of many characteristics used to differentiate species from one another.

Rostral Column
A rostral column is a type of victory column originating in ancient Greece and Rome, where they were erected to commemorate a naval military victory. Its defining characteristic is the integrated prows or Naval ram, rams of ships, representing captured or destroyed enemy ships. The name derives from the Latin Rostrum (ship), ''rostrum'' meaning the bow of a naval vessel. Rostral columns of the modern world include the Columbus Monument (New York City), Columbus Monument at Columbus Circle in New York City, and the paired Old Saint Petersburg Stock Exchange and Rostral Columns, Saint Petersburg Rostral Columns. List of notable rostral columns Ancient * Columna Rostrata C. Duilii ("Rostral Column of Gaius Duilius"), celebrating the naval Battle of Mylae (260 BC); formerly in the Roman Forum, some remnants of the inscription are now in the Capitoline Museum. Modern * the Grenville Column, monument to Thomas Grenville (Royal Navy officer), Royal Navy officer Thomas Grenville ...
