Rostral (anatomical term), situated toward the oral or nasal region; Rostral bone, in ceratopsian dinosaurs; Rostral organ, of certain fish;
Some terms are used more commonly in neuroanatomy, particularly: Rostral and caudal: In animals with linear nervous systems, the term rostral (from the Latin rostrum, meaning "beak") is synonymous with anterior and the term caudal (from the Latin cauda, meaning "tail") is synonymous with posterior.
[25]: 36 When used as an adjective, the term rostral refers to the rostrum. [82]: 357 The rostral and other accessory ossifications attached to the skulls of ceratopsians are collectively termed epiossifications. [54] rostrum The rostrum (plural: rostra) is the snout region of the skull. [82]: 357
Anatomical terms of neuroanatomy [ edit on Wikidata ] The oral pontine reticular nucleus , or rostral pontine reticular nucleus is one of the two components of the medial (efferent/motor) zone of the pontine reticular formation - the other being the caudal pontine reticular nucleus .
The rostral ventromedial medulla (RVM), or ventromedial nucleus of the spinal cord, [1] [2] is a group of neurons located close to the midline on the floor of the medulla oblongata. The rostral ventromedial medulla sends descending inhibitory and excitatory fibers to the dorsal horn spinal cord neurons . [ 3 ]
The primary sensory neurons of these central axons are in the cranial nerve ganglia of each respective cranial nerve. To produce the sense of taste, these neurons project to the gustatory nucleus, or the rostral and lateral regions of the nucleus of the solitary tract, and are ultimately projected to the cerebral cortex.

Standard anatomical terms of location are used to describe unambiguously the anatomy of animals, including humans. 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.
The rostral organ of the coelacanth or similar in many other fish such as Anchovy is a large gel-filled cavity in the snout, with three pairs of canals to the outside. [ 1 ] It is surrounded by an insulating layer of adipose tissue and innervated by the superficial ophthalmic nerve .
