The olfactory organs are concerned with the sense of what?
Olfactory nerve via the olfactory tract. The olfactory nerve is the shortest of the twelve cranial nerves and, similar to the optic nerve, does not emanate from the brainstem. The afferent nerve fibers of the olfactory receptor neurons transmit nerve impulses about odors to the central nervous system, where they are perceived by the sense of smell (olfaction). The functional components of the olfactory nerve include the special visceral afferent (SVA), which carries the modality of smell. Damage to this nerve impairs the sense of smell. To simply test the function of the olfactory nerve, each nostril is tested with a pungent
Sensory organs of gastropods gene), which is also important for forming structures for balance in eumetazoans. Mechanoreceptor the mechanoreceptors are very crucial to the snail's sensory. This article incorporates CC-BY-2.0 text from the reference Sensory organs of gastropods The sensory organs of gastropods (snails and slugs) include olfactory organs, eyes, statocysts and mechanoreceptors. Gastropods have no sense of hearing. In terrestrial gastropods the most important sensory organs are the olfactory organs which are located on the tips of the 4 tentacles. In opisthobranch marine gastropods, the chemosensory organs are two protruding structures on top of the head. These are known as rhinophores. An opisthobranch
