What's the difference between olfactory and osphradium?
Olfactory
Definition:
(a.) Of, pertaining to, or connected with, the sense of smell; as, the olfactory nerves; the olfactory cells.
(n.) An olfactory organ; also, the sense of smell; -- usually in the plural.
Example Sentences:

(2) Lectin binding and tridimensional reconstruction provided new information on the distribution of olfactory glomeruli and on regional and interspecific differences.
(3) Pathological changes may, thus, be initially confined to projecting and intrinsic neurons localized in cortical and subcortical olfactory structures; arguments are advanced which favor the view that excitotoxic phenomena could be mainly responsible for the overall degenerative picture.

(8) One PCR product hybridized to a 4.0 kb RNA concentrated in subpopulations of putative glutamatergic neurons including mitral cells of the olfactory bulb, pyramidal cells of layer V of the cerebral cortex, pyramidal cells of the piriform cortex, and pyramidal cells of field CA3 of the hippocampus.
(9) Olfactory bulbs are relatively smaller in felids than in canids or viverrids.
(10) A possible role of the olfactory tubercle in olfactory transduction will also be discussed.
(11) Microautoradiography showed that melanin-containing cells in the trunk and head kidney and in the olfactory rosettes also accumulated high amounts of radioactivity.
(12) Examines research in cognitive psychology, which has in the past paid little attention to the olfactory modality.
(13) The staining of HRP-immunopositive cell bodies indicates that the pallial regions studied receive afferent projections from the main olfactory bulb and are reciprocally interconnected by intrapallial associative fiber systems.
(14) The MA and BNST in general are involved in regulation of several sexually dimorphic functions, including aggression, sexual behavior, gonadotropin secretion and integration of olfactory information.
(15) The results also indicate that the two parts of the teleost olfactory bulb are differentiated not only functionally but also morphologically.
(16) Chemosensory cilia of olfactory receptor neurons contain an adenylate cyclase which is stimulated by high concentrations of odorants.
(17) The rhythmic waves induced by these ions were recorded in the olfactory bulb.
(18) Information about olfactory neuron microtubules may be applicable to neurons in general (e.g., the discovery that axons contain microtubules of uniform polarity was first made in the olfactory neuron) or to microtubules in other eukaryotic cells.
(19) Exposure to short photoperiod increased the number of immunoreactive cell bodies within the anterior hypothalamus and preoptic area (AHPOA) and also increased the optical density for staining of immunoreactive cell bodies in the AHPOA and olfactory peduncle.
(20) In younger animals, olfactory receptor cells were observed within the epithelial area isolating the septal organ from the olfactory epithelium, whereas this area was reported to be an exclusive respiratory region in adult rats.
Osphradium
Definition:
(n.) The olfactory organ of some Mollusca. It is connected with the organ of respiration.
Example Sentences:
(1) In preparations containing a portion of the osmoregulatory pathway, the osphradium was stimulated by 90% ASW, and the responsiveness of neuron R15, which putatively regulates antidiuresis, was tested.
(2) Contrary to earlier reports on related ampullariids, the osphradium proved to be ontogenetically older than the mantle and mantle cavity.
(3) The osphradium of the animal is presented as a small torulus formed by supporting ciliated cells.
(4) Most chemosensory neurons are primary sensory neurons, although secondary sensory cells have been reported in the osphradium of some prosobranch gastropods.
(5) Other evidence was from mature adults whose osmoreceptive organ, the osphradium, was lesioned; they mimicked osmoregulation measured in old adults.
(6) The osphradium unites the epithelial canal and the ganglion consisting of two cell populations.
(7) By means of scanning and transmissive electron microscopic methods osphradium of Siphonaria grisea has been studied.
(8) These run to the skin in the mantle area near the pneumostome and osphradium.
(9) In contrast to the model established for A. californica, in A. brasiliana no relationship was found between exposure of the osphradium to dilute media and electrical activity in neuron R15, which is in accordance with the lack of an osmoregulatory mechanism in this species.
(10) Between the epithelial-supporting cells, the putative sensory elements consist of thin neurites (0.4-1.5 micron in diameter) that reach the sea-water side of the osphradium.
(11) The osphradium of Aplysia californica, a sensory organ, is a small yellow-brown epithelial patch located in the mantle cavity immediately anterior to the rostral attachment of the gill.
(12) Ciliary supporting and microvillous cells are described; they do not form any specific for the osphradium zones on its surface.
(13) Perfusion of osphradium of A. brasiliana with dilute seawater (95-80%) did not affect electrical activity of the bursting neuron R15; perfusion with 70 and 60% seawater caused a transient increase in the duration of the quiescent period.
(14) Chemoreceptors are commonly associated with the oral area, the tentacles, and the osphradium, which lies in the mantle cavity.
