Olfactory Receptors: Location and Structure

9.4K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

Olfaction

44.8K
The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.
The olfactory receptors are embedded in the cilia of the...

Summary

Shark olfactory rosette shape and lamellar count vary significantly among species, not scaling with body size. Diffusible iodine-based contrast-enhanced computed tomography (diceCT) offers a non-destructive alternative for imaging these olfactory organs.

Area of Science:

  • Comparative anatomy
  • Ichthyology
  • Sensory biology

Background:

  • Elasmobranch olfactory rosettes exhibit diverse morphologies, but the functional implications remain unclear.
  • Understanding this diversity is crucial for elasmobranch sensory ecology and evolutionary studies.

Purpose of the Study:

  • To quantify olfactory rosette morphology in elasmobranchs using dissection and diceCT.
  • To analyze trends in rosette morphology within a phylogenetic context.
  • To compare the efficacy of dissection and diceCT for olfactory rosette analysis.

Main Methods:

  • Morphometric analysis of dissected olfactory rosettes from 14 elasmobranch species.
  • Phylogenetic principal component analysis (pPCA) to investigate morphological trends.
  • Diffusible iodine-based contrast-enhanced computed tomography (diceCT) for in situ imaging of olfactory capsules in four Carcharhiniformes species.

Main Results:

  • Significant interspecific variation was found in olfactory rosette fineness ratio and lamellar count, which were positively correlated.
  • The first two principal components of the pPCA explained 82% of the variation, driven by fineness ratio and lamellar count.
  • DiceCT provided comparable results to dissection for rosette structure and volume, validating it as a non-destructive imaging method.

Conclusions:

  • Olfactory rosette morphology in elasmobranchs is species-specific and not directly influenced by body size.
  • DiceCT is a reliable method for in situ analysis of olfactory organ morphology.
  • These findings provide a foundation for future 3D modeling and hydrodynamic studies of elasmobranch olfaction.
