Summary
Rabbit olfactory mucosa undergoes significant postnatal development, enhancing scent detection for survival. These olfactory adaptations are crucial for young rabbits relying on smell for essential functions like nipple attachment.
Area of Science:
- Developmental Biology
- Neuroscience
- Anatomy
Background:
- Rabbits are born blind and deaf, with limited maternal care.
- Neonatal rabbits depend heavily on olfactory cues for nipple attachment.
Purpose of the Study:
- To investigate the postnatal morphofunctional adaptations of rabbit olfactory mucosa (OM).
- To determine the extent and pattern of OM refinement after birth.
Main Methods:
- Morphologic and morphometric analysis of OM.
- Analysis across neonatal, suckling, weanling, and adult rabbit stages.
- Ki-67 immunostaining to assess cell proliferation.
Main Results:
- Olfactory epithelium cell proliferation decreased with age.
- Axon bundle diameter, olfactory cell density, and cilia number increased with age.
- Cilia projection patterns varied from neonatal tufts to adult radial arrangements.
Conclusions:
- Rabbit olfactory mucosa exhibits significant age-related structural changes.
- These adaptations support the high olfactory demands during postnatal development.
- Enhanced olfactory function is critical for rabbit survival and development.

Olfactory Receptors: Location and Structure
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
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.

Physiology of Smell and Olfactory Pathway
Humans detect odors with the help of specialized cells located in the upper part of the nasal cavity, called olfactory receptor neurons (ORNs). ORNs possess hair-like structures called cilia, which are receptive to sensations from the inhaled air. When an odorant molecule binds to a specific receptor on the cell of the cilia, it leads to a series of events that ultimately cause the ORN to send electrical signals to the olfactory bulb in the brain through the olfactory nerves.
