Summary
This study details the anatomical features of olfactory pathways using cadavers and MRI. Findings provide crucial data for diagnosing olfactory disorders and planning surgeries involving the nasal cavity and anterior cranial fossae.
Area of Science:
- Neuroanatomy
- Medical Imaging
- Ophthalmology
Background:
- Olfactory pathway anatomy is critical for understanding smell disorders.
- Detailed anatomical data is needed for surgical interventions in the nasal cavity and anterior cranial fossae.
Purpose of the Study:
- To provide practical anatomical data for imaging diagnosis of olfactory pathways.
- To aid in surgical operations of the nasal cavity and anterior cranial fossae.
Main Methods:
- Investigated sectional anatomy of olfactory pathways in 17 Chinese adult cadavers.
- Analyzed serial magnetic resonance (MR) imaging of 9 normal adults in transverse, sagittal, and coronal planes.
Main Results:
- Identified olfactory bulb, tract, striae, trigone, anterior perforated substance, and piriform lobe.
- Olfactory bulb and tract located in the olfactory sulcus, overlying the ethmoidal cribriform plate and jugum sphenoidale.
Conclusions:
- Olfactory bulb and tract are closely associated with the ethmoidal cribriform plate and jugum sphenoidale.
- These structures reside within the olfactory cistern, superior to the ethmoid and sphenoid sinuses.

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.

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.

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...
Overview of Somatic Sensory Pathways
Somatic sensory or somatosensory pathways refer to the neural pathways that carry information related to touch, pressure, pain, temperature, and proprioception from the skin, muscles, tendons, and joints to the brain. These pathways involve several stages of processing and integration of sensory information.
The somatosensory system is divided into three main pathways: the dorsal (or posterior) column-medial lemniscus, spinothalamic (or anterolateral), and spinocerebellar pathways.

Major Somatic Sensory Pathways
Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the posterior columns...
Auditory Pathway
Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.
