The axons of the olfactory receptor cells carrying olfactory sensation from olfactory epithelium (1st order sensory neurons) collect to form small bundles(o

From the olfactory mucosa, the nerve (actually many small nerve fascicles) travels up through the cribriform plate of the ethmoid bone to reach the surface of the brain. The pathway of olfactory conduction begins with the olfactory receptors —small, slender nerve cells embedded in large numbers (about 100 million in the rabbit) in the epithelium of the mucous membrane lining the upper part of the nasal cavity. Each olfactory receptor cell emits two processes (projections). OLFACTORY PATHWAYS AND LIMBIC SYSTEM I. OLFACTORY PATHWAYS The sense of smell is much less essential than vision, audition or the somatic senses, and will therefore receive less emphasis in this course. However, since olfactory dysfunction can be an important diagnostic sign, it is important to have at least a rudimentary knowledge of the Olfactory receptor cells – bipolar neurons which consist of two processes: Dendritic process projects to the surface of the epithelium, where they project a number of short cilia, the olfactory hairs, into the mucous membrane. These cilia react to odors in the air and stimulate the olfactory cells. The olfactory nerve originates in the nasal mucosa on the upper part of the nasal cavity as special sensory cells (neurosensory cells of the mucosa), which are the first-order neurons in the olfactory pathway.

1 ): The olfactory receptors are located in the mucosa of the nasal cavities. From there olfactory nerves run to the olfactory bulb which is located inside the bony skull beneath the orbital forebrain. Luktnerven, kranialnerv I (lat. nervus olfactorius) är en av kranialnerverna och består av ett 20-tal små nervtrådar.

Human primary olfactory cortical regions can be parcellated into anatomically distinct areas based on whole-brain functional connectivity profiles, suggesting distinct, parallel functional pathways in the human olfactory system.

Two Parallel Olfactory Pathways for Processing General Odors in a Cockroach. In animals, sensory processing via parallel pathways, including the olfactory system, is a common design. However, the mechanisms that parallel pathways use to encode highly complex and dynamic odor signals remain unclear.

Luktnerven, kranialnerv I (lat. nervus olfactorius) är en av kranialnerverna och består av ett 20-tal små nervtrådar.

BACKGROUND AND PURPOSE: Although the olfactory bulb volume as assessed with MR imaging is known to reflect olfactory function, it is not always measured during olfactory pathway assessments in clinical settings. We aimed to evaluate the utility of visual olfactory bulb atrophy and neuropathy analyses using MR imaging in patients with olfactory dysfunction. MATERIALS AND METHODS: Thirty-four
