24 gru 2018 · The olfactory nerve (CN I) is the first and shortest cranial nerve. It is a special visceral afferent nerve, which transmits information relating to smell. Embryologicallly, the olfactory nerve is derived from the olfactory placode (a thickening of the ectoderm layer), which also give rise to the glial cells which support the nerve.
Central Olfactory Pathway. The axons of the olfactory receptor neurons pass through the skull through a tiny series of holes at the cribriform plate. These primary neurons form synaptic connections onto neurons in the olfactory bulb called mitral cells, forming the beginning of the olfactory nerve (CN I).
The olfactory system, or sense of smell, is the sensory system used for olfaction (i.e., smelling). Olfaction is one of the special senses directly associated with specific organs. Most mammals and reptiles have a main olfactory system and an accessory olfactory system.
7 sty 2021 · This article will review the normal anatomy of the olfactory pathways, the CT and MR imaging techniques available to image different components of the olfactory pathway, and highlight the spectrum of olfactory system pathologies.
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.
7 sty 2021 · The olfactory nerves (Cranial Nerve I) and the olfactory pathways connect the peripheral nasal cavity with the central intracranial olfactory system. Olfactory dysfunction can be broadly divided into peripheral conductive and central sensorineural pathologies.
