Olfactory Nerve Pathway Flowchart

The odor information originates in the epithelium of the nasal cavity and is transported to the brain via components of the olfactory nerve cranial nerve 1 cni and the olfactory pathway.

Olfactory nerve pathway flowchart. The axons of the olfactory neurons extend from the basal surface of the epithelium through an olfactory foramen in the cribriform plate of the ethmoid bone and into the olfactory bulb located on the ventral surface of the frontal lobe. This nerve is made of many small nerve fibers called fascicles that are bound together by thin strips of connective tissue. Nervous pathways of smell. In this article we shall look at the anatomy of the.

Olfactory epithelium components 3 1olfactory cells bipolar neurons in the upper posterior nasal cavity with cilia and specific proteins to detect odorants. It was reported that the intranasally administrated 3 kda fluorescein dextran was transferred in the connective tissue surrounding the olfactory nerve bundles to the olfactory bulb within 15 min jansson and bjork 2002. Gottfried et al 2004. 31 olfactory nerve pathways.

It originates in the olfactory mucosa mucous membrane along the roof of your nasal cavity nostril. Ninja nerds join us in this video where we discuss the olfactory nerve cranial nerve i. The afferent nerve fibers of the olfactory receptor neurons transmit nerve impulses about odors to the central nervous system derived from the embryonic nasal placode the olfactory nerve is somewhat unusual among cranial nerves because it. We go into great detail on the origin course and structures supp.

The pathway of olfactory conduction begins with the olfactory receptorssmall 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. The olfactory nerve is the shortest nerve in the human head. Gottfried et al 2006. Gottfried et al 2002.

Olfactory epithelium olfactory bulbs olfactory striae. Olfactory nerve pathways are considered as a major component of nose to brain delivery. It is a special visceral afferent nerve which transmits information relating to smell. The olfactory nerve cn i is the first and shortest cranial nerve.

Kauer 1991 but the distinct roles of these primary olfactory areas and their functional pathways are not fully understood bensafi et al 2007. One of these is a short peripheral dendrite which reaches. Each olfactory receptor cell emits two processes projections. The fact that the olfactory bulb simultaneously projects directly to a number of structures suggests parallel functional pathways in the olfactory system haberly 2001.

The olfactory nerve is typically considered the first cranial nerve or simply cn i that contains sensory nerve fibers relating to the sense of smell.
