Cranial Nerve I
Olfactory nerve
- first of twelve cranial nerves
- supply specialized olfactory receptor neurons in the mucosa of the upper parts of the nasal cavity.
-
- collection of sensory nerve fibers that
- extend from the olfactory epithelium
- to the olfactory bulb
- passes through the many sieve-like openings of the cribriform plate.
- extend from the olfactory epithelium
- collection of sensory nerve fibers that
-
- receptor neurons continue to be born throughout life and extend new axons to the olfactory bulb
- Olfactory ensheathing glia wrap bundles of these axons and are thought to facilitate their passage into the central nervous system.
- supply specialized olfactory receptor neurons in the mucosa of the upper parts of the nasal cavity.
- subserves the sense of smell
- correct name is "olfaction"
- stimulation of receptors by gas molecules from the nose during respiration.
- electrical activity is transduced into the olfactory bulb
- transmits the electrical activity to other parts of the olfactory system and
- central nervous system via the olfactory tract.
- shortest cranial nerves
- one of two that do not join with the brainstem.
- correct name is "olfaction"
