The first cranial nerve associated with the sense of smell, olfaction.
The first cranial nerve which controls the sense of smell.
One of a pair of sensory nerves, the first cranial nerves, that transmit impulses from the mucous membranes of the nasal cavity to the olfactory center in the brain.
The first cranial nerve (I): the special sensory nerve of smell. Fibers of the nerve run upward from smell receptors in the nasal mucosa high in the roof of the nose, through minute holes in the skull, join to form the olfactory tract, and pass back to reach the brain.
The nerves of smell. Each nerve detects smell by means of hair-like receptors positioned in the mucous membrane lining the roof of the nasal cavity.
Either of the first pair of cranial nerves (CN I) supplying the nasal olfactory mucosa. These nerves consist of delicate bundles of unmyelinated fibers (fila olfactoria) that pass through the cribriform plate and terminate in olfactory glomeruli of the olfactory bulb. The fila are central processes of bipolar receptor neurons of the olfactory mucous membrane.
The initial cranial nerve responsible for transmitting sensations of smell as nerve impulses from the nose to the brain. Each of the two olfactory nerves possesses receptors within the mucous membrane that lines the nasal cavity. These receptors detect various smells and convey signals along nerve fibers. These fibers traverse small openings in the roof of the nasal cavity, converging to create the olfactory bulbs. From there, nerve fibers unite to form the olfactory nerve, which leads to the olfactory center within the brain. The sense of smell can be lost or impaired due to damage to the olfactory nerves, often resulting from head injuries.
