The olfactory nerves (I) are special sensory nerves for the sense of smell. They originate in the receptors of the
Where do the olfactory and optic nerves originate from?
The terminal nerves, olfactory nerves (I) and optic nerves (II) emerge from the cerebrum or forebrain, and the remaining ten pairs arise from the brainstem, which is the lower part of the brain. The cranial nerves are considered components of the peripheral nervous system.
How are olfactory nerves formed?
The basal projections of olfactory neurons ascend and traverse the cribriform plate of the ethmoid as unmyelinated axons grouped into small nerve bundles called fila olfactoria. Each of these small nerve bundles forms the olfactory nerves, and there are around 15 to 20 of them on each side of the nasal cavity.
