Olfactory tracts
Sensory neuron
The Olfactory bulb via the olfactory nerves in the nose.
The olfactory bulb is a small , match-head sized organ in the top of the nasal cavity,and is connected to hundreds of olfactory hairs, or cilia, which lie in a layer of mucous. These have receptor sites, and it is still not well understood how these work, but one theory is that the shape of the molecule (of the substance being smelt) and the way in which it locks onto the receptor determines the impulses sent to the brain. (the bulb is thought of as a direct extension of the brain) If this is true, it may help explain why with prolonged exposure to a smell, you will stop smelling it until you go outside and clear the nose and come back.The receptor sites become saturated with the molcules and stop sending nerve impulses.
The olfactory nerves' main function is to transmit impulses fron our nose to the brain. It is these nerves that help us to identify smell.
No. The ears and eyes work together to produce equilibrium, not the nose.
The smell receptors are called olfactory nerves
So, we just learned this in anatomy. You breathe in an odogen. The odogen binds with protein receptors in the olfcatory cilium. A potential travels on an axon the olfactory receptor cells synapsing in the olfactory bulb. Then the filaments of the olfactory nerve synapses with mitral cells causing impulses to flow from the olfactory bulbvia the olfactory tracts.
The olfactory nerves are cranial nerves( arise from the brain ). olfactory nerve is the first nerve among the all cranial nerves. olfactory nerves passes sense of smell through nerve impulses( chemical=neurotransmitters, and electrical signals ).
The olfactory nerve, also known as the first cranial nerve, transports impulses for sense of smell to the brain. The olfactory nerve is capable of regeneration.
The olfactory nerve carries impulses from odor-detecting cells to the brain.

boy
The olfactory nerve, or 1st cranial nerve.
Receptors or more precisely, sensory receptors.
Sensory neuron
Nerve impulses are initiated and transmitted according to nerve reactions and messages that get passed along or transmitted along nerve synapses and zones.
