where in the nose are the nerve ending for smell located
Olfactory nerve The afferent nerve fibers of the olfactory receptor neurons, transmit nerve impulses about odors to the central nervous system, where they are perceived by the sense of smell (olfaction). Derived from the embryonic nasal placode, the olfactory nerve is somewhat unusual among cranial nerves because it is capable of some regeneration if damaged. The olfactory nerve is sensory in nature and originates on the olfactory mucosa in the upper part of the nasal cavity.[1] From the olfactory mucosa, the nerve (actually many small nerve fascicles) travels up through the cribriform plate of the ethmoid bone to reach the surface of the brain. Here the fascicles enter the olfactory bulb and synapse there; from the bulbs (one on each side) the olfactory information is transmitted into the brain via the olfactory tract.[2] The fascicles of the olfactory nerve are not visible on a cadaver brain because they are severed upon removal.[3] :548
Skin appendage Skin appendages are derived from the skin, and are usually adjacent to it.[1]
Ventral root of spinal nerve In anatomy and neurology, the ventral root or anterior root is the efferent motor root of a spinal nerve.
Sensory neuron Similarly to olfactory receptor neurons, taste receptors (gustatory receptors) in taste buds interact with chemicals in food to produce an action potential.
