TRUE/FALSE. like all other sensory pathways, the nerve impulses associated with olfaction are routed through the thalamus on the way to the primary olfactory cortex.



Answer :

It is FALSE that all other sensory pathways, the nerve impulses associated with olfaction are routed through the thalamus on the way to the primary olfactory cortex.

The olfactory nerve, also called cranial nerve I, the first cranial nerve, or just CN I, is a cranial nerve that houses sensory nerve fibers related to the sense of smell. Our olfactory system and sense of smell are made possible by this nerve. The shortest sensory nerve is the first cranial nerve. The olfactory nerve originates in the brain and terminates in the upper inside portion of the nose.

The olfactory receptor neurons' afferent nerve fibers deliver nerve impulses concerning scents to the central nervous system (olfaction). The olfactory nerve, which is descended from the embryonic nasal placode, is relatively unique among the cranial nerves in that it has some regeneration potential if injured. The olfactory mucosa in the upper section of the nasal cavity is the site of the origin of the sensory olfactory nerve.
