Geruchssystems
Geruchssystems, also known as the olfactory system, refers to the sensory and neural structures that detect and interpret odorant molecules. It includes the peripheral detection apparatus in the nasal cavity and the central neural pathways that process olfactory information, ultimately contributing to perception, memory, and emotion.
In the nose, odorant molecules dissolve in mucus and bind to receptors on the cilia of olfactory
From the olfactory bulb, mitral and tufted cells project via the olfactory tract to several cortical areas,
Mechanistically, odor coding is combinatorial: a given odor activates a pattern of receptors, producing a unique
Clinical aspects: olfactory dysfunction can be congenital or acquired (anosmia, hyposmia). Causes include upper respiratory infections,
