Show Answer & Explanation ▾
✓ Correct Answer: A. Neurons of olfactory epithelium
Smell is perceived in the olfactory region of the nose, which is situated high up in the nasal cavity (upper 1/3 rd of nasal cavity). Olfactory area is also called the dangerous area of the nose. Esthesioneuroblastoma (Olfactory Neuroblastoma) arises from the olfactory epithelium. Olfactory pathway: Neurons of olfactory epithelium → Olfactory nerves → Pass through the cribriform plate → Mitral cells of the olfactory bulb → Olfactory tract → Prepyriform cortex and amygdaloid nucleus. Olfactory system is also associated with the autonomic system at the hypothalamic level.
