This PDF covers the anatomy of the olfactory organ, including the olfactory region of the nasal cavity, olfactory epithelium, receptor neurons, and supporting cells. It explains odorant receptor organization, signal transduction, and the pathway from olfactory filaments through the cribriform plate to the olfactory bulb and cortex.

Central connections to limbic structures, olfactory coding, and clinical conditions such as anosmia and post-traumatic injury are presented in a clear visual format for understanding olfactory anatomy.
