Which organ is specifically responsible for sensory perception of smell?

• A. Olfactory bulb
• B. Gustatory bulb
• C. Optic nerve
• D. Auditory canal

Answer: (A)

The olfactory bulb is the correct answer because it plays a crucial role in the sensory perception of smell. Located at the base of the brain, just above the nasal cavity, the olfactory bulb processes information about odors. When air containing odor molecules enters the nasal passages, these molecules bind to olfactory receptors in the nasal epithelium. The signals generated by these receptors are transmitted to the olfactory bulb, where the information is then processed and relayed to other parts of the brain for further interpretation and response. In contrast, the gustatory bulb is related to the sense of taste, the optic nerve is responsible for vision, and the auditory canal is involved in hearing. None of these structures are associated with the sensory perception of smell, making the olfactory bulb the distinct organ responsible for this function.
