Question

Quizplus · Accepted Answer

Receptor cells responsible for smell, known as olfactory receptor neurons, are unique among neurons because they have the ability to regenerate. They die and are replaced on a regular basis, approximately every 30 to 60 days. This is unlike most other neurons, which do not regenerate or are replaced very infrequently.
