Which Ion Causes Depolarization in Olfactory Neurons

Question

Which ion causes depolarization in olfactory neurons? A) Na⁺ B) Ca²⁺ C) K⁺ D) Both Na⁺ and K⁺ are correct. E) Both Na⁺ and Ca²⁺ are correct.

Accepted Answer

Depolarization in olfactory neurons is primarily caused by the influx of sodium (Na+) and calcium (Ca2+) ions. Sodium ions initiate the depolarization, and calcium ions further contribute to the process.
