Correctly identify the following anatomical features of the olfactory receptors.

The olfactory nerve is a sensory nerve that carries olfactory information from the nasal cavity to the brain and constitutes the first cranial nerve. From an anatomical perspective, it courses in close proximity with the terminal nerve and the vomeronasal nerve, although the three nerves can be easily distinguishable.Perception of chemical stimuli from the environment is essential to most animals; accordingly, they are equipped with a complex olfactory system capable of receiving a nearly unlimited number of odorous substances and pheromones.
