Which sensory system is primarily involved in detecting pheromones?

The olfactory system is the sensory system primarily involved in detecting pheromones. Pheromones are chemical signals released by individuals that can influence the behavior or physiology of others of the same species, particularly in relation to mating and social interactions.

The olfactory system is responsible for the sense of smell and is equipped with specialized receptors that can detect a wide variety of chemical compounds in the environment, including pheromones. These receptors send signals to the brain, where the signals are processed and can lead to changes in behavior or physiological responses.

In contrast, the visual system is concerned primarily with processing light and images, the auditory system deals with sound perception, and the tactile system is responsible for touch and sensation. None of these other systems play a role in identifying chemical signals like pheromones, which is why the olfactory system is the correct answer.
