Which of the following would be considered an atypical sense?

• A. Senses in the bowel
• B. Vision
• C. Audition
• D. Olfaction

Answer: (A)

The main idea is understanding that some senses are considered the classic five, while others come from internal bodily states. Vision, audition, and olfaction are exteroceptive, detecting external stimuli like light, sound, and odors. Senses in the bowel are visceral or interoceptive; they monitor the internal state of the gut—stretch, chemical contents, irritation, and other internal signals. Because these visceral sensations aren’t part of the standard five senses, they’re regarded as atypical.
