Which of the following are considered sensory structures?

• A. Lips, teeth, tongue, and cheeks
• B. Eyes, ears, nose, and tongue
• C. Tongue, Nose, Eyes, Ears, and Skin
• D. Heart, lungs, kidneys

Answer: (C)

Understanding sensory structures means focusing on the organs that detect stimuli for our senses. The five standard senses rely on specific structures: eyes for sight, ears for hearing (and balance), nose for smell, tongue for taste, and skin for touch. The set that includes eyes, ears, nose, tongue, and skin covers all five primary sensory organs, making it the best fit because it represents the full spectrum of sensory detection.

Other options mix sensory and non-sensory parts. One group lists lips, teeth, tongue, and cheeks—teeth aren’t sensory organs, and while lips and cheeks can sense touch, they aren’t the main sensory structures. Another group omits skin, which is essential for the sense of touch. A final group lists internal organs like the heart, lungs, and kidneys, which are not sensory structures.
