The least touched part of the body is likely the trunk. This is because the trunk has fewer touch receptors compared to other areas like the fingers, lips, or face.
While the question doesn't specify which parts of the body are considered "least touched," the trunk is a reasonable answer based on the provided information. Touch receptors are concentrated in areas of the body that are used for more sensitive tasks, like feeling texture or experiencing pain. The trunk, on the other hand, is less involved in these functions.
For example, the trunk is often covered by clothing, which limits the amount of direct contact it experiences. It's also less likely to be used for tasks that require fine motor skills or sensitivity.
Therefore, the trunk is a logical candidate for the least touched part of the body.
