What does "phantom sensation" refer to?

  1. Feeling pain in a missing limb

  2. Sensation that a body part is still present

  3. Being able to move a limb after amputation

  4. Loss of sensory function

The correct answer is: Sensation that a body part is still present

Phantom sensation refers to the experience of feeling that a body part is still present even after it has been amputated. This phenomenon is common among individuals who have undergone limb removal, where sensations such as tingling, warmth, or even pain can be felt in the area where the limb used to be. This feeling occurs due to the way the brain processes sensory information and can misinterpret signals from the nervous system associated with the missing limb. It's important because understanding phantom sensations can help healthcare providers address the emotional and physical complications experienced by amputees, ultimately aiding in their rehabilitation process.
