A) come from the stump of the amputated limb.

D) can be diminished if more of the limb is removed surgically.

Question

Quizplus · Accepted Answer

Sensations from phantom limbs are believed to be a result of brain reorganization, as the areas of the brain that previously received input from the amputated limb may now receive input from nearby areas. This results in the brain interpreting that input as coming from the missing limb, leading to sensations such as pain, tingling, or warmth. Removing more of the limb surgically is unlikely to diminish phantom limb sensations, as they are not caused by actual input from the amputated limb stump.
