**Question:** Phantom limb is an example of disorder of

A. Sensory perception
B. Motor function
C. Psychological adaptation
D. Neurological integration

**Core Concept:** Phantom limb is a condition experienced by amputees where they continue to feel sensations or perceptions as if the missing limb is still there, despite its absence. This is due to the incomplete or unresolved neurological processing of sensory information in the brain.

**Why the Correct Answer is Right:** Phantom limb is related to A, Sensory perception because it involves the perception and experience of sensations from a missing limb. The brain continues to process sensory information related to the missing limb, leading to the perception of phantom sensations.

**Why Each Wrong Option is Incorrect:**

A. Motor function (Option B) is incorrect because phantom limb is not related to motor function, which deals with voluntary muscle movements. The condition primarily involves sensory perception and processing in the brain.

C. Psychological adaptation (Option C) is not the primary cause for phantom limb. While psychological factors may play a role in how an individual copes with the loss of a limb and experiences phantom sensations, the condition is primarily a neurological issue.

D. Neurological integration (Option D) is partly correct, but not the primary cause. Phantom limb arises from the brain's inability to fully integrate the loss of a limb and adjust its sensory processing. However, the condition is primarily a sensory perception issue rather than a problem with neurological integration.

**Clinical Pearl:** Phantom limb is a complex phenomenon involving neurological processing, sensory perception, and psychological factors. It highlights the interplay between the brain, the sensory system, and the individual's response to limb loss. Understanding phantom limb can aid in providing appropriate support and treatment for amputees experiencing this condition.

**Correct Answer:** A. Sensory perception (Option A) is the correct answer because it represents the core aspect of phantom limb, which involves the brain's processing of sensory information from a missing limb, leading to the perception of phantom sensations.
