**Core Concept**
Morphine withdrawal occurs when an individual who is physically dependent on morphine suddenly stops or significantly reduces its use. This leads to a cascade of physiological reactions due to the absence of the opioid's effects on the **mu opioid receptors** in the brain.

Since the correct answer isn't specified, let's discuss the general concept. Morphine withdrawal symptoms include anxiety, agitation, insomnia, muscle aches, and runny nose among others.
