**Core Concept**
Falanga refers to a form of torture that involves the beating of the soles of the feet, often with a stick or other blunt object. This method of torture causes severe pain, bruising, and swelling of the feet and ankles due to the rich nerve supply of the plantar surface.

**Why the Correct Answer is Right**
The mechanism of falanga involves the stimulation of nociceptors in the plantar surface of the foot. The plantar surface contains a high density of nerve endings, including nociceptors that respond to painful stimuli. When the soles of the feet are beaten, these nociceptors are activated, leading to the transmission of pain signals to the brain. The pain is further exacerbated by the inflammation and swelling that occurs as a result of the trauma.
