A lower motor neuron lesion involves Pitta pushing Kapha in which dhatu?

• A. Rasa dhatu
• B. Rakta dhatu
• C. Majja dhatu
• D. Mamsa dhatu

Answer: (C)

In Ayurveda, Majja dhatu represents the nervous tissue and the nervous system as a whole. A lower motor neuron lesion is fundamentally a problem of motor neurons and their connections to muscles, leading to loss of voluntary movement and reflexes. That nervous-system-centric pathology fits best with Majja dhatu, since this tissue is the one that houses and supports nerve function. The idea of Pitta pushing Kapha in a dhatu describes how a fire-like (Pitta) transformation can drive Kapha’s obstructive or stability-causing influence within that tissue, which aligns with the disruption of neural conduction and function seen in LMN lesions. While the other tissues—Rasa, Rakta, and Mamsa—are involved in blood, plasma, and muscle structure, they do not directly correspond to the primary nervous-system pathology at the heart of a lower motor neuron lesion.
