Māṃsa dhātu — muscle proxy
Third tissue / structural flesh
Māṃsa dhātu is placed over the upper-limb field to make the structural flesh category visually legible in a front silhouette. This is a target-organ and tissue proxy for a substance classification, not a claim that the whole dhātu resides in one limb or at one skin point.

The dhātu sequence names māṃsa as the muscle/flesh tissue and treats it as a product of prior nourishment; no body-surface point is prescribed.

Modern teaching language for māṃsa dhātu as muscle and flesh; the limb placement is an editorial visual proxy rather than an anatomical assertion.
