Majjā dhātu — marrow and neural proxy
Sixth tissue / inner filling
Majjā dhātu is shown along the central axial line to accommodate the traditional marrow and inner-filling sense while acknowledging neural glosses in modern teaching. This is a target-organ projection of a substance classification, not a claim that one measurable tissue occupies the plotted midline.

The dhātu sequence names majjā after asthi and treats it as an inner, filling tissue; modern translations differ on marrow versus neural glosses, so the midline proxy is broad.

Modern teaching account of majjā dhātu as marrow and related inner tissue; the axial placement is an editorial target-organ proxy, not an anatomical assertion.
