Mouth and tongue — White Wall (Memphis)
Speech and the opening of the body
The anatomical identity is Osiris's mouth and tongue, the place of speech and ritual reanimation. The relic-site claim rendered here is the White Wall at Memphis, whose Osirian and restoration rites support the association, although neither Dendera nor Plutarch assigns a mouth part to Memphis; the site pairing is therefore editorial.

Sources
Mysteries of Osiris at Dendera (primary_canonical)
The White Wall (Memphis) receives a full Osirian rite and the Djed is erected at Rosetau; this supports a Memphite restoration association, not a literal mouth relic claim.
Pyramid Texts (primary_canonical)
Opening-of-the-mouth and speech restoration belong to Egyptian funerary restoration theology.
