Torah Temimah cites Arachin 20a: erech of head/liver = full-person rate.

Core Text

הָאוֹמֵר “עֵרֶךְ רֹאשִׁי” אוֹ “עֵרֶךְ כְּבֵדִי עָלַי” נוֹתֵן עֵרֶךְ כֻּלּוֹ. מַאי טַעְמָא? “בְּעֶרְכְּךָ נְפָשׁוֹת” כְּתִיב.

English: One who says “the erech of my head” or “of my liver” pays the erech of the whole — because Scripture says “nefashot.”

Vital-limb = whole-person derasha.

Naming a vital organ is equivalent to naming the entire person for the fixed schedule.
