APPENDIX 2 in An integrative model of chimaera jaw links mechanical stress to localized cartilage mineralization

APPENDIX 2. — Calculation of the jaw adductor muscle force components in the adult specimen of Chimaera monstrosa Linnaeus, 1758 (MNHN-2022-362). Abbreviations: PCSA, physiological cross section area; Po, the muscle theoretical maximum tetanic force; TSPR, the specific tension of elasmobranch red muscle; α, the angle between the muscle vector and each axis at the muscle insertion on the lower jaw.
