a Five transverse cross-sections of L. africana trunk tip with classified muscle fascicle segmentations overlayed. Schematics show where the respective cross-sections were taken. b Ratio of muscle types for L. africana trunk tip for five cross-sections. Total percentage of muscle types for all five slices in white letters. c Five transverse cross-sections of E. maximus trunk tip with classified muscle fascicle segmentations overlayed. Schematic shows where the respective cross-section was taken. d Ratio of muscle types for E. maximus trunk tips for five cross-sections. Total percentage of muscle types for all five slices in white letters. Scale bars (a, c), 20 mm.
