Number of muscle fibres composing appendicular muscles in the adult fly defined by examining leg muscles from the five adult MHC-tauGFP females and males. Minor variations in the number of muscle fibres were observed in nearly all muscles (except for trrm, ltm2 and tarm2). These variations are independent of sex and leg pair
The tadm muscle of the first leg is composed of a markedly lower number of muscle fibres than its counterparts in the second and the third leg pair. The differences in the number of tadm muscle fibres are independent of sex
