Comparative histochemical study of prosimian primate hindlimb muscles. II. Populations of fiber types

Abstract: The populations of fiber types in hindlimb muscles of the tree shrew (Tupaia glis), lesser bushbaby (Galago senegalensis), and the slow loris (Nycticebus coucang) were described and an attempt was made to correlate populations of fiber types and locomotor patterns. Muscle fibers were assigned to one of the following groups: fast-twitch glycolytic (FG), fast-twitch oxidative-glycolytic (FOG), and slow-twitch oxidase (SO). Histochemical techniques for the demonstration of alkaline- and acid-stable ATPase, succin… Show more

“…Differences in degree of life on the ground or in the tree may affect muscle action and cause a variation in composition of myofiber types (13,18). In this study, it is not clear whether individual variability in proportion of myofiber types and the presence or absence of SOG myofibers are caused by a difference in modes of life.…”

“…The soleus muscles of Japanese macaques had more SO myofibers than did the gastrocnemius and flexor digitorum superficialis muscles, as shown in prosimian primates (13) and cynomologus monkeys (1). The soleus muscles with many SO myofibers have been assumed to be active during standing as well as during locomotion, whereas the gastrocnemius and flexor digitorum superficialis muscle with many fasttwitch myofibers (FOG plus FG) is used for various types of locomotion: walking, running, and jumping as shown in cats (14,19).…”

“…On the other hand, Petter and Jouffroy [21] pointed out that the percentage of type I fibres in the knee and ankle extensors of the lightest primate species, Microcebus murinus (50-70 g) is much lower than in heavier primates (see Ariano et al [41], Sickles and Pinkstaff [43], Anapol and Jungers [19], Acosta and Roy [50]). Finally, the slow loris, whose postural repertoire includes not only pronograde standing, but also clinging and hanging in the widest variety of positions, lacks the strong contrast of the percentage of type I fibres between postural and nonpostural extensor heads; the three vasti, as well as soleus and gastrocnemius lateralis, are composed of 50-80% slow fibres and are totally lacking in type IIb fibres [45].…”

“…great numbers of slow fibres in muscles of the slow lorus, Sickles & Pinkstaff, 1981 ; for extensive comparative data, see also Ariano et al 1973 ;Armstrong, 1980). In the present investigation we extend such comparisons to include the phenomenon of fibre type regionalisation, as seen in homologous muscles of 3 species of commonly used laboratory animals, adding new measurements from rabbits and mice to those already collected in the rat (cf.…”
