Distribution Pattern of Muscle Fiber Type in Musculus Biceps Brachii of White-Handed Gibbon

Abstract

Histochemical examinations of muscle fiber types by Sudan black B staining were made on m. biceps brachii of male and female white-handed gibbon (Hylobates lar). Three types of muscle fibers could be discriminated in terms of the reaction to the pigment and the cellular diameter : red muscle fiber (type I) with a positive reaction and a small diameter ; white muscle fiber (type II) with a weak reaction and a large diameter ; intermediate muscle fiber (type III) with an intermediate reaction and diameter.Of 4648 muscle fiber cells, in average of male and female, scanned in the cross-section, red muscle fibers accounted for 44.1%, white muscle fibers 28.3%, and intermediate muscle fibers 27.6%, respectively.White muscle fibers were clearly localized in the external layers of both heads of m. biceps brachii.In contrast, red muscle fibers were more evenly distributed throughout the muscle though moderately localized in the regions adjacent to the sulcus bicipitalis medialis. Intermediate muscle fibers showed no specific localization at all. These results suggest that m. biceps brachii of the gibbon, an acrobatic armswinger, is inclined to be a red muscle that is fatigue-resisting rather than power-generating.

Fiber type population in limb muscles ofMicrocebus murinus

“…In Microcebus, as in other primate and non-primate mammals, glycolytic fibers have a larger cross-sectional area than oxidative ones; the opposite observation, by KIMURA et al (1987), concerning the m. biceps brachii of Nycticebus, appears to be an exception.…”

“…Within muscles, the three main types co-occur in predictable relationships with regard to functional requirements. Generally speaking, type I fibers are more deeply located while type II fibers are more superficially concentrated (BROOKE & KAISER, 1970;ARIANO et al, 1973;GONYEA & ERICSON, 1977;SICKLES • PINKSTAFF, 1981b;ARMSTRONG et al, 1982;McCONATHY et al, 1983;MCINTOSH et al, 1985;KIMURA ~;INOKUCHI, 1985;RoY et al, 1991).…”

Correlation between the Morphology of the Feet and Muscle Fiber Composition in the Anterior Tibial Muscle.

“…Given, however, the fact that observation in this study is limited to the anterior tibial muscle, the possibility cannot be excluded that the above differences merely represent phylogenetic features unrelated with the foot morphology. Frequencies of the red muscle fibers with slow contraction, intermediate muscle fibers with plastic contraction, and white muscle fibers with fast contraction, in particular, are reported to be closely correlated with the locomotion of various mammals (Hall-Craggs, 1975;Kimura and Inokuchi, 1985). Similarly, when the muscle fiber types are compared according to the morphology of the feet, the frequency of white muscle fibers with strong instantaneous response is high in apes and monkeys, rats, rabbits and bears (plantigrade type), while the frequencies of red and intermediate muscle fibers are high in humans, who are also classified as the plantigrrade type.…”

Sarcocystis found in the skeletal muscle of common squirrel monkeys

“…This is assumed to reflect the fact that the cyst was organized and encapsulated by septa formed between the cyst and the adjacent muscle fiber cells. The muscle fiber cells composing the skeletal muscle consist of three functionally different types (OGATA, 1958(OGATA, , 1960OGATA & MORI, 1964;KIMURA & INOKUCHI, 1985). The type I red fiber has a high lipid content, intensive activity of oxidoreductases and functions of tonus, posture, and adjustment, whereas the type II white fiber has a high polysaccharide content, intensive activity of anaerobic glycolytic enzymes and a phasic or kinetic contractile function.…”
