... on the tissue considered (liver or skeletal muscle), as well as having more-efficient muscle mitochondria than the other two species . Mus mattheyi presents metabolic innovations to ensure its homeostasis, by generating more ATP per oxygen consumed. * These authors contributed equally to this work...

...Q. Bone; E. R. Brown; G. Travers ABSTRACT The respiratory flow of water over the gills of the cuttlefish Sepia officinalis at rest is produced by the alternate activity of the radial muscles of the mantle and the musculature of the collar flaps; mantle circular muscle fibres are not involved...

... of Biologists 1990 locomotion oxygen consumption muscles cockroaches Many small animals appear to scale rocks, stalks, tree trunks and other vertical surfaces effortlessly. One frequently quoted explanation (e.g. in Calder, 1984 ; Schmidt-Nielsen, 1983 , 1984 ; Vogel, 1988...

... muscle, ranges from 100 to 160. The corresponding K′ value for the APK reaction is somewhat controversial, and K′ values for the GPK, TPK and LPK reactions are not known. In this study, conventional and 31 P-NMR methods were used to evaluate the equilibrium constants for the APK, GPK, TPK and LPK...

...) is presented for the brown lemur, Lemur fulvus . The vastus intermedius is the sole contributor to muscle recruitment during quadrupedal resting postures. It exhibits consistently high levels of electrical activity during all locomotory behaviour. The vastus medialis is recruited least among these muscles...

...Robert Elson; Hans-Joachim Pflüger ABSTRACT The pleuroaxillary muscle of a forewing (M85) or hindwing (M114) in the locust is supplied by two motor neurones. Each of the two motor neurones innervates a different part of the muscle. Single impulses in these motor neurones produce small twitches...
