Fictive Quadrupedal Walking

This week Arikawa et al. find that in the small white butterfly, the sexes actually see the world differently. The authors compared the male and female eyes of Pieris rapae crucivora that are equipped with three classes of photoreceptors sensitive to short-wavelength light. In both sexes, the authors detected mRNAs for three novel opsins, one per type of photoreceptor. Intracellular recordings ...

The Dynamics of Quadrupedal Walking

LOCOMOTION involves the harmonious activity of the entire animal depending especially on the co-ordinated action of the muscles, bones, nervous system and sense organs. A study of animal motion therefore deals with mechanical aspects of the integrated action of physiological systems which are more frequently studied separately. In the present investigation a preliminary analysis is made of the ...

The mammalian humeral retractors latissimus dorsi, teres major and caudal parts of the pectoral muscles are commonly thought to contribute to forward impulse during quadrupedal locomotion by pulling the body over the supporting forelimb. While most electromyographic studies on recruitment patterns for these muscles tend to support this functional interpretation, data on muscle use in chimpanzee...
