Morphology and mechanics of myosepta in a swimming salamander (Siren lacertina).
In contrast to the complex, three-dimensional shape of myomeres in teleost fishes, the lateral hypaxial muscles of salamanders are nearly planar and their myosepta run in a roughly straight line from mid-lateral to mid-ventral. We used this relatively simple system as the basis for a mathematical model of segmented musculature. Model results highlight the importance of the mechanics of myosepta...
متن کاملOutline of the Cranial Nerves
This volume is a symposium on the effects of alcohol on human life. It is not intended as a hand-book for scientists; it is arranged for the educated layman that he might have an adequate and authoritative source of information. It is a book that has value for physicians and nurses, even though they be familiar with the general material. The titles of the six parts of the treatise indicate the ...
متن کاملElectrodiagnosis of the cranial nerves.
Isolated facial weakness suggests either a contralateral hemispheric lesion or a disease of the facial nerve per se. The presence of sensory symptoms usually indicates a central facial weakness, which characteristically involves the lower part of the face. In contrast, the absence of sensory disturbances suggests a peripheral nerve lesion, some system diseases such as amyotrophic lateral sclero...
متن کاملPatterns of axial and appendicular movements during aquatic walking in the salamander Siren lacertina.
Most studies of salamander locomotion have focused either on swimming or terrestrial walking, but some salamanders also use limb-based locomotion while submerged under water (aquatic walking). In this study we used video motion analysis to describe the aquatic walking gait of Siren lacertina, an elongate salamander with reduced forelimbs and no hindlimbs. We found that S. lacertina uses a biped...
متن کاملHistomorphogenesis of cranial nerves in Huso huso larvae
In this study the cranial nerves development of H. huso are explained from 1 to 54-days-old (1, 3, 6, 15, 21 and 54 days). Despite all the researches on fish brain, there are no study on nerves evolution on H. huso during their larvae life. For this research 40 samples of larvae H. husowere obtained (from each age, about six samples were selected). The specimens were ...
