Myology of the pectoral girdle of the golden hamster
… This study is concerned with the myology of the pectoral girdle of the golden hamster. The pectoral girdle is compared with that of the laboratory rat (Greene, 1935), the wood rat (Howell, 1926), the kangeroo rat (Howell, 1932), the pocket gopher (Hollinger, 1916) and the rabbit (Bensley, 1938). …

Investigating the Patterns of Convergence in Pectoral Girdle Reduction During the Evolution of Limblessness in Lerista (Scincidae)
… the skeletal elements that support the limb, the pectoral girdle, has been less thoroughly examined. Here, I use computed tomography to generate three dimensional models of the pectoral girdles of an Australian skink genus, Lerista. This group contains pentadactyl species, fully limbless species …

Humeral torsion and activity-related change in the human upper limb and pectoral girdle. A biomechanical investigation and social implications.
This project investigas humeral torsion and activity-related change in the human upper limb. Increased humeral torsion angles have been identified in the professional throwing athlete and may be associated with strenuous activity. The nature of humeral torsion as an osteogenic response to the …

A Comparison of the Pectoral Spines in Virginia Catfishes
Catfish pectoral spines are an anti-predator defense mechanism. They can be bound or locked, making the fish harder to swallow, or used to produce distress calls by rubbing ridges on the dorsal process against a channel in the wall of the pectoral girdle. Growth of the pectoral spine and girdle …

Sound Production in Two Loricariid Catfishes
<p>Many families of catfish produce sounds via pectoral spine stridulation and/or swim bladder compression using sonic muscles attached to the swim bladder. The sound production capabilities and characteristics in Loricariidae, the largest catfish family, have not been well examined. Sounds …

The Rise of Modern Avian Flight: Wing Movement and Joint Mobility Within Ornithurae
… the associated locomotor specialisations in the pectoral girdle of living birds. I developed a novel technique for the retrodeformation of taphonomically deformed fossils to reconstruct the remains of *Ichthyornis*. To decipher a link between 3D wing joint mobility and the flight ecology in …

Eine Studie zur Entwicklung der Scapula-Klinge : ein neuer Pfad der Skelett-Entwicklung beim Vogel-Embryo
Die Scapula-Klinge geht aus axialen Strukturen, den Dermomyotomen, hervor. Anhand mikrochirurgischer Operationen am Hühner-Embryo wird der Einfluss umliegender Signalgeber und intrinsischer Positionsinformation auf die Entwicklung der Scapula-Klinge untersucht. Es wird ein Modell vorgeschlagen, …
