The musculature of horsehair worm larvae (Gordius aquaticus, Paragordius varius, Nematomorpha): F-actin staining and reconstruction by cLSM and TEM
Zoomorphologie - Tập 123 - Trang 45-54 - 2003
The musculature of larvae of Gordius aquaticus was investigated by laser-scanning microscopy and compared to transmission electron microscopic data for the larva of Paragordius varius. In the anterior portion of the body, the preseptum, four different muscle groups can be distinguished: (1) 12 anterior parietal muscles in the body wall, (2) six oblique muscles that function as retractors of the in......
Light and electron microscope studies of some brachiopod and pogonophoran setae
Zoomorphologie - Tập 74 - Trang 253-270 - 1973
The structure of the setae and setal sacs inLingula anatina Bruguié,Macandrevia cranium (O. F. Müller) (syn.Waldheimia c.),Terebratulina retusa (Linné) (T. caput-serpentis auct.) (Brachiopoda),Siboglinum fiordicum Webb andS. ekmani Jägersten (Pogonophora) are studied by light and electron microscopy.

Structure and phylogenetic interpretation of diplopod eyes (Diplopoda)
Zoomorphologie - Tập 98 - Trang 241-260 - 1981
The structural organization of the ocelli of several diplopod species has been studied by means of electron microscopy. The results provide evidence that diplopodan ocelli are derived from typical mandibulate ommatidia, which consequently had been present in diplopod ancestors. The recent representatives of the two sister groups, Pselaphognatha and Chilognatha are characterized by two essentially ......

Formation of buccal armature of Cadlina laevis (Linnaeus, 1767) (Nudibranchia, Gastropoda)
Zoomorphologie - Tập 141 - Trang 245-261 - 2022
The features of the buccal armature’s morphology and formation process may have phylogenetic significance, be adaptive to the feeding strategy or both. The monophyletic order of gastropods—Nudibranchia—has various feeding strategies and diversified morphology of the buccal armature. That makes nudibranch molluscs a suitable model group for studying the structure and synthesis of the buccal armatur......

Histologische untersuchungen über die entwicklung des zeckenadultus in der nymphe
Zoomorphologie - Tập 35 - Trang 535-585 - 1939
Die Nymphencuticula besteht aus hartem, weichem und Gelenkchitin. Das harte Chitin setzt sich aus zwei Lagen zusammen: Tektostracum und Ektostracurn. Das Tektostracum stellt ein diinnes ungegliedertes Oberflächenhäutchen dar, während das Ektostracum von dichtstehenden Kanälchen durchsetzt ist. Das weiche Chitin enthält drei Schichten: das Tektostracum, Ektostracum und das horizontal geschichtete H......
Bone microstructure in finite element modeling: the functional role of trabeculae in the femoral head of Sciurus vulgaris
Zoomorphologie - - 2019
In arboreal habitats, animals encounter substrates of varying inclinations. Consequently, the external loads acting on the limb bones during arboreal locomotion are diverse in terms of magnitude and orientation. It is not well understood how limb bones are adapted to a broad range of loading directions and which functional role is adopted by the trabecular microstructure in particular. In this stu......
Feinstruktur des ventralen mandibulären Muskelrezeptors bei Liposcelis bostrichophilus (Insecta, Psocoptera)
Zoomorphologie - Tập 108 - Trang 353-358 - 1989
Der ventrale Mandibel-Muskelrezeptor wird im Kopf von Liposcelis bostrichophilus (Psocoptera) nachgewiesen. Er zieht, median der Mandibel-Gelenkachse gelegen, vom vorderen Tentorium-Arm zur hinteren Mandibel-Basis und wird also während der Abduktion der Mandibel gedehnt. Der Rezeptor besteht aus einer motorisch und sensorisch innervierten Muskelfaser und 10 bipolaren, multiterminalen Sinneszellen.......
Morphogenesis accompanying larval metamorphosis in Plakina trilopha (Porifera, Homoscleromorpha)
Zoomorphologie - Tập 129 - Trang 21-31 - 2009
Morphological investigations of morphogenesis accompanying the metamorphosis of the cinctoblastula larva of poriferan Plakina trilopha (Homoscleromorpha) have been made. The larva possesses a distinct columnar epithelium which subdivides into three cellular areas: antero-lateral, postero-lateral, and posterior one. Characteristic morphological features of the cells in each area can be used as natu......
