Structure of the dermal scales in gymnophiona (Amphibia)
Journal of Morphology, 1980AbstractHistology and cytology of dermal scales of the gymnophionans Ichthyophis kohtaoensis and Hypogeophis rostratus reveal their structure and the nature of their mineralization.Dermal scales are small flat disks set in pockets in the transverse ridges of the skin. Each pocket contains several scales of various sizes.

Abstract Caecilians are a monophyletic group of elongate, snakeor wormlike amphibians lacking all trace of limbs and girdles, and with tails reduced or absent (Fig. 1). 7ey are one of the three orders of the extant Lissamphibia, the Gymnophiona (naked snakes), and are most likely the closest relatives of the more familiar frogs and ...

The indirect immunofluorescence method was used to identify and locate LTH-, STH-, LH-, TSH-, ACTH- and MSH-immunoreactive cells in the pituitary of Typhlonectes compressicaudus (Gymnophiona). The present study defines the histological and histochemical staining properties of each cell type identified.

The trunk musculature of caecilians (Amphibia: Gymnophiona)
Journal of Morphology, 1980AbstractDescriptions of the trunk musculature of six species representing sex genera and five families of caecilians reveal considerable variation, which may be useful in future systematic studies. The muscle units of the external muscular sheath (M. dorsalis trunci, M.

Ultrastructure of the mature spermatozoa of caecilians (Amphibia: Gymnophiona)
Journal of Morphology, 2003AbstractThe spermatozoa of Gymnophiona show the following autapomorphies: 1) penetration of the distal centriole by the axial fiber; 2) presence of an acrosomal baseplate; 3) presence of an acrosome seat (flattened apical end of nucleus); and 4) absence of juxta‐axonemal fibers.

Tooth crown morphology in caecilians (Amphibia: Gymnophiona)
Journal of Morphology, 1979AbstractThe morphology of tooth crowns is variable inter‐specifically among caecilians. Cusp number and shape, crown dimensions, and crown curvature characterize various species and have both functional and phylogenetic implications. Ichthyophis, Uraeotyphlus, Hypogeophis, and Geotrypetes have bicuspid teeth; Dermophis, Gymnopis, Caecilia, and ...
