fine structure of capillaries in the conus papillaris of the limbless lizard, ophisaurus apodus (anguidae, lacertilia).the conus papillaris of ophisaurus apodus consists of blood vessels and pigment cells. the capillary walls are formed by endothelial cells, scarce pericytes and basal laminae. the cell bodies are attenuated and the plasmalemma of their luminal and abluminal surfaces forms microvilli. the perivascular space is well developed, containing nerve fibers and their terminals. similar localization and ultrastructure of avian pecten oculi and lacertilian conus papillaris suggest homology of these structu ...1977922814
[role of the hippocampal cortex and dorsal ventricular margin in the conditioned reflex behavior of ophisaurus apodus].in lizards ophisaurus apodus, extinction of the motor alimentary conditioned reflex, discrimination of location of visual signals were disturbed, and the ability for reversal of the stimuli signal significance was completely lost following bilateral ablation of dorsal parts of the hippocampal cortex. elaboration of the motor alimentary reflex was not affected. the extent of disturbances depended on the volume of hippocampectomy. the defect resulting from the bilateral lesion of the dorsal ventri ...20067064572
[analysis of the conduction of visual, somatic and audiovibrational sensory information of the hippocampal cortex in the lizard].acute electrophysiological experiments on lizards ophisaurus apodus show that stimulation of both thalamic n. dorsolateralis anterior and medial forebrain bundle elicited short latency responses in the hippocampal cortex resembling in topic and patterns responses evoked by sensory stimuli in the same structure. ample lesion of n. dorsolateralis anterior and of medial forebrain bundle suppressed up to a complete block conduction of sensory (visual, somatic, audiovibratory) and tectal impulses to ...19836602303

[immunohistochemical analysis of the serotonin system in the brain of lizard ophisaurus apodus].the distribution of serotoninergic neurons (localization of somata, principal fiber tracts and projection zones) was investigated in the brain of the lizard ophisaurus apodus using a specific antibody directed against serotonin (5-ht). a comparison of the results with those of the literature revealed that in spite of minor variations in the distribution of 5-ht in the different reptiles examined there exist common features which correspond to a general organizational pattern.19902125525
skull anatomy and ontogeny of legless lizard pseudopus apodus (pallas, 1775): heterochronic influences on form.pseudopus apodus (pallas, 1775) is the largest extant legless species of the subfamily anguinae (anguimorpha, anguidae) living mostly in the sub-arid territories ranging from the balkan area in europe to kazakhstan in asia. the species of other two genera live in north america, south-east asia and north africa (ophisaurus) and europe and south-west asia (anguis). the interrelationships of anguinae are unresolved; this is in part the consequence of the insufficient knowledge of the cranial, postc ...201727981780

geographic distribution of bhanja virus.a review on the geographic distribution, vectors and hosts of bhanja virus (bunyaviridae) is based on reports about: isolations of the virus; antibody surveys. bhanja virus has been isolated in 15 countries of asia, africa and europe, and antibodies against it have been detected in 15 additional countries. vector range includes ticks of the family ixodidae (subfam. amblyomminae; not subfam. ixodinae): 13 species of 6 genera (haemaphysalis, dermacentor, hyalomma, amblyomma, rhipicephalus and boop ...19873108117
geniculo- and subthalamohypothalamic connections in the lizard: hrp study.reciprocal connections of the hypothalamus with the ventral nucleus of the lateral geniculate body and ventrolateral (subthalamic) nucleus were demonstrated in the lizard ophisaurus apodus using the retrograde and anterograde axonal tracing method following local hrp injection into the mamillary complex.19911725784
[study of the connections of the hippocampal (mediodorsal) cortex of ophisaurus apodus by means of horseradish peroxidase axonal transport].origin of afferent projections of the hippocampal (mediodorsal cortex in lizards (ophisaurus apodus) cells was revealed by studying retrograde transport of horseradish peroxidase. most labelled neurons were located in n. dorsolateralis anterior thalami, corpus mamillaris, n. raphe superior, ipsilateral dorsal cortex and contralateral hippocampal cortex. less neurons projecting to the hippocampal cortex were observed in the ventromedial part of basal telencephalon (tuberculum olfactorium, n. accu ...19836406917
comparative anatomy of the lower jaw and dentition of pseudopus apodus and the interrelationships of species of subfamily anguinae (anguimorpha, anguidae).the morphology of the lower jaw and teeth of the legless lizard pseudopus apodus (anguimorpha, anguidae, anguinae) from eurasia are described in detail and compared with those of other species of the subfamily anguinae. the lower jaw anatomy of pseudopus, especially the dentary and teeth, clearly differs from the genera ophisaurus and anguis. even so, ophisaurus is largely uniform in its lower jaw morphology across species. the teeth of north american ophisaurus are slender cylinders, the shafts ...201424482318
morphology and frictional properties of scales of pseudopus apodus (anguidae, reptilia).in the lizard family anguidae different levels of limb reduction exist up to a completely limbless body. the locomotion patterns of limbless anguid lizards are similar to the undulating and concertina movements of snakes. additionally, anguid lizards frequently use a third mode of locomotion, called slide-pushing. during slide-pushing the undulating moving body slides on the ground, while the posterior part of the body is pressed against the substrate. whereas the macroscopic and microscopic ada ...201525843915
evidence of gaba-immunopositive neurons in the dorsal part of the lateral geniculate nucleus of reptiles: morphological correlates with interneurons.the distribution and staining pattern of gamma-aminobutyric acid immunoreactivity have been examined by both light and electron microscopy in the dorsal part of the lateral geniculate nucleus of three reptilian species: the turtle chinemys reevesi, the lizard ophisaurus apodus and the snake vipera aspis. after perfusion of the animals with 1% paraformaldehyde and 1% glutaraldehyde and polyethyleneglycol embedding of the brains, the analysis of sections processed immunocytochemically with an anti ...19921641130
[study of the connections of supposed diencephalic connections of the limbic system of the lizard using the technic of axonal transport of horseradish peroxidase].connections of the anterior thalamic (n. dorsolateralis anterior, n. dorsomedialis) and habenular nuclei in lizards ophisaurus apodus were studied by means of hrp administration into these nuclei. it was shown that all nuclei have overlapping locations of afferent sources (basotelencephalic structures, nuclei of anterior and hippocampal commissures, lateral area of the hypothalamus, superior raphe nucleus) and overlapping projectional zones (mammillary complex, ventral tegmental area). besides c ...19873574549
[rudimentary stages of the extremities of scelotes gronovii (daudin) embryos, a south african scincidea reptile].the development of the limbs has been studied in 15 embryos of scelotes gronovii, found in 8 ovoviviparous females collected at saldanha bay, in south africa, cape province. this study leads to the following constatations: in all the young embryos of this species, their appears anlagen of anterior and of posterior limb-buds. the primordia of forelimb-buds retrogress early and disappear, whereas the primordia of hind limb-buds transform into rudimentary limbs which persist in adult. histological ...19761008558
[neural connections in the septum of lizards studied by the method of horseradish peroxidase axonal transport].septal connections in lizards (ophisaurus apodus) were studied by means of the massive iontophoretic hrp injection into the septum. reciprocal connections between the septum and both dorsal and mediodorsal cortex, projections of the nucleus of broca diagonal band and anterior thalamic nuclei (mainly dorsolateral) to the septum were revealed. reciprocal connections of the septum with the preoptic area, periventricular hypothalamic structures containing dopaminergic neurons, as well as with the nu ...19882459624
