The tracheal and bronchial parasympathetic ganglia in the cat were studied using the histochemical-tiocholine method of Koelle and Friedenwald and histological techniques. Intensively stained AChE-positive nerve structures, i.e., ganglia and nerve fibres on the wall of the trachea and bronchi, were observed. The ganglia were situated mainly on the(More)
The morphology and topography of the ciliary ganglion in the Egyptian spiny mouse were studied with use of histochemical and histological techniques. The ciliary ganglion of the Egyptian spiny mouse consisted of between 3 and 4 agglomerations of nerve cells. The largest was situated at the point where the ventral branch of the oculomotor nerve divides into(More)
The crystal structure of the esterase EstA from the cold-adapted bacterium Pseudoalteromonas sp. 643A was determined in a covalently inhibited form at a resolution of 1.35 A. The enzyme has a typical SGNH hydrolase structure consisting of a single domain containing a five-stranded beta-sheet, with three helices at the convex side and two helices at the(More)
Using the thiocholine method and histological techniques the intermesenteric plexus of the pigeon was studied. The intermesenteric plexus of this species is a plexo-ganglionic structure with several (five to seven) ganglia and nerve fibres. The ganglia have an oval-, spindle- or star-like shape. Single nerve cells along the nerve fibres were observed. The(More)
Using the thiocholine method and histological techniques, the topography and morphology of cardiac ganglia in midday gerbil, Egyptian spiny mouse, chinchilla laniger and pigeon were studied. The results demonstrated that cardiac ganglia in all investigated species are embedded in epicardial fat. They formed plexo-ganglionic structures. Each of them composed(More)
Using stained acryl latex-injected techniques, the arterial circle of the brain in Acomys cahirinus Desmarest was studied. Results revealed an important individual variability of investigated structure. Three morphological variants were found: (1) the lack of typical arterial circle--opened in front and the back side, (2) partial opened at the back side,(More)
Cells of the pterygopalatine ganglion in quail are elliptical, oval and often spindle shape. They have single nuclei, which are spindle or lentiform in shape. The rough endoplasmic reticulum was observed in a great amount, especially in the vicinity of nucleus. It was organised in structure corresponding to Nissl's body. The mitochondria are present mainly(More)
Using the thiocholine method of Koelle and Friedenwald and histological techniques, the otic ganglion in Egyptian spiny mouse (Acomys cahirinus, Desmarest) was studied. The ganglion was found to be a single oval cluster of neurocytes, situated at the medial and posterior surface of the mandibular nerve just above the maxillary artery. The ganglion is(More)
Using the thiocholine method of Koelle and Friedenwald and histological techniques the pterygopalatine ganglion in Egyptian spiny mouse (Acomys cahirinus, Desmarest) was studied. The ganglion was found to be a single irregular cluster of neurocytes, situated on the medial surface of the maxillary nerve. The ganglion is composed of oval, elliptical and(More)
The aim of this paper was to summarise the knowledge about the autonomic cardiac innervation. It is generally known, that the cardiac nervous system consists of nerve plexoganglionic structures located mostly around the strategic regions of the heart. They consist of two main types of components: parasympathetic neurons, which exert an inhibitory effect,(More)
