BACKGROUND Chorda tympani nerve is a branch of the facial nerve which enables perception of taste of 2/3 anterior part of tongue and it is responsible for unilateral parasymphatetic nerve supplying of the submandibular and sublinqual salivary glands. MATERIAL AND METHODS Prospective analysis of patients operated on middle ear in ENT Department Jagiellonian University of Krakow between 2004-20...

The bicuspid (mitral) valve complex of the human heart consists of functional units which include the valve leaflets, chordae tendineae and the papillary muscles. The mechanical properties of these functional units depend to a large extent on the link between the muscle and the valve. This link is usually arranged in a branching network of avascular tendinous chordae composed of collagen and el...

1 The regulation of the benzamil (Bz)-insensitive salt taste receptor was 2 investigated by intracellular Ca ([Ca]i), protein kinase C (PKC) and the Ca3 dependent serine-threonine phosphatase, calcineurin (PP2B), by monitoring chorda 4 tympani taste nerve responses to 0.1M NaCl solutions containing Bz (5x10 M) and 5 resiniferatoxin (RTX; 0-10x10 M) in Sprague-Dawley rats and in wildtype (WT) an...

The regulation of the benzamil (Bz)-insensitive salt taste receptor was investigated by intracellular Ca2+ ([Ca2+]i), protein kinase C (PKC), and the Ca2+-dependent serine-threonine phosphatase, calcineurin (PP2B), by monitoring chorda tympani taste nerve responses to 0.1 M NaCl solutions containing Bz (5x10(-6) M) and resiniferatoxin (RTX; 0-10x10(-6) M) in Sprague-Dawley rats and in wild-type...

Neural competition among multiple inputs can affect the refinement and maintenance of terminal fields in sensory systems. In the rat gustatory system, the chorda tympani, greater superficial petrosal, and glossopharyngeal nerves have distinct but overlapping terminal fields in the first central relay, the nucleus of the solitary tract. This overlap is largest at early postnatal ages followed by...

A rare case of anomalous chordae tendineae associated with mitral valve dysplasia was observed during necropsy in a 5year-old male Persian cat with a history of sudden death. Grossly, there was thickening of the mitral valve, which was connected to numerous, short and thickened chordae tendineae that were ectopically inserted into the myocardium. In addition, marked left atrial dilation and pul...

A Chinese woman was admitted to our hospital because of syncope. Transthoracic echocardiography revealed a hypertrophic basal interventricular septum of 15 mm with a sharp angle protruding into the left ventricular outflow tract. Moreover, an anomalous anterolateral papillary muscle (maximum width of 11 mm) was inserted into the left ventricular outflow tract, with short chordae tendineae conne...

Left ventricular cineangiography was performed in 37 patients with mitral regurgitation. Twenty-one patients had rheumatic mitral valve disease determined by careful surgical and pathologic examination, 10 had papillary muscle dysfunction, and six had chordae tendineae rupture. Fourteen of the 16 patients considered to have nonrheumatic mitral regurgitation were confirmed surgically; the other ...

The echocardiographic findings from six patients with ruptured chordae tendineae from the posterial mitral valve leaflet and three with ruptured chordae from the anterior leaflet are reported; in all cases the diagnosis was later proven by openheart surgery. The constellation of echocardiographic findings suggesting iruptured chordae tendineae to the posterior leaflet are: (1) The appearance of...
