Berling Holm, K. 2017. The Chorda Tympani Nerve. Role in Taste Impairment in Middle Ear Disease and after Ear Surgery. Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Medicine 1306. 54 pp. Uppsala: Acta Universitatis Upsaliensis. ISBN 978-91-554-9837-5. The chorda tympani nerve, also known as the taste nerve, runs uncovered through the middle ear cavity, a localizat...

In a two-bottle test, Sprague-Dawley rats preferentially consume a greater amount of hypotonic and isotonic NaCl solutions relative to water, whereas inbred Fischer 344 (F344) rats fail to prefer NaCl solutions at any concentration relative to water. To determine whether taste contributes to this strain difference, we measured the integrated neural responses of the chorda tympani nerve to a con...

the author studied anatomical variations of the origin of the chorda tympani nerve from the mastoid portion of the facial nerve. the studies were performed on 200 specimens of human temporal bone. it was found that the chorda tympani may arise from the facial nerve in three levels: most commonly from the mid third of its mastoid segment (70%), less commonly from the proximal third (20%), and ve...

Cardiac myxomas are one of the most common types of primary cardiac tumors and are associated with embolization, angina, and sudden death. Most cardiac myxomas arise from the fossa ovalis, while those that arise from the mitral valve are exceedingly rare and those that arise from the chordae are even rarer. We report the case of a 28-year-old Caucasian woman who suffered from a brain infarction...

The hearts of three children who died with Duchenne's progressive muscular dystrophy and features of mitral valve prolapse were examined to find if the valve disorder arose from cardiomyopathy due to the primary disease or from dystrophic changes in th mitral valve itself. Gross, histologic and ultrastructural features of mitral valve annulus, anterior and posterior leaflets, chordae tendineae,...

The mitral valve comprises four structures: annulus fibrosus, cusp tissue, chordae tendineae, and papillary muscles. The annulus fibrosus is strong at the base of the aortic cusp, where it forms part of the aortic valve ring, and weak at the base of the mural cusp. From every part of the annulus cusp tissue hangs vertically downwards into the cavity of the left ventricle in the form of a short ...

repair of the mitral valve is the treatment of choice for mitral valve regurgitation when the anatomy is favorable. it is well known that mitral valve repair enjoys better clinical and functional results than any other type of valve substitute. this fact is beyond doubt regardless of the etiology of the valve lesion and is of particular importance in degenerative diseases. this review analyzes ...

The present investigation was carried out on the papillary muscles of ten healthy mature dromedary camels. Anatomically, the papillary muscles are muscular projections from the walls of the right and left ventricles into their cavities. They are processing many nipples like processes. The apex of each muscle process is attached to cord-like tendons; chordae tendineae. The latter, are string-lik...
