Description: | Eugen Albrecht Universitats-Mechanikus Tubingen. MANU Eugen Albrect late 19th early 20th century Tubingen, Germany. DES after MAREY,Etienne,Jules. second half 19th century Paris, France. This is Marey's registering tambour used for recording muscle extension or contraction induced by an electric potential. It is a pneumatic instrument. The perforated aluminium disc (for lightness) was fixed with Chatterton's compound to the outside of a latex memrane strecthed over the tambour which was also sealed with Chatterton's compound. The reed lay on the rest on the aluminium disc. The lever arrangement magnified the signal which was recorded, on the myograph plate, by a grass stem stylus. In Marey's work the tambour recorded the movement of the muscle on a pendulum myograph. The tambour was connected by a rubber tube to Marey's 'Pince Myographic' which detected the muscle extension or contraction . It consisted of a tambour with a clip which gripped the muscle under study. One arm of the clip was in contact with the membrane on the tambour the change in size of the muscle was transmitted to the tambour thence to the registering tambour by a rubber tube. | License: | http://www.hmag.gla.ac.uk/spirit/rights/ | Publisher: | Hunterian Museum and Art Gallery, University of Glasgow | Rights holder: | Hunterian Museum and Art Gallery, University of Glasgow | Subjects: | SCIENTIFIC COLLECTION : | Source: | Hunterian Museum | Creator: | Hunterian Museum and Art Gallery, University of Glasgow | Identifier: | http://www.huntsearch.gla.ac.uk/cgi-bin/... | Language: | en-GB | Go to resource |
