All neurons have a cell body and one or more fibres. These fibres vary in length from microscopic to over 1 metre. There are two different kinds of nerve fibres: fibres that carry information towards the cell body, called dendrites, and fibres that carry information away from it, called axons.
The flute has also always been an essential part of Indian culture and mythology, and the cross flute believed by several accounts to originate in India as Indian literature from 1500 BCE has made vague references to the cross flute. Acoustics
In 2004 archeologists from TÃ¼bingen University also discovered an ancient flute in a cave located in Germany. This flute was 18.7 cm (7 3/8 in.) long and had three finger holes. It was carved from a mammoth's tusk by European Ice Age dwellers. This flute has been dated to at least 30,000 years old.
