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
The Flute. The flute is made in the form of an open cylindrical air column about 66 cm long. Its fundamental pitch is middle C (C4) and it has a range of about three octaves to C7. Sound is produced from a flute by blowing onto a sharp edge, causing air enclosed in a tube to vibrate. The flute as shown above is a transverse or side-blown flute. The modern flute was developed by Theobald Boehm who experimented with it from 1832 to 1847, desiring to give it a bigger tone. He finally produced a parabolic (bowl-shaped) head joint attached to a cylindrical body with open-standing keys and finger pads to cover large finger holes.
