What did they wear? The Indus valley people were the first in the world to spin cotton and woollen yarn. Needles and buttons have been found there. They knew the art of weaving and stitching. The men used to wear a loin cloth akin to a dhoti that is still worn by a large number of Indians
The inner ear has a sensory receptor inside the cochlea called the Organ of Corti. It is responsible for holding the hair cells, which are the nerve receptors for hearing. Movements of the middle ear bones create a mechanical energy that pushes on a membrane in the cochlea, causing the cochleaâs fluids to move.
The small bone called the stirrup, one of the ossicles, exerts force on a thin membrane called the oval window, transmitting sound pressure information into the inner ear. The inner ear can be thought of as two organs: the semicircular canals which serve as the body's balance organ and the cochlea which serves as the body's microphone, converting sound pressure impulses from the outer ear into electrical impulses which are passed on to the brain via the auditory nerve.
