The Ear: the Organ of Hearing

The Ear: the Organ of Hearing

The ear is the organ of hearing. The pinna of the outer ear collects sound waves and channels them along the external auditory meatus to the ear drum. The eardrum vibrates and mechanical waves are transmitted by the ossicles, three small bones of the middle ear-the malleus, incus and stapes-to the cochlea of the inner ear. The cochlea, a coiled tube filled with fluid, contains the organ of Corti. Fluid waves, created within the cochlea, excite nerve cells in the organ of Corti, which send impulses along the auditory nerve to the brain. The semicircular canals, the saccule and the utricle are concerned with balance and the posture of the body.

@freyajean i realize that sounds like a stupid question but i am just not a doctor and wondering about the exact sciences of the ear and how the environment may have a cause/effect relationship with birth defects.

0:45 The cochlea, a coiled tube filled with fluid, contains the organ of Corti. and what could happen if the cochlea was reversed as a birth defect?? what would be the results or outcome of this condition?
