The inner ear also contains the vestibular organ that is responsible for balance.This crossword clue Where the tiny hammer, anvil, and stirrup bones are in the human body was discovered last seen in the Maat the Crosswords With Friends Crossword. The brain then interprets these signals, and this is how we hear. These nerve endings transform the vibrations into electrical impulses that then travel along the eighth cranial nerve (auditory nerve) to the brain. As the fluid moves, 25,000 nerve endings are set into motion. The cochlea is filled with a fluid that moves in response to the vibrations from the oval window. The sound waves enter the inner ear and then into the cochlea, a snail-shaped organ. The Eustachian tube, which opens into the middle ear, is responsible for equalizing the pressure between the air outside the ear and that within the middle ear.
The tiny stapes bone attaches to the oval window that connects the middle ear to the inner ear. The three bones are named after their shapes: the malleus (hammer), incus (anvil) and stapes (stirrup). The ossicles are actually tiny bones - the smallest in the human body. The vibrations from the eardrum set the ossicles into motion. Sound waves cause the eardrum to vibrate. The sound waves then travel toward a flexible, oval membrane at the end of the ear canal called the eardrum, or tympanic membrane. It collects sound waves and channels them into the ear canal (external auditory meatus), where the sound is amplified.
The auricle (pinna) is the visible portion of the outer ear. Understanding the parts of the ear - and the role of each in processing sounds - can help you better understand hearing loss.
