Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Sounds are sent from the cochlea to the brain.
A
true
B
false
Explanation: 

Detailed explanation-1: -The cochlea is filled with a fluid that moves in response to the vibrations from the oval window. As the fluid moves, 25, 000 nerve endings are set into motion. These nerve endings transform the vibrations into electrical impulses that then travel along the eighth cranial nerve (auditory nerve) to the brain.

Detailed explanation-2: -Signals from the right ear travel to the auditory cortex located in the temporal lobe on the left side of the brain. Signals from the left ear travel to the right auditory cortex. The auditory cortices sort, process, interpret and file information about the sound.

Detailed explanation-3: -This transmits waves of sound through the cochlear fluid, sending the organ of Corti into motion. Fibers near the upper end of the cochlea resonate to lower frequency sound. Those near the oval window respond to higher frequencies.

Detailed explanation-4: -Sound waves travel through your ear canal to your eardrum and cause it to vibrate. The vibrations travel from your eardrum to your ossicles (tiny bones in your middle ear). Your ossicles send the vibrations to your cochlea (a spiral cavity in your inner ear that’s lined with hair cells).

Detailed explanation-5: -The cochlea is a hollow, spiral-shaped bone found in the inner ear that plays a key role in the sense of hearing and participates in the process of auditory transduction. Sound waves are transduced into electrical impulses that the brain can interpret as individual frequencies of sound.
