The cochlea is located within the __________ portion of the __________ bone and coils in about ___________ turns. Uncoiled, it measures about _____________ inch.

The cochlea is a critical component of the inner ear responsible for transforming sound vibrations into neural signals. It is specifically located within the petrous portion of the temporal bone, which provides a protective environment and ideal acoustics for this delicate structure. The cochlea coils in about 2 and a half turns, which plays a role in its ability to separate different frequencies of sound due to its unique structure. When uncoiled, the cochlea measures approximately 1 inch in length.

This understanding of the cochlea's anatomy and its location within the petrous portion of the temporal bone highlights its importance in hearing function. The other options contain inaccuracies regarding either the location of the cochlea, the number of turns it coils, or its length when uncoiled, making them inconsistent with the recognized anatomical facts.
