Which of the following is the main function of cochlea?AAmplifies the soundBconverts the sound to electrical signalsCboth 1 and 2DNone of these

Break Down the Problem

1. Identify the function of the cochlea in the auditory system.
2. Examine the options provided for their relevance to the cochlea's function.

Relevant Concepts

• The cochlea is a spiral-shaped organ in the inner ear responsible for converting sound vibrations into neural signals.
• It contains hair cells that transduce mechanical sound energy into electrical signals sent to the brain.

Analysis and Detail

• Option A: Amplifies the sound: This function primarily belongs to the outer and middle ear structures, not specifically to the cochlea.
• Option B: Converts the sound to electrical signals: This is the primary function of the cochlea, where sound waves are transformed into electrical impulses via hair cells.
• Option C: Both 1 and 2: This option implies the cochlea both amplifies and converts sound, which isn't entirely accurate.
• Option D: None of these: This option would be incorrect given the known function of the cochlea.

Verify and Summarize

The cochlea’s main role is to convert sound to electrical signals. Therefore, the other option about amplification is misleading in the context of the cochlea specifically.

Final Answer

B. Converts the sound to electrical signals is the correct answer.
