Question

Organ of Corti is located on the:

• A. Tectorial membrane
• B. Basilar membrane
• C. Reissner's membrane
• D. Tympanic membrane

Hint:

Damage to the hair cells within the Organ of Corti is a common cause of sensorineural hearing loss, highlighting the importance of protecting hearing by avoiding exposure to loud noises.

Answer 1

The Correct Option is B

To solve the problem, we need to identify the membrane where the Organ of Corti is located.

1. Understanding the Organ of Corti:
The Organ of Corti is located in the cochlea of the inner ear and is responsible for converting sound vibrations into neural signals. It is located on the basilar membrane, which supports the sensory cells (hair cells) that detect sound vibrations.

2. Analyzing the Options:
Let's consider the membranes mentioned:

• Tectorial membrane: This membrane is located above the Organ of Corti and plays a role in stimulating hair cells but is not where the Organ of Corti is located.
• Basilar membrane: This is the correct location for the Organ of Corti. The Organ of Corti is situated on top of the basilar membrane in the cochlea.
• Reissner’s membrane: This membrane separates the scala vestibuli and scala media in the cochlea, but it is not where the Organ of Corti is located.
• Tympanic membrane: Also known as the eardrum, it is located outside the ear and is not related to the Organ of Corti.

Final Answer:
The correct option is (B) Basilar membrane.
