Correct Option
The correct option is Basilar membrane.
Explanation
The inner ear contains a coiled structure called the cochlea, which is responsible for hearing. Inside the cochlea, the Organ of Corti serves as the primary sensory organ for hearing, containing hair cells that act as auditory receptors.
Detailed Analysis
- Basilar Membrane: The Organ of Corti is located on the basilar membrane. The hair cells are present in rows on the internal side of the Organ of Corti. The basal end of the hair cells is in close contact with the afferent nerve fibres.
- Tectorial Membrane: This is a thin, elastic membrane located above the rows of hair cells. While it interacts with the stereocilia of the hair cells during sound transmission, it does not support the base of the Organ of Corti.
- Oval Window: This is a membrane-covered opening connecting the middle ear to the inner ear. It receives vibrations from the stapes bone but does not house the Organ of Corti.
- Scala Vestibuli: This is the upper fluid-filled chamber of the cochlea, ending at the oval window. It is a structural space rather than the membrane upon which the sensory organ rests.
Key Takeaway: The Organ of Corti acts as the auditory receptor and rests on the basilar membrane within the cochlea, while the tectorial membrane lies above the hair cells.
