Question

The A is a structure located on the B, which contains that act as auditory receptors. Choose the correct option for A, B and C
a) A-tectorial membrane, B - hair cells, C-basilar membrane
b) A-hair cells, B-tectorial membrane, C-basilar membrane
c) A-organ of Corti, B - basilar membrane, C-hair cells
d) A-basilar membrane, B - hair cells, C-tectorial membrane
​

Answer 1

Answer:

Explanation:

c is right option as the basilar membrane is a stiff structural element within the cochlea.

hope it helps u.

Answer 2

Answer:

The correct answer is option c) A-organ of Corti, B - basilar membrane, C-hair cells.

Explanation:

To identify the structures, we need to find out some clue from the question given.

We will start in opposite order, i.e., from C. It is given that C acts as auditory receptors. And we know that the structures which act as auditory receptors are hair cells. Hence, structure C are the hair cells.

According to the question, Structure C is present inside structure A. We know that hair cells are found within the spiral organ of Corti. Hence, structure A is organ of Corti.

Now, structure A is located on structure B. Organ of Corti is locaed on a membrane called 'basilar membrane'. Hence, structure B is basilar membrane.

So, the correct answer is option c.
