Question:
Transduction of mechanical energy into nerve impulses in the auditory system takes place in response to bending of the _________.
Transduction of mechanical energy into nerve impulses in the auditory system takes place in response to bending of the _________.
Show Hint
Remember: \textbf{Hair cells} in the cochlea are the sensory receptors that perform mechanical-to-neural transduction in hearing.

- pinna
- hair cells
- incus
- malleus
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Recall how auditory transduction occurs.
The process of converting sound waves (mechanical energy) into electrical signals (nerve impulses) occurs in the cochlea of the inner ear.
Step 2: Role of hair cells.
Inside the cochlea, hair cells bend in response to vibrations of the basilar membrane. This bending opens ion channels in the hair cells, leading to depolarization and generation of nerve impulses.
Step 3: Eliminate incorrect options.
- The pinna (A) collects sound waves but does not transduce signals.
- The incus (C) and malleus (D) are ossicles that transmit vibrations, but not responsible for neural transduction.
Hence, the correct answer is hair cells.

- In a locality, the houses are numbered in the following way: The house-numbers on one side of a road are consecutive odd integers starting from 301, while the house-numbers on the other side of the road are consecutive even numbers starting from 302. The total number of houses is the same on both sides of the road. If the difference of the sum of the house-numbers between the two sides of the road is 27, then the number of houses on each side of the road is:
