Three small bones of ear ossicles are advantageous as compared to one single bone for hearing.
Advertisements
Solution
The ear ossicles, malleus, incus, and stapes create a complex lever system. This design is advantageous for hearing because it:
- Increases the mechanical force of vibrations.
- Improves the efficient transmission of sound energy from the eardrum to the inner ear structures.
- Reduces the amplitude of vibrations.
Due to impedance matching, mammalian hearing is more sensitive and has higher frequency limitations than reptiles.
