Question

Which of these structures are not present in the cochlea?

(a) Scala naturae

(b) Scala vestibuli

(c) Scala tympani

(d) Scala media

The question was posed to me in an international level competition.

The above asked question is from Neural Control and Coordination in division Neural Control and Coordination of Biology – Class 11

Answer 1

The correct choice is (a) Scala naturae

For explanation: The cochlea, which is a spiral bony structure of the labyrinth present in the inner ear, contains the scala vestibuli, the scala tympani and scala media. Scala naturae is not a part of the cochlea.
