Question

Low frequencies are best heard at the apex of the basilar membrane (near the helicotrema). What is the characteristic of the helicotrema?

1) Narrow and rigid
2) Wide and flexible
3) Located in the middle of the basilar membrane
4) Not present in the ear

Answer 1

The helicotrema is a narrow and flexible opening located at the apex of the basilar membrane.

Step-by-step explanation:

The helicotrema is a characteristic of the inner ear. It is a narrow and flexible opening located at the apex of the basilar membrane, near the round window and the oval window. The helicotrema allows for communication between the scala vestibuli and the scala tympani, which are two fluid-filled chambers in the cochlea.
