Which of the following is not true of otoliths?

A) They cause the stereocilia to bend, which is the stimulus for sending nerve impulses to the cerebrum.
B) They consist of magnesium chloride.
C) They add weight to the otolithic membrane as the head is tilted, which causes it to sag.
D) They are embedded in the gelatinous portion of the otolithic membrane.
E) All of these are true of otoliths.

Otoliths

Otoliths are small, calcium carbonate crystals in the inner ear that contribute to the sense of balance and orientation by detecting head movements and gravity.

Stereocilia

Hairlike projections on the surface of certain cells, such as those in the inner ear, which are involved in the mechanosensation process.

Magnesium Chloride

A chemical compound often used in de-icing, dust control, and as a magnesium supplement in agriculture and medicine.
