Question

Quizplus · Accepted Answer

The otoliths, small grains of calcium carbonate, are an essential part of the maculae involved in static equilibrium. They are attached to hair cells and their movement in response to changes in the position of the head help to detect changes in gravity and acceleration. Choice A refers to the organ of hearing and is not involved in static equilibrium. Choice C refers to a structure in the semicircular canals that is involved in dynamic equilibrium. Choice D refers to a canal in the inner ear and is not directly involved in equilibrium.
