A type of sensory organ found in many invertebrates consists of a spherical, fluid filled chamber that contains grains of sand or other dense granules. The cells lining the chamber are mechanoreceptors with sensitive cilia that project into the lumen. The granules settle at the low point within the chamber, deforming the cilia underneath and stimulating the cells directly below them. In this sensory organ, the cells lining the chamber are mechanoreceptors specialised for detecting
A) pressure.
B) vibration.
C) stretch.
D) mechanical distortion.
E) touch.

Question

Quizplus · Accepted Answer

The described sensory organ functions by detecting mechanical distortion. The granules inside the chamber settle and deform the cilia of the mechanoreceptors, directly stimulating them through mechanical distortion.
