The contains vertically arranged maculae that would provide feedback of body movement in the vertical plane

"The saccule contains vertically arranged maculae that would provide feedback of body movement in the vertical plane."

The saccule is a group of sensory cells that's in the inner ear. When there head movements that are in the vertical plane, these cells in the macula are disturbed from their position and inform the connecting neurons that movement that's taking place. This information is taken to the vestibular nuclei.

Is there any pictures in the question? i can’t answer the question without seeing the model.

True statement gravity force is more on bigger mass, less on smaller mass.all mass fall on planet with same acceleration and speeds
