A) They both contain maculae.
B) They are located in the vestibule of the ear.

D) They help adjust posture when a person changes the position of the head.
E) All of these are true of the utricle and saccule.

Utricle

A part of the inner ear involved in sensing linear accelerations and head-tilt positions relative to gravity.

Saccule

A small, bed-like structure in the vestibular system of the inner ear, contributing to the sense of balance.

Maculae

Specialized structures in the inner ear responsible for detecting linear acceleration and head position relative to gravity.
