Answer

A ampulla, B vestibule Explanation 1. Identify structures related to equilibrium and balance The structures responsible for equilibrium and balance in the ear are primarily located in the vestibular system, which includes the vestibule and the semicircular canals. The ampulla is part of the semicircular canals, which detect rotational movements. The vestibule contains the utricle and saccule, which detect linear accelerations and gravitational forces. 2. Analyze each option - **A (ampulla):** Part of the semicircular canals involved in detecting rotational movement. - **B (vestibule):** Contains the utricle and saccule, crucial for detecting linear acceleration and gravity. - **C (cochlea):** Involved in hearing, not balance. - **D (middle ear):** Transmits sound vibrations; not directly involved in balance. - **E (tympanic membrane):** Also known as the eardrum, involved in hearing, not balance. 3. Determine correct options Based on the analysis, the structures involved in equilibrium and balance are the ampulla and the vestibule.
