True or False: Dynamic equilibrium is controlled by sensory hairs within the macula of the utricle and saccule.

True or False: Dynamic equilibrium is controlled by sensory hairs within the macula of the utricle and saccule.

• A. True
• B. False
• C. Conditionally True
• D. Not applicable

Answer: (B)

Dynamic equilibrium refers to the body’s ability to sense and respond to motion, particularly rotational movements. This function is primarily controlled by structures within the semicircular canals of the inner ear, not the macula of the utricle and saccule. In contrast, the macula, which is located in both the utricle and saccule, is responsible for static equilibrium and linear acceleration. It contains hair cells that detect changes in the position of the head relative to gravity or linear movements, but it does not directly contribute to the sensation of dynamic equilibrium. Therefore, the answer is grounded in the distinct roles of different structures in the vestibular system. Dynamic equilibrium relies on the sensory hairs in the semicircular canals, while the macula's function is linked to static equilibrium.
