Which structure is primarily responsible for balance alongside hearing?

Balance relies on the inner ear’s vestibular system, with the semicircular canals serving the role most closely tied to sensing head movement. They are three looped tubes filled with endolymph; when the head rotates, the fluid moves and deflects hair cells in the ampulla. This stimulation sends signals to the brain about angular motion, helping to maintain balance and stabilize gaze, in concert with other sensory inputs. The cochlea handles hearing, while the pinna and eardrum are involved in collecting and transmitting sound. The otolith organs in the vestibular system also contribute to balance by detecting linear acceleration and gravity, but they aren’t the structures listed here. So the semicircular canals are the primary structure linked to balance alongside hearing.
