The sense of equilibrium (balance) is coordinated between the vestibular pathways of the inner ear, neural control of eye movement and feedback loops from the muscular sense of proprioception. These three systems are synthesised within the brainstem and multiple structures of the cerebellum and cerebrum.
The inner ear, aside from hearing, is home to sensory receptors involved in receiving information about the spatial position of the head and neck, and relaying these signals to the extraocular eye muscles to keep vision stable. Tiny in scale, embedded within the petrous temporal bone of the human head, the inner ear is neither visible or easily accessible via dissection.
Essential to understanding of the inner ear is the difference in fluid filled structures containing either endolymph or perilymph.
It is hoped that this resource benefits learning and clinical practice, inspiring further investigation into the connections between sensory systems.
