What is vertigo?
Vertigo is a term commonly used to describe various sensations of dizziness. The technical definition of vertigo refers specifically to the perception of motion when there is no actual movement. Vertigo occurs due to a disturbance in what’s known as the vestibular system. The vestibular system is responsible for telling our brain when our head is moving and it allows us to keep our vision steady during movements. For example, when we are walking, the vestibular system is what allows us to turn our head to the left while keeping our eyes forward so we don’t fall over.
The vestibular system is a sensory apparatus that lies within the inner ear, which is why you may have heard people say that your ears are responsible for your balance! The inner ear is located within the bony labyrinth of the temporal bone and contains the cochlea, semicircular canals & the otolith organ.
