Vestibular refers to the perception, balance, and movement of the body within space. Its antonyms, on the other hand, can be described as words that represent the lack of these elements. Some antonyms of vestibular include non-movement, non-spatial, non-sensory, non-perception, and non-balance. These antonyms can be used to describe situations where an individual may lack the ability to perceive and move around their environment. This may be caused by various factors such as illness, injury, or congenital defects. Although vestibular means being in-tune with one's surroundings, antonyms provide a valuable contrast to better understand the concept of vestibular.
