VESTIBULAR SYSTEM Meaning and
Definition
-
The vestibular system is a sensory system in the human body responsible for providing information about balance, spatial orientation, and head position. It comprises a complex network of structures located in the inner ear, which includes the vestibular organs: the semicircular canals and the otolith organs.
The semicircular canals are three fluid-filled tubes arranged orthogonally to each other and are responsible for detecting rotational movements of the head. Each canal is filled with tiny hair-like structures that bend when the head moves and send signals to the brain regarding the direction and speed of the movement.
The otolith organs, consisting of the utricle and saccule, sense linear accelerations and the effects of gravity. These organs contain tiny crystalline structures called otoliths that move in response to gravity or changes in head position. When the head moves, the otoliths bend the hair cells, sending signals to the brain about the body's orientation and position in space.
The information from the vestibular organs is processed by the brain, specifically the vestibular nuclei, and then integrated with visual and proprioceptive inputs to maintain balance, coordinate movements, and control eye movements. The vestibular system plays a crucial role in maintaining equilibrium, aiding in spatial awareness, and allowing appropriate adjustments of the body to various movements and positions in relation to gravity.

Etymology of VESTIBULAR SYSTEM
The word "vestibular" comes from the Latin word "vestibulum", which means "entrance hall" or "forecourt". In anatomy, the vestibule refers to a space or chamber at the entrance of a structure. The word "system" refers to a group of organs or structures that work together to perform a specific function. Hence, the term "vestibular system" refers to the set of organs and structures involved in the sense of balance and spatial orientation.
