Vestibular System Anatomy

The vestibular system which is the system of balance consists of 5 distinct end organs. Activation of distal muscles is primarily the responsibility of the somatosensory system.

The brain uses vestibular input to help it stabilize the head and body in space through neck trunk and hip muscle activation.

Vestibular system anatomy. Anatomy of human inner ear. 3 anatomy 1 good balance is often taken for granted. The vestibular system monitors the motion and position of the head in space by detecting angular and linear acceleration.

Each canal is filled with endolymph and has a swelling at the base termed the ampulla. Vestibular system the vestibular system is the apparatus of the inner ear involved in balance. Half of the membraneous labyrinth the cochlea is dedicated to converting sound waves into neural signals while the other half the vestibular system is dedicated to deriving your sense of balance.

The vestibular system is a system that enables humans to maintain balance and orientation within its three dimensional environment in relation to gravity. The 3 semicircular canals in the inner ear detect angular acceleration and are positioned at near right angles to each other. 3 semicircular canals that are sensitive to angular accelerations head rotations and 2 otolith organs that are sensitive to linear or straight line accelerations.

However with impaired balance such activities can be extremely fatiguing. The peripheral vestibular system is an integral part of the labyrinth that lies in the otic capsule in the petrous portion of the temporal bone. Vestibulo spinal reflex vsr maintains vertical alignment of the trunk.

Both halves use the vestibulocochlear nerve which conducts neural signals to the brain for interpretation and integration. This system allows the body to easily change orientation and maintain balance while making different types of movement simultaneously. Most people dont find it difficult to walk across a gravel driveway transition from walking on a sidewalk to grass or get out of bed in the middle of the night without stumbling.

It consists of two structures of the bony labyrinth the vestibule and the semicircular canals and the structures of the membranous labyrinth contained within them.
