Perfect for small to medium sized pets. Features include:.The human auditory and vestibular system are critical to maintain balance and orientation. For instance, the vestibular system is responsible for regulating linear and angular movement about the head in the horizontal and vertical planes. In particular, otolith organs, which operate via three semicircular canals in the ear and one saccule, are responsible for determining the body’s linear and angular velocity around an individual’s head. Thus, for the vestibular system to be properly calibrated, the balance of input signals provided from the labyrinth and input from the visual, proprioceptive, and efferent nerve systems must be properly calculated. These systems must work in unison yet operate individually. This process helps to control the body’s balance, as well as, other movement and orientation.
The vestibular system provides afferent (input) neurons to the brain via the vestibular nuclei. The brain processes this sensory information to determine whether to move the body or remain relatively quiescent. At the beginning of a movement, the vestibular system sends signals to move the eyes or limbs of the individual, for instance, through the reticular activating system in turn. Further, otolith sensors detect gravity and linear and angular accelerations. A vestibular nuclei neuron processes the sensory input by comparing the input from each canal and the otoliths. Vestibular nuclei neurons then send efference-type motor neurons to the oculomotor (e.g., the neurons that cause the eyes to move), cerebellum, lateral, and red nucleus to maintain balance and to increase one’s ability to perform other tasks, such as, tracking an object, walking, and even falling asleep. In addition, the vestibular system provides an important sense of linear and angular motion to the brain. For instance, the signals in each vertical canals and other otolith organs are combined to determine an angle of rotation. Further, signals from utricular and saccular receptors and canals are used to determine an amount of angular acceleration and rotation about an axis. As is well understood, these same signals also help maintain stability during changes in the gravitational force.
The vestibular system may also play a role in mediating balance by sensing pressure and accelerations of the body. That is, the inner ear vestibular apparatus serves to convert rotational accelerations of the head in the horizontal and vertical planes into electrical signals that are transmitted to
