Diagrams, models and skull preparations are used to describe the vestibular apparatus. The semicircular canals, saccule and utricle are described as well as

The major sensory organs of the vestibular system are located next to the cochlea in the inner ear. These include the utricle, saccule, and the three semicircular 

Namely, the vestibular nuclei are: The superior vestibular nucleus (of Bechterew) There are four 2nd order vestibular nuclei: the inferior, medial, lateral (Deiter’s) and superior vestibular nuclei. All four nuclei are found beneath the floor of the fourth ventricle in the medulla and pons, lateral to the sulcus limitans. The vestibular nuclei then pass the information on to a variety of targets, ranging from the muscles of the eye to the cerebral cortex. What is the vestibular system and what does it do?

Martha Bagnall, The vestibular nuclei comprise several subdivisions (see Chapter 29) and are Vestibular System. The spinal vestibular The vestibular portion of the eighth cranial nerve informs the brain about the linear and angular movements of the head in space and the position of the head with respect to gravity.

This vestibular nucleus excites the contralateral abducens nucleus which innervates the right lateral rectus muscle through the sixth cranial nerve. The contraction of the right lateral muscle occurs. It also sends a signal to the ipsilateral oculomotor nucleus, which innervates the medial rectus muscle through the third cranial nerve.

The four cellular masses in the floor of the fourth ventricle giving rise to a widely dispersed special sensory system. Included is the superior, medial, inferior, and LATERAL VESTIBULAR NUCLEUS. (From Dorland, 27th ed) The four nuclei are: medial (Schwalbe's) vestibular nucleus largest of the vestibular nuclei lateral and superior to the nucleus ambiguus and largest of the vestibular nuclei lateral and superior to the nucleus ambiguus and dorsal vagal nucleus extends from the level of the upper olive to the 2021-02-16 · The vestibular nuclei are structures in the brains of mammals that are part of the vestibular system, which provides the organism with its sense of balance and awareness of the body's orientation in space. The vestibular nuclei are located in the fourth ventricle.

The majority of neurons ( 2/3) were sensitive to vestibular stimulation but not to eye move-ments. During the vestibular-ocular reflex (VOR), these neurons discharged in a manner comparable to the “vestibular only” (VO) 2021-04-08 · The vestibular nuclei are aligned within the rhomboid fossa in such a way that they form two vertical columns, one medial and one lateral.
