Lateral vestibular nucleus
Lateral Vestibular Nucleus
The Lateral Vestibular Nucleus (Pronunciation: Lat-er-al Ves-ti-bu-lar Nu-cle-us) is a cluster of nerve cells located in the vestibular system of the brainstem. It plays a crucial role in maintaining balance and coordinating eye movements.
Etymology
The term "Lateral Vestibular Nucleus" is derived from the Latin words 'latus' meaning 'side', 'vestibulum' meaning 'entrance hall', and 'nucleus' meaning 'kernel'. It refers to the location of this nucleus on the side of the vestibular system.
Function
The Lateral Vestibular Nucleus receives input from the semicircular canals, otolith organs, and the cerebellum. It sends signals to the spinal cord, influencing the activity of motor neurons and thereby controlling the body's posture and balance.
