Medial vestibular nucleus
Medial Vestibular Nucleus
The Medial Vestibular Nucleus (pronunciation: ME-dee-al ves-TIB-yoo-lar NOO-klee-us) is a part of the vestibular system in the brainstem that plays a crucial role in maintaining balance and coordinating eye movements.
Etymology
The term "Medial Vestibular Nucleus" is derived from the Latin words 'medius' meaning middle, 'vestibulum' meaning entrance hall, and 'nucleus' meaning kernel or core. It refers to the central part of the vestibular system located medially in the brainstem.
Function
The Medial Vestibular Nucleus receives sensory information from the inner ear and sends signals to the eye muscles and spinal cord to maintain balance and coordinate eye movements. It is particularly involved in the vestibulo-ocular reflex, which allows the eyes to stay focused on an object while the head is moving.
