Detects the position and the motion of the body in space 1 of 15 How does the vestibular system work? By integrating information from peripheral receptors located in the inner ear 2 of 15 What are the two main components of the vestibular system? Semi circular canals and vestibular sacs 3 of 15 What are the two vestibular sacs? Saccule and Utricle 4 of 15 what do the semi circular canals respond to? Acceleration of the head or body due to gravity 5 of 15 what is the push-pull system? the semi circa canals work in pair; when one is stimulated the other is inhibited 6 of 15 What is the vestibulo-occular effect? signals from the semi-circ canals are sent as directly as possible (10ms) to the eye muscles 7 of 15 what is the three neurone arc? How info from the right semi circ canal travels 8 of 15 How does info from the right semi circa canal travel? Vestibulocochlear nerve, vestibular nucleus, abducens nucleus, oculomotor nucleus 9 of 15 what do vestibular sacs detect? linear acceleration of the head 10 of 15 what are otoliths? calcium carbonate crystals, get displaces and produce signal 11 of 15 Utricles detect what? forward/backward motion of the head and eye movements 12 of 15 Saccules detect what? vertical motion of the head 13 of 15 Where are the vestibular nuclei? Medulla 14 of 15 Be able to label the medulla 4 vestibular nuclei superior, lateral, medial, inferior 15 of 15
