Document Summary

*keep the body"s com over the feet balance. *regulate postural reflexes and involved in tonic activation. Vestibulospinal tracts (vestibular nuclei s. c. ) i. n. Example: stepping on a toy with wheels lose balance. Vestibulospinal tract posture responses from axial and proximal muscles. Rubrospinal tract postural responses from proximal muscles. Comprised of: peripheral receptors; labyrinth respond to acceleration. 2 otolith organs respond to linear acceleration; gravity pull movement head movement. Nystagmus: repetitive eye movements where a slow eye rotation is followed by a fast eye repositioning (spontaneous pathology) Most info m. n. of s. c. (vestibulospinal and vestibulocervical) Slow eye rotation direction of rotation. Fast eye repositioning opposite direction of rotation. Head tilt 30 degrees forward for the best horizontal stimulation. Think stirring coffee - if you s*r then let go of the stirrer then it"ll keep spinning so when you spin then stop, the fluid doesn"t stop immediately - keeps going & pulls on the hair cells.
