Document Summary

*multiple sensory inputs integrated together to give you correcting action of muscles. Oculomotor (iii): muscles moving eyes scan periphery to make sure we are taking in as much info as possible. Accessory (xi): muscles moving head keeps head straight innervates sternocleidomastoid and trapezius. Ganglion cells in fovea: high visual acuity and colour vision: pathway: retina to lateral geniculate nucleus. Ganglion cells in para fovea: motion and direction detection: tuned to be able to pick up motion, superior colliculus. Spinal nerves involved in balance information comes in from proprioceptors coming from deep muscle receptors of. Balance muscles go into the spinal pathway (cid:0) cerebellum in order for coordination of muscle group contractions. Muscles in axial skeleton and 3 muscles in thigh minimize sway brain is able to stimulate these muscles of balance. 2) left and right acceleration: up and down acceleration.
