Document Summary

Balance: ability to keep com over the bos. Eyes, ears, vestibular apparatus, somatosensory system (touch and proprioception), taste, smell. Sensory systems that contribute directly are visual, vestibular and somatosensory. Rods and cones: special nerve ending or sensory receptors in the back of our eyes provide the brain with visual cues that aid in balance. Tell us where our bodies are in space and where we are in relation to other objects. Provides info about the mvt of the head in relation to other objects in the environment. Vision and vestibular system work together by comparing velocity and rotation from the vestibular system with actual visual info. The inner ear organs send signals to the brain about head and body mvts relative to gravity. Endolymph: sacs filled with fluids in the ear. Vestibular apparatus: part of the inner ear that has to do with balance. Composed of 3 semicircular canals utricle and saccule.
