Document Summary
Chapter 12 spatial orientation and the vestibular system. Vestibular organs: set of 5 organs 3 semicircular canals and 2 otolith organs located in each inner ear that sense head motion and head orientation with respect to gravity: vestibular system or vestibular labyrinth. Spatial orientation: a sense consisting of 3 interacting sensory modalities: the senses of linear motion, angular motion, and tilt. Vestibular organs appeared very early in evolutionary history, and is a fundamental part of the 5 senses. When disturbed, we experience the following problems instability: dizziness: perceived spatial disorientation, with or without, vertigo: sensation of rotation or spinning, spatial disorientation: any impairment of spatial orientation. More specifically, any impairment of our sense of linear m0tion, angular motion, or tilt: imbalance: lack of balance, unsteadiness, nearly falling over, blurred vision, illusory self-motion. Vestibular system usually performs its job automatically without much. Vision and hearing = different modalities, colour and brightness = awareness qualities: difference is in the energy transduced.
