Document Summary
Sensory feedback from our body about the world around us allows is to adjust ongoing actions. Proprioception: provides info about the state of the body itself. Both types of feedback are inherent/intrinsic feedback. Augmented feedback occurs when the performer is not normally aware (info provided by external source) Vestibular system, gto, cutaneous receptors and muscle spindles. Sensory feedback is critical for skilled voluntary actions. Cutaneous receptors: critical for haptic sense, includes several kinds of specialized detections of pressure, temperature and touch. Tactile inputs from the motor periphery are important. With normal sensibility and full vision= full hand function. With fingertip anesthetic and full vision= difficulty with object manipulation. We receive tactile info from motor periphery. Sensory feedback from cutaneous receptors is critical for normal arm and hand function. Cutaneous mechanoreceptors: sense organ that responds to mechanical stimuli such as stretch, pressure or vibration.
