Document Summary

Studying: how receptors beneath the skin, in the muscles and joints, are used to determine the shape. If the sensors considered here are working, you should see that you are quite accurate. This ability to do so (touch your nose with your finger when your eyes are closed) depends on: 1) proprioception (your sense of limb position, e. g. where your hand is relative to your fore arm. Where your forearm is relative to your upper arm. Where your elbow is relative to your shoulder: also has to know the length of all these structures, 2) kinesthesia (your sense of limb movement) Have to know how fast you are going in order to know when to slow down the movement before you hit the nose. Each receptor type is best at indicating a particular attribute: spindles: signal position and velocity, golgi tendon organs: signal force.
