"When this sense is working effectively the brain, at all times, has an awareness of where the various body parts are in space, if they are moving or not, and how fast and in what direction they are moving...We talk about this sense enabling us to ‘feel’ where our body parts are, but this does not mean ‘feeling’ like ‘touching’ one body part with another – it is an entirely internal sensation".
