sense (also called proprioception or kines-thetic sense) was discussed and will
be reviewed only briefly here. Stretch receptors (also called proprioceptors or
muscle spindles) detect stretching of muscles and generate impulses, which
enable the brain to create a mental picture to know where the muscles are and
how they are positioned. Conscious muscle sense is felt by the parietal lobes.
Unconscious muscle sense is used by the cerebellum to coordinate voluntary
movements. We do not have to see our muscles to be sure that they are
performing their intended actions. Muscle sense also contributes to our ability
to distinguish the shape of objects.
