        Proprioceptive information is transmitted up the spinal cord in the dorsal columns, majority of the proprioceptive inputs goes to the cerebellum but some passes to the cortex also (conscious Proprioception). There is some evidence that proprioceptive information passes to consciousness in the antero-lateral columns of the spinal cord. Conscious awareness of position of various parts of the body in space depends in part on impulses from sense organ in and around the joints. The organs involved are slowly adapting spray endings, structure that resemble golgi tendon organs, & probably pacinian sorpuscles in the synovia & ligament.
