Usually we think that there are five senses vision (sight), audition (sound), olfaction (smell), taction (touch), and gustation (taste). These senses are responsible for our interaction with the external world. In addition to these External senses there are few senses tat are called "Internal Senses". One of the most important internal senses is called "proprioception", or position sense.
Proprioception allows humans to control their limbs without directly looking at them.
Pathway For Proprioception:
Muscle Spindle & Golgi Tendons-------------->>> Dorsal Root Of Spinal Cord----------->>>> Spinal Cord-------->>>>> Spinocerebeller Tract------->>>>> Cerebellum
The cerebellum accepts information from every muscle and joint in the body, and calculates where the limbs must be in space.Like most physiological processes, proprioception can be improved with challenging practice, and can also be impaired by disease or disuse.Proprioception is also impaired by diseases or injuries affecting the musculoskeletal system, like an ankle sprain or diabetic neuropathy. Patients suffering from these types of conditions are predisposed to falls and repeat injuries, which compounds problems.
