We maintain our balance by these ways: 1. Visual; we will be able to keep our balance by interpreting the visual perception in the visual cortex and then associating it to area 40. From here, the "total interpretation" will result in activation of motoric cortex and then from here the information passed through cerebellum (center of balance)to our motoric organs (muscles of the limbs) 2. Vestibular; movement of endolymph inside our vestibule of inner ear will result in reposition of otoliths that are located in macula sacculi & macula utriculi. This event will cause end-receptor of these sensing apparatus stimulated and the impulse will eventually reach the centre of balance and the subsequent events will be similar to the aforementioned. 3. Proprioception; There is a kind ok neuronal receptor which is located in the joint that monitor the change of body position time after time. The change of body position such as in walking will cause the stimulation of joints of knees hips, elbows, shoulders,and this information will be sent through proprioception tract which is located in the dorsal column of spinal cord named columna dorsalis. The subsequent events will be similar in some ways to the afore mentioned. Ref: Guyton & Hall. TEXTBOOK OF MEDICAL PHYSIOLOGY, 10th ed.
