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.
