Now to study this law, we need to know clinical function diagram of eye muscles.
So according to this diagram,
Right SR is responsible for elevating right eye to right side.
Similarly, Left IO is responsible for elevating left eye to right side.
Similarly, Left IO is responsible for elevating left eye to right side.
Since both the muscles are performing same action on two different eyes using two different muscles they are called yoke muscles of each other.
This is Hering's law of equal innervation.
This is Hering's law of equal innervation.
Now, here is a trick to solve problem without looking into the diagram:
Right gets converted to Left.
S (Superior) gets converted to I (Inferior)
O (Oblique) gets converted to R (Rectus)
S (Superior) gets converted to I (Inferior)
O (Oblique) gets converted to R (Rectus)
So the mnemonic for remembering muscle change is
ROSI (You can remember it as ROSS from friends!)
R gets converted to O.
S gets converted to I.
R gets converted to O.
S gets converted to I.

On this iron block, one starts to comprehend the distinctions that exist between the separate general sets of laws and their qualities, that is to say, a fundamental contrast in the way of moving toward the issues even in situations where their goals might be same.
