1. Hering’s law of equal innervation. According to
it an equal and simultaneous innervation flows from
the brain to a pair of muscles which contract
simultaneously (yoke muscles) in different binocular
movements, e.g.:
i) During dextroversion: right lateral rectus and left
medial rectus muscles receive an equal and
simultaneous flow of innervation.
ii) During convergence, both medial recti get equal
innervation.
iii) During dextroelevation, right superior rectus and
left inferior oblique receive equal and simultaneous
innervation.
2. Sherrington’s law of reciprocal innervation.
According to it, during ocular motility increased flow
of innervation to the contracting muscle is
accompanied by decreased flow of innervation to the
relaxing antagonist muscle. For example, during
dextroversion, an increased innervation flow to the
right LR and left MR is accompanied by decreased
flow to the right MR and left LR muscles.
