What is nervous mechhanisms?
When the sympathetic in the neck is cut, the pupil becomes considerably contracted. Hence, it has been argued that the nerves supplying the dilator are derived from the sympathetic.These fibres are supposed to take origin in the gray matter of the cervical spinal cord. The sympathetic also supplies the walls of the vessels, and thus controls the amount of blood going to the iris and this contraction of the pupil has been explained as due to vascular engorgement. It is argued that though the vasomotor mechanisms may cooperate in dilatation, they cannot be its only cause, as the widening of the pupil may occur in a bloodless eye. Since the other tissues are elastic and antagonize the sphincter, paralysis of that muscle would give rise to dilatation even in anaemic mydriasis.
