hellew. Two of my lecture pages are contradicting eachother. I shall type the exact words it says.
on one lecture page it says:-
"dilator pupillae - smooth muscle arranged radially- stimulation of sympathetic fibres---> contraction of radial muscle---->dilation of pupil = mydriasis.
but on another lecture page it says:-
atropine (tropicamide) - passive mydriasis (loss of mitotic drive to constrictor pupillae)
is mydriasis the dilation of pupil or the constriction on pupil?
