25 下列何者不是副交感神經(parasympathetic nerve)之主要作用?
 控制調焦作用(accommodation) 散瞳(mydriasis)
刺激鼻腔黏液腺(mucous gland)之分泌 刺激淚腺(lacrimal gland)之分泌

answer mydriasis: sympathetics

sympathetic control the radial muscle, thus if contract, it will dilate

parasympathetic controls the circular muscle: thus contract it will constrict
