Mydriasis pupil) or overactivity of the sympathetic nervous system (SNS). Pupil diameter also increases in reaction to cognitive tasks requiring memory and attention, and this phenomenon is used as an indicator of mental activation (‘arousal’) in psychophysiological experiments . Natural release of the hormone oxytocin can cause mild to moderate mydriasis. Parasympathetic fibers travel with cranial nerve III, the oculomotor nerve, to innervate the circular layer of muscle of the eye (sphincter pupillae). Damage to this nerve typically manifests itself as mydriasis, because the sympathetic supply to the pupil, which causes mydriasis, remains unaffected, and therefore unopposed.

Widening participation Widening participation Widening participation (WP) in higher education is a major component of government education policy in the United Kingdom and Europe. It consists of an attempt to increase not only the numbers of young people entering higher education, but also the proportion from under-represented groups (those from lower income families, people with disabilities and some ethnic minorities).
