Eye and ear physiology

Use  {{Eye and ear physiology|state=collapsed}}  or  {{Eye and ear physiology|state=uncollapsed}}  to include the template so that it initially displays in, respectively, its collapsed (hidden) or uncollapsed (expanded) state.
Use  {{Eye and ear physiology|state=autocollapse}}  to collapse the template only if there is another template of the same type on the page.
