The bending of the right knee when reverencing the altar and at other times of solemn reverence. Episcopalians sometimes bow instead of genuflecting.

Genuflection is an act of reverence consisting of falling onto (usually) one knee. Today the term is used mostly in the Latin rite of the Roman Catholic Church and in churches of the Anglican Communion. The faithful who pass before the presence of the Blessed Sacrament (generally reserved in the tabernacle) are expected to genuflect on the right knee as a sign of devotion.
