Pap test. The Papanicolaou test (abbreviated as Pap test, known earlier as Pap smear, cervical smear, or smear test) is a method of cervical screening used to detect potentially pre-cancerous and cancerous processes in the cervix (opening of the uterus or womb). Pap smear is performed by opening the vaginal canal with a speculum, then collecting cells at the outer opening of the cervix at the transformation zone (where the outer squamous cervical cells meet the inner glandular endocervical cells).
In English, the exact term is an offshoot of the phrase, wall of separation between church and state, as written in Thomas Jefferson's letter to the Danbury Baptist Association in 1802. In that letter, referencing the First Amendment to the United States Constitution, Jefferson writes:
In brief he: â¢ Invented the first electric battery â which people then called the âvoltaic pileâ â in 1800. Using his invention, scientists were able to produce steady flows of electric current for the first time, unleashing a wave of new discoveries and technologies. â¢ Was the first person to isolate methane.
