A sill is an intrusive rock formation. These formations occur when magma solidifies underground and then intrudes into the overlying rock formation. They are distinct from similarly formed domes and dikes because sills are horizontal to the surface.
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).
The Pap test, or Pap smear, is a simple screening test for cancer of the cervix. The cervix is the narrow lower part of the uterus, which forms the opening between the uterus and the vagina.In this test, a few cells are taken from the cervix and sent to the lab to be studied.he Pap test or Pap smear looks at cells taken from the surface of the cervix (the lower end of the uterus or womb connecting the vagina/birth canal to the uterus) during a routine pelvic exam. It screens for cervical cancer and no other gynecological cancer.
