Mouth of womb
The ostium uteri, or mouth of the womb, is bounded by two lips, anterior and posterior (labium anterius and labium posterius). The posterior lip is thinner and projects downward less than the thicker anterior lip. It also appears longer because the vagina is attached to it at a higher level than to the anterior lip. The mucous membrane is smooth and is devoid of folds in the cavity of the uterine body but forms palmate folds, arbor vitae (plicae palmatae) in the cervical canal, which consist of an anterior and a posterior longitudinal ridges and a series of lateral rugae directed laterally and upward.Medical coding training india will train all these.
