What is the length of poio vaginalis in centimeters?
The cervix, also called the poio vaginalis, is somewhat barrel-shaped and is 2-4 cm in length, its lower end joining the vagina at an angle varying from 45-90 degrees. The cavity of the cervix is fusiform in shape, with longitudinal folds or furrows. Must Know: The endocervical canal is composed of columnar, mucus-secreting cells, whereas the external cervix is lined by nonkeratinizing squamous epithelium. The junction between these 2 areas is called the squamocolumnar junction or transitional zone. Ref: Heitmann R.J. (2013). Chapter 1. Anatomy of the Female Reproductive System. In A.H. DeCherney, L.
