A textbook of obstetrics . converted into retention cysts, whichcommonly stud the cervix in cases of old inflammation or in-jury,—the glands or follicles of Naboth. 1 This has long been a disputed point. See Mandl, Ueber die Richtung derFlimmerbewegung im menschlichem Uterus, THE FEMALE SEXUAL ORGANS. 47 The uterine cavity is normally fusiform, widened in its upperpart into a triangular space, most contracted below at the levelof the internal os uteri. It has three openings, the internalos communicating with the cervical canal and the two uterineorifices of the Fallopian tubes. The cervical canal in the nul-liparous woman is a slender ovoid in shape, contracted at itsupper and lower boundaries,—the internal and the external osuteri. In a woman who has borne children the cervical canal isoften funnel-shaped, the external os, or the cavity just above it,being the most expanded portion. The cervix itself is divided into two portions, the vaginal andthe supravaginal. The former projects into the vaginal vault;. Fig- 37-—Section of human uterus, including mucosa [a) and adjacent musculartissue (b) ; c, epithelium of free surface and tubular uterine glands \d) ; f, deepestlayer of mucosa, containing fundi of glands ; h, strands of non-striped muscle pene-trating within the mucosa (Piersol). the latter is attached to the vaginal walls and extends a shortdistance above their attachments. The anatomist commonlyspeaks of the supravaginal portion as being entirely above thevaginal attachments and extending to the isthmus. This view,however, is erroneous, as it assumes that the lower uterine seg-ment is a part of the cervix. It is usual to describe an anterior, shorter lip of the cervix anda longer posterior one. This description is more accurate in theparous woman with a bilateral tear of the cervix. As may beseen in figure 38, the supravaginal portion of the cervix is longeranteriorly than posteriorly. The normal position of the uterus 48 PREGNANCY. is almost horizontal
