Archive image from page 702 of The cyclopædia of anatomy and. The cyclopædia of anatomy and physiology cyclopdiaofana05todd Year: 1859 Fig. 430. observed to diverge slightly, so as to leave a spindle-shaped canal traversing the whole length of the uterine neck (fig. 431. cc). A second view is obtained by cutting com- pletely through the uterus in the direction of its transverse diameter, and parallel with its extremities. If the entire organ be cut up into many such segments (fig. 427—430.), itis then seen, from the length of the central line, that the cavity varies in breadth, its widest part being in the segment which includes the ex- tremities of the Fallopian tubes ; whilst from this point downwards the line diminishes in length, until at the narrowest portion of the uterus, or that representing the commence- ment of the cervix, it measures only \''— 3'' in diameter. But the most complete view of the interior of the uterus is obtained by a section carried through the centre of the organ, dividing it midway between its anterior and posterior walls. The entire cavity which is thus ex- hibited at one view is seen to be of a trian- gular form ; its boundaries being formed superiorly by the fundus, and on either side by the two lateral borders, whilst in each angle is observed an aperture. The two su- perior openings are the lower orifices of the Fallopian tubes. The inferior opening lead- ing to the cervical canal constitutes the os uteri internum (fig. 431. i). Fig. 431. Series of horizontal sections of the uterus. Fig. 427., just above the entrance of the Fallopian tubes. Fig. 428., in the centre of the cavity. Fig. 429., close to the internal os uteri. Fig. 430., the centre of the cervical canal. The upper or more convex border marks the posterior surface in each section. {Ad Nat,)
