. The anatomy and physiology of the human body. Containing the anatomy of the bones, muscles, and joints; and the heart and arteries . ncter muscle : but it is wider within,and where it receives the orifice of the womb. It may bedistended to almost any degree, but naturally its sides, bytheir own elasticity, the fulness of the veins which are uponit, and the contraction of the surrounding fibres, are in contact. In the natural state, the orifices of the vagina and womb arebut three or four inches distant, often only two; and some-times, where there is a degree of relaxation, they are nearlyin contact. In the first months of pregnancy, the orifice of thewomb is kept down by the degree of difficulty the body of thewomb has in shooting up from the brim of the pelvis. Butthe gravid uterus rising above the pelvis in the latter months,draws up the orifice of the womb and stretches the vagina. The vagina bends gently round the pubis, as it were, orfollows the axis of the pelvis ; and as the interior of the twocircles cut off by the same radii s the sliorter, the vagina islonger behind than before. 220 OF THE VAGINA, & And thus (z?i this fourth plaii) the forepart of the vagina A,is shorter than the backpait B. We may observe from this plan,also, that the orifice of the womb C, projects as it were intothe vagina, so that the finger touches the os tincse, and chieflyits anterior lip, without reaching the upper part of the vagina. The vagina takes its curve nearly in the centre of the pel-vis ; it is of necessity attached by cellular substance to therectum and bladder. The urethra, as we have said, opensabove the orifice, and that canal is attached to the vagina in itswhole length; and the neck of the bladder is attached to theupper part. In consequence of this natural connection, diseaseof the vagina sometimes throws the whole parts, the rectum,vagina, and bladder, into one fistulous ulcer. The vagina has three coats ; that is to say, it has the innercoat, or surface, a f
