CHAPTER I.

THE PELVIS AND GENITAL ORGANS.

The Pelvis is that part of the skeleton found between the lower end of the spinal column and the thigh bones. It consists of four bones, the sacrum, the coccyx, and the right and left innominate or hip bones. These bones form a canal through which the child passes during labor.

Measurements, or Diameters, are taken from certain parts of the pelvis to determine the capacity of this canal. It is important that every pregnant woman should have her pelvis measured by the physician whom she expects to have attend her in labor, in order that it may be discovered whether her pelvis is at all under size, so that special precautions may be taken in time to prevent difficulty in the delivery. These measurements should be taken not later than the seventh month of pregnancy, as it may be desirable, for the sake of both mother and child, that the physician should induce premature labor.

The Canal of the Pelvis contains the internal organs

of generation, viz., the uterus, Fallopian tubes, and ovaries; and the bladder and rectum besides.

The External Organs are called the "pudenda," or "vulva."

Immediately above the pubic bone, or anterior border of the pelvis, is a cushion of fat, usually covered with hair. This is called the "mons veneris." On each side of the opening of the vulva are the "labia majora," or

large lips. Lying beneath these and concealed by them, in young women, are two thin folds of flesh, named the "labia minora," or "nymphæ." They join together above, and at their junction is a small projecting body called the "clitoris." The small triangular space between the clitoris and the nymphæ is the "vestibule."

The opening of the urethra (the "meatus urinarius”), through which the urine escapes from the bladder, is in the middle of the lower border of the vestibule. It is very important that the nurse should know the exact
