Position.—The empty female bladder lies behind the pubis and in frontof the vagina, and consists of the urethra and bladder proper. The urethra is a straight slit (some describe it as sigmoid) about Ifinches long, with thick walls closely incorporated with the anterior vagi-nal wall behind. It runs parallel to the plane of the pelvic brim. Its.

On section and microscopi-cal examination, its mucous membrane is found covered with squamousepithelium in its lower part; while higher up it is like that of the bladder,and is very rich in elastic fibres. There is a double layer of unstripedmuscular fibre, the longitudinal layer being internal and the circular out-side ; and, according to Uffelman, a circular (inner) and longitudinal layerof striped muscle, which stretches from the neck of the bladder to within1£ cm. of the meatus urinarius.
