Flow of urine from the catheter confirms placement. Embryologically, the perineum is formed by the connective tissue that separates the anal membrane dorsally from the urogenital membrane ventrally. G.Y. Railroads. This ring oftentimes is incompetent (weak or incapable of closing) when pneumovagina exists, allowing entry of air into the vaginal space. vestibule of aorta a small space within the left ventricle at the root of the aorta. In the maculae, the receptors rest low on an ill-defined basement membrane and have calcium carbonate concretions (otoconia) that stain light blue to pink and are roughly spherical masses overlying the gelatinous otolithic membrane (Fig. This lesson provides an important overview of the major male and female reproductive structures, functions, and hormones.

The transverse frenular fold, arising from the vestibular mucosa, forms the roof of the prepuce and is attached to the glans clitoridis by a median frenulum. Imaging (radiography or ultrasonography or both) can be used if placement is still in question. The vestibule surrounds the opening of the vagina, or introitus, and the opening of the urethra, or urethral meatus. The information furnished by the vestibular system is also essential for coordinating the position of the head and the movement of the eyes.

This embryonic structure later develops into the perineal body, which is a node of muscular and fibrous tissue between the anus and the vestibule. It is located between the semicircular canals and the cochlea. The vestibule generally occupies a median position in the pelvic outlet and extends from the external vulvar lips to the transverse fold (approximately 10–12 cm in length) that often lies over the urethral orifice, caudal to the fold (see Fig. The gums (gingivae) are paler pink and fit … Learn more about external genital development and find out how and when the tissue changes.
