Papillae on the vestibular floor and walls represent the openings of the branched tubular minor vestibular glands.1,4,6,7,10,11, The vulva is just caudal to the vestibule and consists of two labia and the clitoris. The labia are apposed at the vulvar cleft and form a dorsal and ventral commissure (Fig. answer! If the bladder is empty, flushing and aspirating sterile saline from the catheter can provide evidence of proper placement. The vestibular system is the sensory apparatus of the inner ear that helps the body maintain its postural equilibrium. The vestibule is flushed with 0.5 to 2 ml of a 0.05% chlorhexidine solution five times. If HPV infection is found on the vulva, colposcopy of the vagina and cervix is recommended; if on the anus, proctoscopy. n. 1. The Three Stages of Labor: Dilation, Expulsion & Placental.
