The middle part of the ureter is supplied by the common iliac arteries, direct branches from the abdominal aorta, and gonadal arteries; [1] the gonadal arteries being the testicular artery in men and the ovarian artery in women. [2] The lower third of the ureter, closest to the bladder, is supplied by branches from the internal iliac arteries ...

The neck of the bladder is the area at the base of the trigone that surrounds the internal urethral orifice that leads to the urethra. [5] In males, the neck of the urinary bladder is next to the prostate gland. The bladder has three openings. The two ureters enter the bladder at ureteric orifices, and the urethra enters at the trigone of the ...
The urinary meatus [a] (/ m iː ˈ eɪ t ə s /, mee-AY-təs; pl.: meati or meatuses), also known as the external urethral orifice, is the opening of the penis or vulva where urine exits the urethra during urination. It is also where semen exits during male ejaculation, and other fluids during female ejaculation. The meatus has varying degrees ...
The two Skene's ducts lead from the Skene's glands to the vulvar vestibule, to the left and right of the urethral opening, from which they are structurally capable of secreting fluid. [2] [3] Although there remains debate about the function of the Skene's glands, one purpose is to secrete a fluid that helps lubricate the urethral opening. [2] [3]
Structures opening in the vulval vestibule are the urethra (urinary meatus), vagina, Bartholin's glands, and Skene's glands. [1]The external urethral orifice is placed about 25–30 millimetres (1–1.2 in) [2] behind the clitoris and immediately in front of that of the vagina; it usually assumes the form of a short, sagittal cleft with slightly raised margins.
