urethra, duct that transmits urine from the bladder to the exterior of the body during urination. The urethra is held closed by the urethral sphincter, a muscular structure that helps keep urine in the bladder until voiding can occur.
Where is the urethral orifice located?
Description. The male external urethral orifice is the external opening or urinary meatus, normally located at the tip of the glans penis, at its junction with the frenular delta.
Where is urethral orifice located in a female?
Anatomy and function of the female urethra This is a muscular structure in the urethra that helps hold urine inside the body until it’s released. The urethra opens into the vestibule, the area between the labia minora. The urethral opening sits just in front of the vaginal opening.

The male urethra can subdivide into four parts, each part containing unique gross and histological features.
- Pre-prostatic urethra. Location: Extends inferiorly from urinary bladder and ends prior to entering the prostate gland.
- Prostatic urethra.
- Membranous urethra.
- Spongy urethra.
What’s a mans pee hole called?
urethral meatus
From your two kidneys, two ureters move the urine to the bladder, where it’s stored until you urinate (pee). Urine leaves your body through a hole at the end of your urethra. That hole from the inside to the outside is called the urethral meatus. (The term ‘meatus’ refers to any opening from the inside to the outside.)
What is the difference between meatus and orifice?
The external urethral orifice is the external opening (or meatus) of the urethra. It is where urine exits in both males and females. In males, it is also where the semen is ejected during ejaculation. The male external urethral orifice is located on the glans penis, at the tip, at the junction with the ferenular delta.

How wide is a man’s urethra?
The male urethra is 8 – 9 mm in diameter. The external meatus is 8 mm in size, but normally appears as a vertical slit. The portion of the urethra immediately behind it, in the glans, is 10 — 11 mm in diameter.
What is the difference between ureteral orifice and vesicoureteric junction?
It is nearly synonymous with ureteral orifice ( UO ), although depending on the context, the VUJ could include a small amount of the distal most ureter, whereas the UO is limited to the opening from the ureter into the bladder only. The vesicoureteric junction inserts at an angle into the bladder trigone.
What is the opening of the urethra called?
The opening of the urethra at the tip of the glans is called the urethral meatus. The last portion of the urethra after the penile urethra through which the urine travels before reaching the tip (urethral meatus) is the part within the head of the penis. The urethra anatomy term someone gave to this part of the urethra is “fossa navicularis”.
