How big is your urethra?
How big can a urethra get? In the human male, the urethra is on average 18 to 20 centimetres (7.1 to 7.9 in) long and opens at the end of the external urethral meatus. This is the intramural part of the urethra surrounded by the internal urethral sphincter and varies between 0.5 and 1.5 cm in length depending on the fullness of the bladder.
Is 8mm the average size of the meatus?
The sigmoid curve of the male urethra necessitates the use of a special maneuvre during dilatation. 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 Female Urethra?
The female urethra is the part of the female urinary system. It has developed from the endoderm and the splanchnic mesoderm of the urogenital sinus. The paramesonephretic tubercle divides the urogenital sinus into pelvic which will later become a vesicourethral unit and a phallic portion which later becomes a vagina. Female urethra develops in the 12 th gestational week. The female urethra is relatively a simple tubular structure that has the only purpose of urination. It is a short organ without complex investing structure. It is a richly vascular spongy cylinder and is designed to provide continence. Although female urethra less prone to intrinsic pathology as compared to male urethra but infection can be started because of its short length. Urethritis is common inflammation of the urethra. It also causes painful urination. Urethritis can also be caused by viral and bacterial infections. Its symptoms are urgent urination and pus like excretions and discharges. Treatment of urethritis depends on the exact causes and symptoms but mostly involve different types of medicines. Kidney stones is another disease that strikes female urethra.
What is the third part of the urethra?
The third part of the male urethra is membranous urethra which is a small portion passing through the external urethral sphincter and almost 1 to 2 cm in length. This is the smallest in diameter part of the urethra. It is present in the deep perineal pouch. The bulbourethral glands and found posterior to this region but open in the spongy urethra.
What is the first part of the bladder?
First part is pre-prostatic urethra which is intramural part of this organ and about 0.5 to 1.5 cm in length depending on the fullness of the bladder. Its second part is prostatic urethra which crosses through the prostate gland.
What is the difference between a male and female urethra?
The male urethra is larger in length than female urethra. Another difference would be th path the urine takes getting from the bladder to the external world. In males the path is more curving and in females the path is more direct. This curved path makes catheterization of males more difficult. Due to the short length of the urethra in females, infection can be a problem.
What causes urination and pus?
Urethritis can also be caused by viral and bacterial infections. Its symptoms are urgent urination and pus like excretions and discharges. Treatment of urethritis depends on the exact causes and symptoms but mostly involve different types of medicines. Kidney stones is another disease that strikes female urethra.
How long is a male urethra?
The main difference between Male Urethra and Female Urethra is in length. In males urethra is 8 inches long, and in females urethra is only 2 inches long. Male urethra has differentiated into four parts while female urethra has no differentiation.
Which gland is located posterior to the penis?
The bulbourethral glands and found posterior to this region but open in the spongy urethra. Its fourth part is spongy urethra which runs along the length of the penis on its ventral surface. It is almost 15 to 16 cm in length and travels through the corpus spongiosun. The duct from the urethral gland enters here.
What is Male Urethra Anatomy?
The male urethra anatomy is totally dependent on the function and structure of the male urethra. Male urethra involves in performing two functions. They are the transport of urine to the exterior and the transport of semen to the exterior. Because of its additional function, the male urethra has a length of 20 cm. Its diameter is about 8 – 9 mm. Furthermore, stratified and transitional columnar epithelia line the urethra . Also, the male urethra has an external sphincter, which functions as a voluntary control. Striated muscle lines this external sphincter.
What are the Similarities Between Male and Female Urethra Anatomy?
Male and Female Urethra is used in the excretion of urine to the exterior.
How many parts does the male urethra have?
Moreover, the anatomy of the male urethra contains four parts. Pro – prostatic urethra: This is in the length of 0.5 – 1.5 cm and is the intramural part of the male urethra. Prostatic urethra: This is the second part that crosses the prostate glands in the male. Membranous urethra: The third part, which is the small opening.
What is the difference between a male and female urethra?
The key difference between male and female urethra anatomy is that the male urethra is longer while the female urethra is shorter in structure. Also, unlike female urethra, the male urethra is a complex structure and has subparts. In Anatomy, urethra refers to the functional duct, which is responsible for transporting urine from the bladder to ...
How long is the female urethra?
We can explain the female urethra anatomy by its short structure. The length of the female urethra is about 4 cm and the diameter is about 6 mm. It has a shape of a simple tubular structure. Also, the female urethra has no subparts in comparison to male urethra. Figure 02: Female Urethra.
What is the third part of the urethra?
Membranous urethra: The third part, which is the small opening. It is of length 1 – 2 cm. It locates in the deep perineal pouch. Spongy urethra: The final part of the urethra that lies along the length of the penis. It is about 15-16 cm in length. Prostatic plexus supplies the nerve to the male urethra.
Which plexus supplies the nerve to the male urethra?
Prostatic plexus supplies the nerve to the male urethra. Thus, this contains both sympathetic and parasympathetic functions. In terms of urethral infections, females are more prone to infections compared to males since female urethra directly exposes to the environment.
What are the main urethra disorders?
Due to anatomical variations of the urethra, genetics, or external factors, such as suffering an injury, there are a few main urethra disorders: 8 ?. Urethra cancer. Urethral strictures: A narrowing of the urethra tube. Urethritis: Inflammation of the urethra caused by infection.
What are the parts of the urethra?
Anatomy. The male urethra is divided into three parts: the prostatic urethra, membranous urethra, and the spongy urethra. The prostatic urethra starts at the neck of the bladder and is located in the prostate. This is typically the widest part of the urethra, which then connects to the membranous urethra, found in the urogenital diaphragm.
How long is the urethra?
The urethra is a thin tube that connects to the bladder in order to empty urine out of the body. The female urethra is short, about 1.5 inches long, while the male urethra is longer at 7 to 8 inches in length as it runs length of the penis. 1 ? The male urethra not only carries urine out of the bladder, but it also transports semen.
How does the brain tell the bladder to release urine?
This is done when the brain tells the bladder when it’s time to squeeze and the sphincter muscle to relax, releasing urine through the urethra. 6 ? This same mechanism is used in males when they ejaculate and sperm is carried through the urethra.
Why is my urethra not working properly?
There are a few congenital (present at birth) conditions that may cause the urethra to not work properly, leading to infection and other issues. These include the urethra not being in the right place (clinically referred to as hypospadias ).
Which artery is used for the prostatic urethra?
The prostatic urethra uses the inferior vesical artery (found in the pelvis near the lower bladder), the membranous urethra uses the bulbourethral artery (located in the bulb of the penis), and the spongy urethra uses the pudendal artery, found deep in the pelvis. 3 ?.
