Which of the following is a region of the male urethra?
The male urethra can be divided into three sections: the prostatic urethra (the uppermost segment within the prostate), the membranous urethra (the segment within the urethral sphincter), and the spongy urethra (the lowermost and longest section within the penis).
What are the four parts of the male urethra?
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 is the smallest region of the male urethra?
The membranous urethra or intermediate part of male urethra is the shortest, least dilatable, and, with the exception of the urinary meatus, the narrowest part of the urethra.
Which hormone is responsible for the development of the urethra?

Which is the correct order of structures in the pathway traveled by sperm quizlet?
From their formation to ejaculation, sperm cells take the following pathway: seminiferous tubule, rete testis, epididymis, ductus deferens, ejaculatory duct, urethra.
How far down the urethra is the prostate?
The prostatic urethra, the widest and most dilatable part of the urethra canal, is about 3 cm long.
What color is your urethra?
The urethra is a narrow tube that connects the bladder with the outside of the body. Urine passes through the urethra. Urethral prolapse occurs when the inner lining of the urethra protrudes through the opening of the urethra. The urethra appears larger than normal and is purple or red and circular.
Where is the male urinary sphincter?
The female or male external sphincter muscle of urethra (sphincter urethrae): located in the deep perineal pouch, at the bladder’s distal inferior end in females, and inferior to the prostate (at the level of the membranous urethra) in males. It is a secondary sphincter to control the flow of urine through the urethra.
Which part of the male urethra is most vulnerable to damage?
Mechanisms of Urethral Injury The distal membranous urethra is especially at risk, and its injury may disrupt the active continence mechanism. The most common injury by far is that of the posterior urethra.
What is the pee hole called?
[u-re´thrah] the tubular passage through which urine is discharged from the bladder to the exterior of the body. adj., adj ure´thral. The external urinary opening is called the urinary meatus.
How wide is male 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 does the urethra do?
The tube through which urine leaves the body. It empties urine from the bladder.
Which structure is the site of sperm production?
The testes are responsible for making testosterone, the primary male sex hormone, and for producing sperm. Within the testes are coiled masses of tubes called seminiferous tubules. These tubules are responsible for producing the sperm cells through a process called spermatogenesis.
What is the urethra function?
Urethra. This tube allows urine to pass outside the body. The brain signals the bladder muscles to tighten, which squeezes urine out of the bladder. At the same time, the brain signals the sphincter muscles to relax to let urine exit the bladder through the urethra.
What is the pathway of a sperm?
The testes are where sperm are manufactured in the scrotum. When ejaculation occurs, sperm is forcefully expelled from the tail of the epididymis into the deferent duct. Sperm then travels through the deferent duct through up the spermatic cord into the pelvic cavity, over the ureter to the prostate behind the bladder.
What is the correct order a sperm must take to exit the male?
What is the correct order of the passage of sperm, starting at the site of development and exiting the body? Initial production occurs in the seminiferous tubules, sperm mature in the epididymis, they then enter the vas deferens, they then pass through the ejaculatory duct and exit the body through the urethra.
Which of the following is the correct order of sperm development?
Thus, the correct order is – Spermatogonia, spermatocyte, Spermatids, spermatozoa.
How can I clean my prostate?

A study involving 3,927 men in Greater Montreal found that drinking a beer every day over a long period is associated with an increased risk of aggressive prostate cancer.
Can you see your own urethra?
The opening to the urethra (the tube that empties the bladder and carries urine out of the body) is not very easy to spot. It’s located below the clitoris, but it’s really small and might be difficult to see or feel — so there’s nothing wrong with your body if you’re having a hard time finding your urethra.
Does urine and sperm come out of the same place?
No. While sperm and urine both pass through the urethra, they can’t come out at the same time.
Why does my urine burn but no infection?
A burning feeling is usually a symptom of a problem somewhere in the urinary tract. Urethral stricture disease, prostatitis, and kidney stones are possible causes of this symptom, and they are all curable. Treatment can often relieve the symptoms of painful bladder syndrome if this is the underlying issue.
Do men have 2 sphincters?
Males have two sphincters: Bladder internal/neck sphincter, smooth muscle is continuous with the detrusor muscle and is under involuntary control or autonomic control; the function of this sphincter is to keep the bladder closed at the time of ejaculation.

The pelvic floor muscle [also known as the pubococcygeus (pu-bo-kak-sij-e- us) or PC muscle] supports your bladder and rectum and helps control your urine flow.
Do men have two sphincter?
Physiology. Male continence is maintained by two sphincters: internal and external. The internal sphincter is part of the bladder neck and is under involuntary or reflex control by higher centers of urination in the brain.
