Urethra
The part of the urethra within the urogenital diaphragm is called the membranous urethra. It is a short segment of the urethra that passes through the urogenital diaphragm, which is a sheet of muscle and connective tissue located between the pelvic cavity and perineum.
The portion of the urethra between the prostate and penis is called the membranous urethra. It is a short segment located in between the prostatic and spongy parts of the urethra. It passes through the urogenital diaphragm before continuing through the penis.
The narrowest part of the male urethra is the external urethral meatus, which is the opening at the tip of the penis where urine and semen exit the body. It is the most constricted part of the urethra and can be prone to blockages or infections.
the work of the urethra is to help the bladder to hold the urine
In my experience none at all. Some people get infections but I have had no issues with anything like that in all my years of playing.
the urethra transport urine from the bladder :-)
Transitional epithelium is found in areas that are subject to considerable stretching. Tissue in the bladder, urethra, ureters, an prostate often expand and contract.
Urethra Gauge The Urethra must be measured with a tool called, "Urethra Gauge" this device takes the guess-work out of determining the sizing for urinary catheters.
cause it does
Stratified transitional epithelium can typically be found lining areas of the body that are subject to stretching or expansion, such as the urinary bladder, ureters, and parts of the urethra.
Stretching doesn't make you tired, it's actually the opposite. Stretching is your body's reaction to being tired, stretching is its way of trying to put your muscles to work and wake you up.
The tissue situated in the lining of the urinary bladder and urethra, where stretching occurs, is called transitional epithelium. This specialized type of epithelial tissue is capable of expanding and contracting, allowing it to accommodate varying volumes of urine. It features cells that can change shape, typically appearing cuboidal when the bladder is empty and more flattened when it is full. This adaptability is crucial for the bladder's function in storing urine.
The work done by the stretching body is equal to the difference in potential energy stored in the spring before and after it is stretched. This work is done against the restoring force of the spring.
