| ♦ | A08.3.01.027 | Ostium urethrae internum This term describes the opening of the urethra from the bladder. However, superimposed lateral cystograms and voiding cystourethrograms show that the ostium in the bladder that is filling differs from the ostium in the bladder that is voiding. The bladder around the ostium urethrae accipiens usually forms a flat disc or baseplate, the pars intramuralis urethrae (bladder neck) is closed and the urethra is at its longest. With the onset of voiding the baseplate becomes progressively funnel-shaped and the bladder neck opens and becomes incorporated into the funnel so that the bladder appears to descend and the urethra to shorten. The ostium urethrae internum evacuans then lies some 20% closer to the ostium urethrae externum in the female, and at the basis prostatae in the male. |
| ♠ | A08.3.01.027 | Ostium urethrae internum The two entries for this entity were made identical by adding the English synonym internal urinary meatus to the entry that did not already have it. |
| ♠ | A09.4.02.016 | M. sphincter urethrae externus The two entries for this entity were made identical by using the male gender symbol in both entries. |
| ♦ | A09.4.02.017 | Pars intermedia With the abandonment of the term urogenital disphragm, pars membranacea has become a misnomer, it being the part between the pars prostatica urethrae and the pars spongiosa urethrae and not just the part passing through the membrana perinealis. The isthmus urethrae extends between the membrana perinealis and the distal end of the colliculus seminalis that may be 0-1 cm above the apex of the prostate. Myers R. P. 1991.
