The internal urethral sphincter is a urethral sphincter muscle which constricts the internal urethral orifice. It is located at the junction of the urethra with the urinary bladder and is continuous with the detrusor muscle, but anatomically and functionally fully independent from it. It is composed of smooth muscle, so it is under the control of the autonomic nervous system, specifically the sympathetic nervous system.

  • Le muscle sphincter interne de l'urètre est un faisceau de muscles lisses situé à la jonction de l'urètre et de la vessie. Il est en continuité avec le muscle détrusor de la vessie mais anatomiquement et fonctionnellement totalement indépendant de ce dernier. On trouve dans la littérature de nombreuses autres dénominations : le muscle sphincter de la vessie, le sphincter vésical, le sphincter interne de l’urètre de Henle ou le sphincter lisse de l’urètre (fr)
  • 膀胱括約筋(ぼうこうかつやくきん、bladder sphincter)とは、内尿道口周囲にある平滑筋でに働いている。交感神経である、副交感神経であるに支配される。 収縮(蓄尿)は下腹神経が、弛緩(排尿)は骨盤内臓神経が行う。この膀胱括約筋は解剖学での呼び方で生理学では内尿道括約筋という。 2つの筋肉が含まれており男性では直腸と膀胱の間にある(女性では子宮があるので)と男性では恥骨と前立腺の間にある(女性では恥骨と膀胱との間にあるので)がある。 (ja)
  • O músculo esfíncter interno da uretra é um músculo circular que envolve a uretra em sua porção inicial, próximo a bexiga urinária. Formado por músculo liso, não possui controle voluntário, sua contração garante o armazenamento de urina até que um estímulo adequado promova o esvaziamento consciente da bexiga. (pt)
  • Als Musculus sphincter vesicae („Schließmuskel der Harnblase“) oder Musculus sphincter vesicae internus („innerer Schließmuskel der Harnblase“) wird ein Schließmuskel (Sphincter) am Ausgang der Blase (Ostium urethrae internum) bezeichnet. Der Muskel erscheint als eine Fortsetzung des Musculus detrusor vesicae (Austreiber der Harnblase), ist jedoch bezüglich Anatomie, Funktion und Innervation eine vollkommen eigenständige Einheit. (de)

  • Als Musculus sphincter vesicae („Schließmuskel der Harnblase“) oder Musculus sphincter vesicae internus („innerer Schließmuskel der Harnblase“) wird ein Schließmuskel (Sphincter) am Ausgang der Blase (Ostium urethrae internum) bezeichnet. Der Muskel erscheint als eine Fortsetzung des Musculus detrusor vesicae (Austreiber der Harnblase), ist jedoch bezüglich Anatomie, Funktion und Innervation eine vollkommen eigenständige Einheit. Der Musculus sphincter vesicae spielt eine entscheidende Rolle bei der Harnblasenentleerung (Miktion). Durch Signale des Parasympathikus (über den Nervus pudendus) kommt es zur Erschlaffung des Muskels, wodurch der Blaseninhalt nicht mehr zurückgehalten wird. Umgekehrt führen Signale des Sympathikus zur Kontraktion des Schließmuskels, wodurch die Blasenentleerung verhindert wird. (de)
