The ampulla of vas deferens, also called the ampulla of ductus deferens, is an enlargement of the vas deferens at the fundus of the bladder which acts as a reservoir for sperm. This structure is seen in some mammalian and squamate species and is sometimes tortuous in shape.

  • 精管膨大部(せいかんぼうだいぶ、英: Ampulla of ductus deferens)は、精管が前立腺に入る末端部で袋状に膨らんだ部分をいう。 内部は小室に分かれており、精嚢と似た構造をとる。精管から運ばれてきた精子は射精直前に一時的に精管膨大部にたくわえられて待機する。精管膨大部の開口部は精嚢と合流して射精管となっている。射精時には精管膨大部の平滑筋が収縮して精子を押し出し、精嚢からの分泌液と混合される。 (ja)

  • L'ampolla del dotto deferente è il tratto terminale dilatato del dotto deferente a livello del fondo della vescica che funge da serbatoio per lo sperma. Questa struttura mammellonata è presente in alcune specie di mammiferi e squamati ed è talvolta di forma tortuosa. La sua parete, come quella di tutto il dotto, è piuttosto spessa. La tonaca muscolare è composta da tre strati: longitudinale esterno, circolare intermedio e un altro strato longitudinale più internamente. La tonaca avventizia è costituita da connettivo denso. (it)

  • L'ampolla del dotto deferente è il tratto terminale dilatato del dotto deferente a livello del fondo della vescica che funge da serbatoio per lo sperma. Questa struttura mammellonata è presente in alcune specie di mammiferi e squamati ed è talvolta di forma tortuosa. La sua parete, come quella di tutto il dotto, è piuttosto spessa. La tonaca mucosa, di colore giallastro, si presenta sollevata in pieghe longitudinali che scompaiono alla distensione del condotto. Queste pieghe a livello dell'ampolla risultano irregolari e permanenti, sono inoltre variamente anastomizzate tra loro e formano cripte. L'epitelio di tipo cilindrico nell'ampolla non presenta le stereociglia del tratto precedente. La tonaca propria è ricca di fibre elastiche. La tonaca muscolare è composta da tre strati: longitudinale esterno, circolare intermedio e un altro strato longitudinale più internamente. La tonaca avventizia è costituita da connettivo denso. (it)
