Voorbeelden van ampulla

• Each bony canal contains within it a membranous canal, at the end of which it is dilated to form an ampulla. 

• Swellings at the base of each canal, the ampullae, are visible.

• First seven abdominal terga and sterna with densely and veryfinelyasperate ampullae, those of intermediate segments smaller, that of 7th tergum larger than the others.

• This may seat them further inside the aortic ampulla, but may also deliver more loops into the pulmonary side of the duct.

• The second coil was, therefore, implanted retrogradely with the catheter remaining in the ductal ampulla.

• Coils were positioned insidetheductin the long tubular ducts or straddling the duct (with some loops in the pulmonary artery and some in the aortic ampulla).

• The ductal ampulla was either absent or very small infivepatients, so we implanted a coil which had been cut short.

• Fourthly, the coils can be placed even in patients with a relatively small ductal ampulla.

• When shedding of the oocyte(s) into the ampulla is imminent, stored spermatozoa are activated and released from the caudal isthmus in discrete numbers.

• The oocyte-cumulus complexes in the oviduct were released by breaking the wall of ampullae using a needle.

• The ampulla cytoplasm is an extension of the gland cytoplasm and is rich in cytoplasmic organelles but has few myofilaments.

• The catheter was advanced under fluoroscopic control in the lateral projection to avoid inadvertent entry into the ductal ampulla.

• In six patients (cases 4, 6, 12, 14, 18, and 19), the ductal ampulla was absent, or if present, was very small.

• Whilst reservations here primarily concern epithelial cells prepared from the oviduct ampulla, corresponding reservations would apply to epithelial cells from the isthmus.

• A tear was made in the oviduct near the swollen ampullae.

• After flushing, the oviducts were divided into ampulla and isthmus.
