| The segmentation is meroblastic, and the germinal disc adjoins the opening of the oviduct. |
| Finally, Dr. Edwards has developed a monoclonal antibody to the chicken oviduct progesterone receptor. |
| The ovary was grasped with a hemostat, a ligature was placed around the oviduct and blood vessels, and the ovary was removed. |
| During a 20 hour passage down the oviduct, the egg becomes surrounded by albumen, the shell membranes, and the shell. |
| In a few species, immature eggs that enter the oviduct are eaten by the developing young. |
| A thin shell membrane forms in the part of the oviduct known as the isthmus. |
