{Which of the following statements is correct about the zona pellucida: | |||
|type="()"} | |||
- surrounds the oocyte in the ovary | |||
- protects oocyte in the uterine tube | |||
- is a specialized extracellular matrix | |||
- is important for fertilization | |||

||Yes, the [[Z#zona pellucida|zona pellucida]] has many different functions at different times of oocyte development, fertilization and in the first week of development. | |||
{Pregnancy tests generally are based upon the detection in maternal urine of: | |||

- Estrogen | |||
- Progesterone | |||
- human Chorionic Somatommotropin | |||
+ human Chorionic Gonadotrophin | |||
- human Chorionic Corticotropin | |||
||Estrogen and Progesterone are made in the ovary and support the endometrium. human Chorionic Somatommotropin (or placental lactogen, stimulate maternal mammary development) and human Chorionic Corticotropin are both made by the placenta later in development. | |||

||The '''oocyte''' is present before fertilization, the '''conceptus''' refers to all the products of fertilization and is not a developmental stage, '''polar bodies''' are small exclusion bodies enclosing the excess DNA from oocyte meiosis.
