Female Reproductive Anatomy
The female reproductive system consists of various organs that work together to facilitate reproduction. Accessory ducts are a part of this system and include organs like oviducts, uterus, vagina, and cervix.

Role of Cervix
The cervix is a crucial part of the female reproductive system, located at the lower end of the uterus. It acts as a barrier between the uterus and the vagina, protecting the internal reproductive organs from infections and foreign bodies. The cervix also plays a role in facilitating the passage of sperm into the uterus during intercourse.

Exclusion of Cervix from Female Accessory Ducts
- Function: The cervix primarily serves as a protective barrier and a passage for sperm, rather than a duct for the transport of ova or embryos. This is why it is not classified as an accessory duct.
- Structural Differences: Unlike oviducts, uterus, and vagina, the cervix does not have a direct role in the transport or storage of ova or embryos. Its structure and function are more focused on providing support and protection to the internal reproductive organs.
- Developmental Origin: During embryonic development, the cervix arises from a different embryonic tissue layer compared to the other accessory ducts. This difference in origin contributes to the distinct functions and characteristics of the cervix compared to the other ducts.

Conclusion
In summary, the cervix is excluded from the list of female accessory ducts due to its specialized role as a protective barrier and passage for sperm, as well as its distinct developmental origin and structural differences from other ducts in the female reproductive system.

Cervix is also the one of female accessory ducts
