Female Accessory Ducts
Exploration of the oviducts (Fallopian tubes), uterus, and vagina, focusing on their anatomy and roles in reproduction.
What is Female Accessory Ducts?
Paired tubes that transport ova from the ovaries to the uterus and are the usual site of fertilization.
Key points
- Identify and describe the structure of the oviducts, uterus, and vagina.
- Explain the specific functions of each accessory duct in reproduction.
- Locate the site of fertilization within the oviduct.
- Understand the role of these structures in implantation and gestation.
Common exam trap
Confusing the site of fertilization (ampulla) with other parts of the oviduct.
Definitions
- Term
Oviducts (Fallopian Tubes)
- Meaning
Paired tubes that transport ova from the ovaries to the uterus and are the usual site of fertilization.
- Term
Infundibulum
- Meaning
The funnel-shaped, fimbriated opening of the Fallopian tube near the ovary, responsible for capturing the ovulated ovum.
- Term
Ampulla
- Meaning
The wider, middle section of the Fallopian tube where fertilization typically occurs.
- Term
Isthmus
- Meaning
The narrow, medial section of the Fallopian tube that connects to the uterus.
- Term
Uterus
- Meaning
A hollow, muscular, inverted pear-shaped organ in the female pelvis where a fertilized egg implants and develops.
- Term
Endometrium
- Meaning
The inner lining of the uterus, rich in blood vessels, which undergoes cyclical changes during the menstrual cycle and is where implantation occurs.
- Term
Myometrium
- Meaning
The muscular outer layer of the uterine wall, responsible for strong contractions during childbirth.
- Term
Cervix
- Meaning
The lower, narrow part of the uterus that opens into the vagina.
- Term
Vagina
- Meaning
A muscular, elastic tube connecting the cervix to the exterior of the body, serving as the birth canal and receptacle for sperm.
