Reproductive System Flashcards

Reproductive Structures and Terminology

• Endometrium: Inner epithelial lining of the uterus, composed of columnar epithelial cells.
• Myometrium: Muscular layer of the uterus, responsible for contractions during childbirth.
• Perimetrium: Outer serous membrane covering the uterus; provides protection and support.
• Epimetrium: Not a recognized anatomical term; inaccurately describes an area above uterine linings.

Ovary and Ovum

• Ovary: Female organ that produces and releases ova (eggs); site of ovum maturation.
• Uterus: Provides a cavity for the fertilized ovum to develop during pregnancy.
• Fornix: A recess in the vagina that surrounds the cervix.
• Vestibule: Part of the external female genitalia.

Fallopian Tube

• Fallopian Tube: Duct that transports the ovum from the ovary to the uterus; also called uterine tube.
• Ductus Deferens: Duct for transporting sperm, distinctly different from the fallopian tube.

Uterine Anatomy

• Cervix: The inferior portion of the uterus that protrudes into the vagina; serves as a passageway between the uterus and vagina.
• Fundus: The uppermost part of the uterus, directing towards the abdominal cavity.
• Isthmus: The narrowest section of the uterus, located just above the cervix, playing a role in uterine structure.

Overall Significance

• Each structure plays a critical role in the reproductive process, from ovum production and transportation to nurturing fertilization and potential development of pregnancy. Understanding these terms aids in grasping female reproductive anatomy and physiology.
