Fallopian Tube Anatomy Quiz

Study Notes

Fallopian Tube Anatomy

The fallopian tube is approximately 10 cm long.
Parts of the fallopian tube (from medial to lateral):
- Interstitium:
  - The intramural part of the tube embedded within the uterine wall.
  - The narrowest part of the tube.
  - Contains an anatomical sphincter made of circular muscle fibers.
- Isthmus:
  - The second narrowest part of the tube.
  - Contains a physiological sphincter that regulates movement of a fertilized egg from the ampulla to the isthmus.
- Ampulla:
  - The widest and longest part of the tube.
  - The site of fertilization.
  - Commonly affected by ectopic pregnancies.
  - Contains numerous mucosal folds known as plicae.
- Infundibulum:
  - Also known as the fimbrial part of the tube.
Adnexa: Refers to the ovary and fallopian tube together.
Peg Cells: These cells are present in the fallopian tube lining.
Genital Tuberculosis (TB):
- Most commonly affects the ampulla of the fallopian tube.
- Can lead to bilateral cornual block.
Gonococcal Infection:
- Can lead to fimbrial block (obstruction of the fallopian tube opening).
Tubal Patency Testing:
- Hysterosalpingography (HSG): Used to assess patency up to the isthmus.
- Laparoscopy: Can assess patency up to the isthmus.
- Hysteroscopy (using Essure): Assess patency up to the interstitium.
Tubal Ligation: A procedure to permanently prevent pregnancy, commonly performed on the fallopian tube.

Description

Test your knowledge on the anatomy of the fallopian tubes, including their parts and functions. This quiz covers critical aspects such as the interstitium, isthmus, ampulla, and infundibulum, as well as related cellular components. Ideal for students of human anatomy or reproductive biology.
