Question

Each fallopian tube is about _____ long and extends _______.

Answer 1

Fallopian tubes:

In the female pelvis, the uterus and ovaries are connected by bilateral fallopian tubes, they serve as conduits for the movement of oocytes and fertilization.

1. A fallopian tube's length and diameter are respectively 10–13 cm (4–5 inches) and 0.5–1.2 cm (0.2–0.6 inches).
2. A mucous membrane layer with numerous folds and papillae—tiny tissue projections in the shape of cones—lines the tube's canal.
3. Muscle tissue covers the mucous membrane in three layers, with the innermost layer having spirally arranged fibers, the middle layer having circular fibers, and the outermost sheath having longitudinal fibers that culminate in many finger-like branches (fimbriae) close to the ovaries.
4. The main function of the fallopian tube is to collect the mature ovum from ovaries and provide passage to the fertilized ovum to reach the uterus for implantation.
5. The fertilisation of the ovum with sperm takes place in the ampulla region of the fallopian tube.

Final answer: Each fallopian tube is about 10-12 cm long and extends from the periphery of each ovary to the uterus.
