Question

Describe the structure of fallopian tube in a human female.

Answer 1

• Fallopian tube is located in the abdominal cavity of females, it is also known as oviduct or uterine tube.
• It is a long pair of narrow ducts which connects the ovary with the uterus.
  
• The tube on its inside is lined with a layer of mucous membrane that has many folds and papillae (small cone-shaped projections of tissue).
• Above this mucousal membrane are three layers of muscle tissue.

1. The innermost layer has spirally arranged fibres.
2. The middle layer has circular fibres.

3. The outermost layer has longitudinal fibres that end in many finger like branches called fimbriae near the ovaries which forms a funnel-shaped depository called the infundibulum.

• From this infundibulum extends a long central portion of the fallopian tube called the ampulla.
• A small region called isthmus connects the ampulla and infundibulum to the uterus.
• The last region of the fallopian tube called the intramural or uterine part which is located in the top portion or fundus of the uterus.
• This narrow tube continuous with the isthmus leads it through the thick uterine wall to the uterine cavity.
