What type of tissue lines the testes?

Correct Answer: A

Rationale: The correct answer is A: Glandular tissue. The testes are lined with seminiferous tubules, which contain germ cells and Sertoli cells that are involved in sperm production. These cells are part of the glandular tissue that makes up the testes. Choices B, C, and D are incorrect because squamous, transitional, and stratified epithelium are not typically found lining the testes. Squamous epithelium is a type of epithelial tissue found in areas like the skin, transitional epithelium lines organs like the bladder, and stratified epithelium is present in structures like the skin and esophagus.

Correct Answer: A

Rationale: Complete abortion is characterized by a firm contracted uterus with a closed os. This closure of the os indicates that the products of conception have been completely expelled from the uterus. Choices B, C, and D are incorrect because a firm contracted uterus with a closed os is the hallmark sign of a complete abortion, not heavy bleeding, heavy cramping, or any other features.

Correct Answer: A

Rationale: The correct answer is A: Malaria. Malaria is a prevalent cause of abortion in Zambia due to its impact on maternal health. Malaria infection during pregnancy can lead to severe complications, including miscarriage. Choices B, C, and D are incorrect because while Tuberculosis, HIV, and Ascariasis are significant health issues, they are not the commonest cause of abortion in Zambia as Malaria.

Correct Answer: C

Rationale: Tubal abortion is most common when the ovum implants in the interstitial portion of the fallopian tube. This location is the narrowest part of the tube, making it more prone to obstruction or difficulty in the passage of the fertilized ovum. Choices A, B, and D are incorrect because tubal abortion is more likely to occur in the interstitial portion rather than the ampullary portion, isthmus, or infundibulum of the fallopian tube.

Correct Answer: B

Rationale: The correct answer is B: Cardinal ligament. The cardinal ligament is a primary uterine support structure that helps to anchor the uterus in place. The suspensory ligament also provides support for the uterus but is not considered a subsidiary uterine support. The transcervical ligament does not exist in anatomical terminology. The Maklouf ligament is a fictitious term and not recognized as a subsidiary uterine support structure.
