1. What forms the vaginal lining?

A. Squamous epithelium
B. Stratified epithelium
C. Vascular connective tissue
D. Muscle coat

Correct answer: A

Rationale: The vaginal lining is primarily formed by squamous epithelium. Squamous epithelium is the correct answer because it is the type of epithelium that lines the vaginal canal. Stratified epithelium consists of multiple layers and is not the primary type found in the vaginal lining. Vascular connective tissue and muscle coat are not the main components of the vaginal lining, making them incorrect choices.

D. The cervix dilates, and the products of conception are expelled.

Rationale: Incomplete abortion is defined as part of the products of conception, especially the fetus, being expelled while the placenta and membranes are retained. This is the correct definition, making option A the right choice. Option B is incorrect as it describes a complete abortion. Option C is incorrect because in incomplete abortion, the products of conception are not retained in the uterus, and the cervix may be open. Option D is incorrect as it describes a situation more likely to be seen in an inevitable abortion.

Choice A reflects the average amount of menstrual flow, choice B describes the components of menstrual flow, and choice C correctly identifies the ovarian hormones that influence the menstrual cycle.
