1. During fertilization, the portion of the decidua covering the blastocyst is called:

• A. Decidua basalis
• B. Decidua Vera
• C. Decidua parietalis
• D. Decidua capsularis

Correct answer: D

Rationale: During fertilization, the decidua capsularis is the specific portion of the decidua that covers the blastocyst, providing protection and support. Decidua basalis refers to the part of the decidua located at the site of implantation on the maternal side. Decidua vera is the remainder of the decidua lining the uterus. Decidua parietalis is the portion of the decidua that lines the rest of the uterine cavity, except for the site of implantation. Therefore, in the context of fertilization, the decidua capsularis is the correct answer.

2. How does human sperm move?

• A. Flagella
• B. Cilia
• C. Neutrophils
• D. None of the above

Correct answer: A

Rationale: Human sperm moves using flagella, which are whip-like structures that aid in propulsion. Flagella are tail-like structures found in sperm cells and help them swim towards the egg for fertilization. Cilia are shorter, hair-like structures that are not involved in the movement of sperm. Neutrophils are a type of white blood cell involved in the immune response and are not related to sperm locomotion.

3. What is a cord inserted to the very edge of the placenta known as?

• A. Battledore insertion
• B. Placenta velamentosa
• C. Placenta accreta
• D. Vasa Praevia

Correct answer: A

Rationale: A cord inserted to the very edge of the placenta is known as battledore insertion. This occurs when the cord is attached to the fetal membranes at the placental margin rather than directly to the placental tissue. Placenta velamentosa refers to the condition where the umbilical cord inserts into the fetal membranes before it reaches the placenta. Placenta accreta is a condition where the placenta attaches too deeply into the uterine wall. Vasa Praevia is a condition where fetal blood vessels run across or near the internal cervical opening.

4. Basal body temperature rise of _____ is seen in the luteal phase due to the thermogenic effects of a metabolite of progesterone in a normal cycle:

• A. 0.1-0.5
• B. 0.2-0.5
• C. 1.0-2.0
• D. 1.5-2.0

Correct answer: B

Rationale: A basal body temperature rise of 0.2-0.5 degrees Celsius is typically seen in the luteal phase of the menstrual cycle due to the thermogenic effects of a metabolite of progesterone. This temperature rise helps to indicate ovulation has occurred. Choices A, C, and D are incorrect as they do not reflect the usual range of temperature increase observed during the luteal phase. A rise of 0.1-0.5 degrees Celsius is too narrow (eliminating choice A), while ranges of 1.0-2.0 and 1.5-2.0 degrees Celsius are too high and not consistent with the expected basal body temperature changes during the menstrual cycle.

5. What type of tissue lines the testes?

• A. Glandular tissue.
• B. Squamous epithelium.
• C. Transitional epithelium.
• D. Stratified epithelium.

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.
