A solid ball of 12-16 cells having undergone mitotic division after fertilization is:
- A. Zygote
- B. Blastomere
- C. Morula
- D. Blastocyst
Correct Answer: C
Rationale: A morula is a stage in embryonic development where a solid ball of 12-16 cells is formed after several rounds of mitotic division following fertilization. The zygote is the initial cell formed by the fusion of sperm and egg. Blastomere refers to individual cells in a developing embryo. A blastocyst is a later stage where a fluid-filled cavity forms within the embryo. Therefore, the correct answer is 'Morula.'

Which part of the female reproductive system remains blocked after tubectomy?
- A. Fallopian tube
- B. Cervix
- C. Uterine cavity
- D. None
Correct Answer: A
Rationale: After a tubectomy procedure, the Fallopian tube remains blocked. This is the correct answer because tubectomy involves the surgical blocking or sealing of the Fallopian tubes to prevent eggs from reaching the uterus, thus preventing pregnancy. Choice B, the cervix, is incorrect as it is not blocked during a tubectomy. Choice C, the uterine cavity, is also incorrect as the procedure does not involve blocking this part of the reproductive system. Choice D, none, is incorrect as the purpose of tubectomy is to block the Fallopian tubes.
Which of the following are layers of the anterior abdominal wall?
- A. Linear albicantes
- B. Superficial fascia
- C. Visceral peritoneum
- D. Fascia transversalis

Choices C and D, Visceral peritoneum and Fascia transversalis, respectively, are not layers of the anterior abdominal wall. The visceral peritoneum is a membrane covering the abdominal organs, and the fascia transversalis is a layer deep to the transversus abdominis muscle.

Therefore, 'Amenorrhoea' is the most appropriate term for the described menstrual disorder.
