Which of the followings is the inferior portion of the uterus. It consists of two parts (supravaginal, vaginal), two openings (internal os, external os) and a cervical canal.

  • A. clitoris
  • B. Ovary
  • C. Cervix
  • D. implatation
Correct Answer: C

Rationale: The correct answer is C: Cervix. The cervix is the inferior portion of the uterus that consists of two parts (supravaginal, vaginal), two openings (internal os, external os), and a cervical canal. The clitoris (A) is a small sensitive organ located at the top of the vulva. The ovary (B) is a female reproductive organ that produces eggs and hormones. Implantation (D) refers to the attachment of a fertilized egg to the uterine lining, not a specific anatomical structure within the uterus. The cervix clearly fits the description provided, making it the correct answer.

Male sex chromosomes are represented as ________.

  • A. XX
  • B. XO
  • C. XY
  • D. XZ
Correct Answer: B

Rationale: The correct answer is C: XY. In humans, males have one X and one Y chromosome, while females have two X chromosomes. This combination determines an individual's sex. Choice A (XX) is incorrect because it represents the genotype for females. Choice B (XO) is incorrect as it denotes Turner syndrome in females with only one X chromosome. Choice D (XZ) is not a valid representation of male sex chromosomes in humans.

A thin single flat bone that forms the lower portion of the nasal septum is

  • A. Lacrimal bones
  • B. Nasal bones
  • C. Inferior nasal choncha
  • D. Vomer
Correct Answer: D

Rationale: The correct answer is D: Vomer. The vomer is a thin, single flat bone that forms the lower portion of the nasal septum. It articulates with the sphenoid, ethmoid, and maxillary bones. The lacrimal bones (A) are small bones forming part of the eye socket. Nasal bones (B) are two small bones that form the bridge of the nose. The inferior nasal concha (C) is a separate bone located in the nasal cavity, not part of the nasal septum. Therefore, the vomer is the correct answer as it specifically fits the description given in the question.

Which one of the following is not a component of semen?

  • A. Sperm
  • B. Seminal fluid
  • C. Prostatic fluid
  • D. Bulbourethral fluid
Correct Answer: D

Rationale: The correct answer is D: Bulbourethral fluid. Semen is composed of sperm, seminal fluid, and prostatic fluid. Bulbourethral fluid is not a component of semen but contributes to pre-ejaculatory fluid. This fluid is released from the Cowper's glands and serves to lubricate the urethra prior to ejaculation. The other choices (A, B, C) are all essential components of semen that play crucial roles in sperm transport, nourishment, and protection.

When are HCG levels the highest?

  • A. before pregnancy
  • B. first days of gestation
  • C. second month of pregnancy
  • D. end of pregnancy
Correct Answer: C

Rationale: The correct answer is C: second month of pregnancy. During the second month of pregnancy, HCG levels typically peak and reach their highest levels. This is because HCG is produced by the placenta, which develops and grows rapidly during this stage of pregnancy. Higher HCG levels during this time help support the developing fetus and maintain the pregnancy.

A: before pregnancy - HCG levels are not present before pregnancy.
B: first days of gestation - HCG levels are detectable shortly after implantation, but they continue to rise and peak in the second month.
D: end of pregnancy - HCG levels typically decrease towards the end of pregnancy as the placenta matures and other hormones take over to support the pregnancy.
