Question 1 of 5
The stage of labor that involves
Correct Answer: D
Rationale: The correct answer is D: dilation stage. This is the stage of labor where the cervix dilates to allow for the passage of the baby through the birth canal. This stage is crucial for the progression of labor and eventual delivery of the infant. Option A, relaxin, is a hormone that helps soften the cervix and pelvic ligaments but is not directly related to the stage of labor mentioned. Option B, progesterone, is a hormone involved in maintaining pregnancy and preparing the uterus for implantation, not specifically related to the dilation stage. Option C, chorion, is a membrane surrounding the fetus and plays a role in nutrient exchange, not directly related to the dilation stage of labor.
Question 2 of 5
Which of the following statements relating to the corpus luteum is incorrect.
Correct Answer: A
Rationale: The correct answer is A because the corpus luteum does not contain the zona pellucida. The zona pellucida is a glycoprotein layer surrounding the oocyte, not the corpus luteum. The other choices are incorrect because B is true - the corpus luteum degrades if fertilization does not occur; C is true - corpus luteum derives from Latin for yellow body; and D is true - the corpus luteum develops from the remaining follicle after ovulation.
Question 3 of 5
The shedding of the lining of the uterus along with some blood once a month. Also called a monthly period:
Correct Answer: C
Rationale: The correct answer is C: Menstruation. Menstruation is the process where the lining of the uterus sheds along with some blood once a month. This occurs in females who are not pregnant. Gestation (A) refers to the period of development of a baby in the womb. Conception (B) is the fertilization of an egg by sperm. Ovulation (D) is the release of an egg from the ovary. Menstruation best describes the shedding of the uterine lining and blood during a monthly period.
Question 4 of 5
Rita Chen, who is 25 years old and knows that she is not pregnant, is concerned because she has not had a menstrual period for three months. Her doctor described this condition as ______.
Correct Answer: B
Rationale: The correct answer is B: amenorrhea. Amenorrhea refers to the absence of menstrual periods, which is the condition Rita Chen is experiencing. Dysmenorrhea is painful periods, not absence of periods. Menometrorrhagia is excessive and prolonged menstrual bleeding. Polymenorrhoea is frequent menstrual periods, not absence of periods. In this case, Rita's lack of periods for three months aligns with the definition of amenorrhea.
Question 5 of 5
Structurally, the testicle is made up of:
Correct Answer: B
Rationale: The correct answer is B: lobules, delineated by connective septa. The testicle is structurally organized into lobules separated by connective tissue septa. Each lobule contains seminiferous tubules where sperm production occurs. This organization allows for efficient production and transport of sperm. Incorrect choices: A: Intratesticular spermatic ducts - Incorrect, as the testicle contains seminiferous tubules, not spermatic ducts. C: The cortical zone, in the center - Incorrect, as the testicle structure does not have a defined cortical zone. D: The medullar zone, at the periphery - Incorrect, as the medullary zone is not at the periphery but rather towards the center of the testicle.
