The Reproductive System Quizlet Questions
Question 1 of 5
A mature ovarian follicle that is ready upper portion of the urethra just below to be ejected from an ovary is called a the junction with the urinary bladder. ________.
Correct Answer: D
Rationale: The correct answer is D: vesicular (Graafian) follicle. This structure is the final stage of maturation of an ovarian follicle before ovulation. It is characterized by a fluid-filled cavity and a bulging appearance on the surface of the ovary. It releases the mature egg during ovulation. Rationale: 1. Ejaculatory (choice A) relates to the male reproductive system, not the female reproductive system. 2. Primary oocyte (choice B) refers to an immature egg cell, not a mature follicle. 3. Seminal (choice C) is related to semen production in males, not the female ovary. In summary, the vesicular (Graafian) follicle (choice D) is the correct answer as it accurately describes the final stage of maturation of an ovarian follicle before ovulation.
Question 2 of 5
Parturition occurs the fetus is the ________. approximately how many days after a
Correct Answer: D
Rationale: The correct answer is D: chorionic villi. Parturition occurs when the fetus releases cortisol, which stimulates the production of prostaglandins leading to uterine contractions. Chorionic villi are the fetal tissue that produces cortisol, making it the key factor triggering labor. A: Amnion is the innermost membrane around the fetus, not directly involved in labor initiation. B: Placenta plays a role in nutrient exchange but not in triggering labor. C: 180 days is a set time frame and does not relate to the process of parturition.
Question 3 of 5
Which one of the following hormones is not a placental hormone.
Correct Answer: A
Rationale: The correct answer is A: oxytocin. Oxytocin is not a placental hormone because it is produced by the hypothalamus and stored in the posterior pituitary gland. Placental hormones are specifically produced by the placenta during pregnancy. Relaxin, estrogen, and human chorionic gonadotropin hormone are all placental hormones involved in various functions during pregnancy. Oxytocin, on the other hand, plays a role in uterine contractions during labor and milk ejection during breastfeeding, but it is not produced by the placenta.
Question 4 of 5
With respect to a male erection which of the following statements is incorrect.
Correct Answer: B
Rationale: The correct answer is B because it is incorrect to say that a male erection is triggered by motor inputs to the higher brain regions. Erections are primarily controlled by the autonomic nervous system, specifically the parasympathetic division. Parasympathetic activity leads to vasodilation of penile blood vessels, resulting in increased blood flow and erection. Choices A, C, and D are incorrect because during an erection, there is indeed an increase in parasympathetic activity, a decrease in sympathetic activity, and dilation of arterioles in the penis.
Question 5 of 5
Also called the birth canal, this is a muscular passageway from the cervix to the outside of the female's body:
Correct Answer: A
Rationale: The correct answer is A: Vagina. The vagina is the muscular passageway from the cervix to the outside of the female's body, serving as the birth canal. It is where sexual intercourse occurs and where menstrual flow exits the body. The uterus (B) is the organ where a fertilized egg implants and develops into a fetus, not the birth canal. Fallopian tubes (C) are where fertilization of an egg typically occurs, not part of the birth canal. Obstetrician (D) is a medical professional specializing in childbirth and pregnancy, not a part of the female reproductive anatomy.
