The Reproductive System Quizlet Questions
Question 1 of 5
Which one of the following is not one of the secondary sex characteristics typical of males?
Correct Answer: D
Rationale: The correct answer is D: Development of breast tissue. This is not a secondary sex characteristic typical of males because breast development is a primary sex characteristic associated with females due to the presence of estrogen. In males, the secondary sex characteristics include deepening voice, increased growth of body hair, and enlargement of skeletal muscle mass due to the effects of testosterone. Breast tissue development in males, known as gynecomastia, is abnormal and can be caused by hormonal imbalances or certain medical conditions.
Question 2 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 3 of 5
The spongy tissue of the penis fills
Correct Answer: D
Rationale: The spongy tissue of the penis fills with blood during an erection to cause the penis to become rigid. This process is essential for maintaining an erection during sexual activity. Spermatogenesis refers to the production of sperm, not the filling of spongy tissue. Circumcision does not involve the filling of spongy tissue with blood. Ejaculation is the release of semen and does not involve the filling of spongy tissue. Therefore, the correct answer is D as it accurately describes the physiological process of penile erection.
Question 4 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 5 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.
