Anatomy Reproductive System Quizlet Questions
Question 1 of 5
A fertilized egg, which represents the first cell of a new individual, is called a(n) ________.
Correct Answer: B
Rationale: The correct answer is B: zygote. A zygote is formed when a sperm cell fertilizes an egg cell, marking the beginning of a new individual's development. It is the first cell of the new organism with a full set of chromosomes. A: Blastocyst is a later stage of development after the zygote has undergone several cell divisions. C: Fetus refers to the later stages of development when the embryo has developed recognizable features. D: Embryo is the stage after the zygote when the cells start to differentiate into different tissues and organs.
Question 2 of 5
Which hormone is primarily produced by the corpus luteum?
Correct Answer: C
Rationale: The correct answer is C: Progesterone. The corpus luteum is a temporary endocrine structure in the ovaries that forms after ovulation. Its main function is to produce progesterone, which helps prepare the uterine lining for implantation of a fertilized egg. Follicle stimulating hormone (FSH) is produced by the pituitary gland to stimulate follicle development, not by the corpus luteum. Testosterone is mainly produced by the testes in males and a small amount by the ovaries in females, not by the corpus luteum. Progesterone is the key hormone produced by the corpus luteum, making choice C the correct answer.
Question 3 of 5
The ducts or tubes responsible for the ________. receiving the ovulated oocyte and
Correct Answer: D
Rationale: The correct answer is D: uterine (fallopian) tubes. These tubes are responsible for receiving the ovulated oocyte (egg) and providing the site for fertilization. The fallopian tubes are specifically designed to transport the egg from the ovary to the uterus for potential fertilization by sperm. Choice A, glans penis, is incorrect as it is part of the male reproductive system and not involved in receiving the ovulated egg. Choice B, shaft, is also incorrect as it refers to the main part of the penis and is not related to female reproductive functions. Choice C, scrotum, is incorrect as it is part of the male reproductive system and has no role in receiving the ovulated egg.
Question 4 of 5
Each spermatid and each ovum have ________. ________.
Correct Answer: D
Rationale: The correct answer is D: 23 chromosomes. Spermatids and ova are haploid cells formed through meiosis, containing only half the number of chromosomes (23) as a normal diploid cell. This is essential for maintaining the proper chromosome number when fertilization occurs. Glans penis and shaft of the penis (choices A and C) are structures related to the male reproductive system but are not present in spermatids or ova. Having 23 pairs of chromosomes (choice B) would result in a total of 46 chromosomes, which is incorrect for these gametes.
Question 5 of 5
The presence of more oxytocin oxygen to, and remove waste from, receptors in the uterus leads to weak, irregular contractions known as the embryonic blood by the ________ ________. week of pregnancy.
Correct Answer: C
Rationale: The correct answer is C: Braxton Hicks contractions. These contractions are weak, irregular contractions that occur in the uterus during pregnancy. They are often referred to as "practice contractions" as the body prepares for labor. The presence of more oxygen and removal of waste from the uterus can trigger Braxton Hicks contractions. Choice A, dystocia, refers to difficult or prolonged labor, not weak contractions. Choice B, first week, is not relevant to the question as Braxton Hicks contractions typically occur later in pregnancy. Choice D, second week, is also not correct as Braxton Hicks contractions occur later in pregnancy, typically in the third trimester.
