The secretion of ovarian hormones is controlled by:

  • A. the anterior pituitary;
  • B. the hypothalamus;
  • C. FSH;
  • D. LH;
Correct Answer: B

Rationale: The correct answer is B: the hypothalamus. The hypothalamus secretes gonadotropin-releasing hormone (GnRH) which stimulates the anterior pituitary to release follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which in turn regulate the secretion of ovarian hormones (estrogen and progesterone). The anterior pituitary secretes FSH and LH in response to GnRH from the hypothalamus. Therefore, the hypothalamus plays a crucial role in controlling the secretion of ovarian hormones. Choices A, C, and D are incorrect because the anterior pituitary releases FSH and LH but is not the primary controller, FSH is a hormone released by the anterior pituitary but is not the primary controller, and LH is released by the anterior pituitary but is not the primary controller of ovarian hormone secretion.

Each spermatid and each ovum have ________. ________.

  • A. glans penis
  • B. 23 pairs of chromosomes
  • C. shaft of the penis
  • D. 23 chromosomes
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.

Inflammation of bone and bone marrow secondary to infection is called?

  • A. Osteitis.
  • B. Osteochondritis.
  • C. Osteom
  • D. Osteomyelitis
Correct Answer: D

Rationale: The correct answer is D: Osteomyelitis. Osteomyelitis refers to inflammation of bone and bone marrow secondary to infection. "Osteitis" (choice A) is a general term for bone inflammation without specifying infection. "Osteochondritis" (choice B) is inflammation of bone and cartilage, not bone marrow. "Osteom" (choice C) is not a recognized medical term. Therefore, based on the specific definition provided in the question, osteomyelitis is the most appropriate answer.

The epididymis:

  • A. is comm
  • B. shaped;
  • C. is crossed by the deferent duct (vas deferens);
  • D. displays tunica albuginea on the inside;
Correct Answer: C

Rationale: Step 1: The epididymis is a structure where sperm mature and are stored.
Step 2: The deferent duct (vas deferens) carries sperm from the epididymis to the urethra.
Step 3: Since the deferent duct crosses the epididymis, choice C is correct.
Summary: Choices A, B, and D are incorrect because they do not accurately describe the anatomical relationship between the epididymis and the deferent duct.

A client is learning how to maintain optimum bladder function. Which of the following strategies identifies the method of pressing on the bladder while seated on the toilet?

  • A. Valsalva maneuver
  • B. Kegel maneuver
  • C. Pelvic floor maneuver
  • D. Crede's maneuver
Correct Answer: D

Rationale: Crede's maneuver involves applying manual pressure to the bladder to aid in voiding.

The main function of progesterone in the menstrual cycle is to CHAPTER 4: REPRODUCTION COMPILED BY: ZAIDI YAACOB UNAUTORIED DUPLICATION IS PROBIHITED, FOR THE CIRCULATION OF BIO095 STUDENTS ONLY

  • A. stimulate development of corpus luteum .
  • B. stimulate development of the follicl
  • C. maintain endometrium lining.
  • D. trigger ovulation.
Correct Answer: C

Rationale: The correct answer is C because progesterone's main function in the menstrual cycle is to maintain the endometrium lining. Progesterone is produced by the corpus luteum after ovulation, and it helps prepare the endometrium for implantation of a fertilized egg. This hormone ensures that the endometrium is thick and ready to support a potential pregnancy.

Choice A is incorrect because progesterone is not responsible for stimulating the development of the corpus luteum; instead, it is produced by the corpus luteum itself.

Choice B is incorrect because progesterone does not stimulate the development of the follicle. The follicle is primarily influenced by estrogen during the follicular phase of the menstrual cycle.

Choice D is incorrect because ovulation is triggered by a surge in luteinizing hormone (LH), not progesterone. LH surge causes the release of the egg from the follicle.
