Which of the following are not parts of the clitoris?
- A. corpora cavernosa
- B. crura
- C. glans
- D. corpus spongiosum
Correct Answer: D
Rationale: The correct answer is D: corpus spongiosum. The clitoris does not have a corpus spongiosum. The clitoris is made up of the corpora cavernosa, crura, and glans. The corpus spongiosum is a part of the male anatomy, specifically found in the penis, and is responsible for maintaining erection by filling with blood during arousal. Therefore, the corpus spongiosum is not a part of the clitoris and is the correct answer.

The lateral extremity of the Fallopian tube:
- A. opens in the abdominal cavity;
- B. captures the ovule released by the ovary;
- C. displays flared edges;
- D. is linked to the uterus through the uterine ostium;
Correct Answer: D
Rationale: Step-by-step rationale for why choice D is correct:
1. The lateral extremity of the Fallopian tube is connected to the uterus through the uterine ostium.
2. This connection allows the passage of the ovum from the Fallopian tube to the uterus for implantation.
3. The uterine ostium serves as the entry point for the ovum to travel from the Fallopian tube to the uterus.
4. Therefore, choice D is correct as it accurately describes the anatomical connection between the Fallopian tube and the uterus.
Summary:
- Choice A is incorrect because the lateral extremity of the Fallopian tube does not open in the abdominal cavity.
- Choice B is incorrect because the Fallopian tube does not capture the ovule released by the ovary.
- Choice C is incorrect because the lateral extremity of the Fallopian tube does not display flared edges.
- Choice D is correct as it accurately describes the anatomical connection
Inhibin is
- A. is secreted by Sertoli cells to inhibit follicle stimulation hormone from the anterior pituitary.
- B. is secreted by the anterior pituitary to inhibit testosterone secretion.
- C. is secreted by Sertoli cells to inhibit testosterone secretion
- D. is secreted Leydig cells to inhibit Sertoli cells
Correct Answer: A
Rationale: Inhibin is secreted by Sertoli cells to inhibit follicle stimulating hormone (FSH) from the anterior pituitary. This is the correct answer because inhibin acts as a negative feedback mechanism to regulate FSH levels in the body. Sertoli cells are specifically involved in spermatogenesis and play a crucial role in regulating FSH secretion through inhibin. Choices B, C, and D are incorrect because inhibin does not inhibit testosterone secretion or act on Leydig cells. It specifically targets FSH secretion to regulate the process of spermatogenesis.
The primary germ layer that gives rise
- A. areolar glands to the mucosae and associated glands
- B. lacrimal glands is the ________.
- C. sweat glands
- D. ectoderm
Correct Answer: D
Rationale: The correct answer is D: ectoderm. The primary germ layer that gives rise to structures like the lacrimal glands is the ectoderm, which is one of the three primary germ layers during embryonic development. The ectoderm gives rise to tissues such as the epidermis of the skin, nervous system, and various glands including lacrimal glands. Choice A, areolar glands to the mucosae and associated glands, is incorrect as they are derived from the mesoderm. Choice C, sweat glands, is also incorrect as they are derived from the ectoderm but are not the primary germ layer responsible for lacrimal glands. Choice B, lacrimal glands is the _______, is incorrect as it does not provide a complete statement and is not a primary germ layer.
A client has been advised to use a pessary to provide support to the uterus. The nurse educates the client about pessary management and the precautions related to its use. In which of the following situations should the client report to the physician?
- A. Regarding a Pap test of the client
- B. Regarding the maintenance of a pessary
- C. When a white or yellow discharge from the vagina develops
- D. Regarding a culture and sensitivity test of vagina
Correct Answer: C
Rationale: Abnormal discharge can indicate infection or other complications requiring medical attention.
The sperm cells:
- A. become mobile in the seminal fluid;
- B. are microscopic cells;
- C. are stored in the crotum;
- D. are of three different kinds;
Correct Answer: A
Rationale: Step-by-step rationale for choice A being correct:
1. Sperm cells need to be mobile to reach the egg for fertilization.
2. Seminal fluid provides the environment for sperm motility.
3. Sperm cells acquire motility in the seminal fluid due to specific nutrients and ions present.
Summary of why other choices are incorrect:
- Choice B: Being microscopic is a general characteristic of sperm cells but not specific to their mobility.
- Choice C: Sperm cells are stored in the epididymis, not the "crotum."
- Choice D: Sperm cells are all of the same kind, not three different kinds.
