The normal site of fertilization is:

Correct Answer: D

Rationale: The correct answer is D: the oviduct. Fertilization occurs in the oviduct, specifically in the ampulla region. Sperm meets the egg in the oviduct where fertilization takes place. The other choices, A: the uterus, B: the vagina, and C: the ureter, are incorrect because fertilization does not occur in these locations. The uterus is where the fertilized egg implants and develops into a fetus. The vagina is the passage for sperm to enter the reproductive system. The ureter is a tube that connects the kidney to the bladder, and is not involved in fertilization.

Correct Answer: A

Rationale: Rationale: The correct answer is A: clitoris. The clitoris is an erectile organ responsible for sexual sensations due to its high concentration of nerve endings. It becomes engorged with blood during arousal, enhancing sensitivity. Ovary (B), Cervix (C), and Breast (D) are not erectile organs and do not directly contribute to sexual sensations. Ovary produces eggs, Cervix is part of the reproductive system, and Breast is a secondary sexual characteristic involved in breastfeeding.

Correct Answer: C

Rationale: The correct answer is C: cervicorrhaphy. "Cervico-" refers to the neck of the uterus, and "-rrhaphy" means suture. Therefore, cervicorrhaphy is the correct term for the procedure of suturing the neck of the uterus. A: Cervicography is a diagnostic imaging technique, not a procedure for suturing. B: Perineorrhaphy involves suturing the perineum, not the neck of the uterus. D: Cervicorrhexis refers to cutting or incising the neck of the uterus, not suturing it.

Correct Answer: C

Rationale: The correct answer is C because the straight tubules open into the rete testis, which is a network of tubules located at the hilum of the testis. This is where sperm produced in the seminiferous tubules are collected and transported to the epididymis for maturation. The other choices are incorrect because A is not accurate as straight tubules are not located inside the lobules, B is incorrect as straight tubules are a separate structure from the convoluted seminiferous tubules, and D is inaccurate as straight tubules do not open directly into the epididymal duct.

Correct Answer: A

Rationale: Step-by-step rationale: 1. The corpus spongiosum surrounds the urethra in the male external genital organ, aiding in the passage of urine and semen. 2. This structure is crucial for maintaining proper urinary and reproductive functions. 3. The other choices are incorrect because: - Choice B is vague and does not specifically relate to the male genital organ. - Choice C refers to the corpora cavernosa, which are erectile tissue in the penis, not the urethra. - Choice D describes the root of the penis but does not specifically relate to the corpus spongiosum.
