The medical term expressing surgical fixation of the breast(s) is __________

Correct Answer: A

Rationale: The correct answer is A: mammoplasty. "Mammo-" refers to the breast, and "-plasty" indicates surgical repair or reconstruction. This term specifically denotes surgical fixation of the breast(s). B: Mastopexy refers to a breast lift, not fixation. C: Hysteropexy involves fixing the uterus, not the breast. D: Vaginoplasty refers to surgical reconstruction of the vagina, not the breast.

Correct Answer: C

Rationale: Step-by-step rationale for why choice C (corpora cavernosa) is correct: 1. Corpora cavernosa are erectile tissue in the penis, not internal male genital organs. 2. Testicles, deferent ducts, and bulbourethral glands are actual internal male genital organs. 3. Corpora cavernosa are involved in penile erection, not in male reproductive system functions. Summary of why other choices are incorrect: A: Testicles - Produces sperm and male sex hormones. B: Deferent ducts - Transport sperm from the testicles to the urethra. D: Bulbourethral glands - Produce pre-ejaculatory fluid to lubricate the urethra.

Correct Answer: B

Rationale: The correct answer is B: pelvic cavity. The ovary is located in the pelvic cavity because it is part of the female reproductive system and is situated within the pelvis. It is specifically housed in the adnexal region of the pelvis, attached to the uterus via ligaments. The abdominal cavity (choice A) is too high up in the body to house the ovary. The inguinal region (choice C) is located in the lower abdomen near the groin and does not contain the ovary. The lumbar region (choice D) is located in the lower back and is not where the ovary is located.

Correct Answer: B

Rationale: The correct answer is B: the ovarian branch of the uterine artery. The ovary receives its blood supply primarily from the ovarian artery, which arises from the abdominal aorta. However, the ovarian artery is a short vessel that anastomoses with the uterine artery, providing the main vascularization of the ovary. The other choices are incorrect because: A) the gonadal artery arises from the internal iliac artery, not the abdominal aorta; C) the ovarian artery does not arise from the external iliac artery; D) there is no specific Fallopian artery responsible for ovarian vascularization.

Correct Answer: D

Rationale: The correct answer is D: cervix. The vagina is inserted on the cervix, which is the lower part of the uterus that connects the uterus to the vagina. The cervix serves as a passageway for sperm to enter the uterus and for menstrual blood to exit. The other choices (A: uterine corpus, B: uterine cervix, C: Fallopian tube) are incorrect because they do not accurately describe the anatomical structure where the vagina is inserted. It is essential to understand the specific anatomical relationships to identify the correct answer.
