Question 1 of 5
A thin single flat bone that forms the lower portion of the nasal septum is
Correct Answer: D
Rationale: The correct answer is D: Vomer. The vomer is a thin, single flat bone that forms the lower portion of the nasal septum. It articulates with the sphenoid, ethmoid, and maxillary bones. The lacrimal bones (A) are small bones forming part of the eye socket. Nasal bones (B) are two small bones that form the bridge of the nose. The inferior nasal concha (C) is a separate bone located in the nasal cavity, not part of the nasal septum. Therefore, the vomer is the correct answer as it specifically fits the description given in the question.
Question 2 of 5
Out of the following, which is a flat bone?
Correct Answer: A
Rationale: The correct answer is A: Patella. The patella, also known as the kneecap, is a flat bone located in the front of the knee joint. It serves to protect the knee joint and improve the leverage of the quadriceps muscles during movement. The other choices, such as the shoulder blade (B), hand bone (C), and thigh bone (D), are not flat bones. The shoulder blade is a scapula, a flat and triangular bone. The hand bone refers to the metacarpal and phalanges, which are long bones. The thigh bone is the femur, a long bone in the upper leg. The patella's unique flat shape and location make it the correct choice.
Question 3 of 5
Which of the following portions of the placenta secretes HCG?
Correct Answer: A
Rationale: The correct answer is A: Syncytiotrophoblast. This layer of the placenta secretes human chorionic gonadotropin (HCG), a hormone crucial for maintaining pregnancy by supporting the corpus luteum to produce progesterone. Syncytiotrophoblast is a multinucleated layer formed from the fusion of cytotrophoblast cells and is responsible for hormone secretion. B: Cytotrophoblast is the inner layer of the trophoblast but does not secrete HCG. C: Endometrium is the lining of the uterus and is not part of the placenta. D: Chorion is a membrane that contributes to the formation of the placenta but does not secrete HCG.
Question 4 of 5
A 29 year old married computer programmer is c/o 'something strange' going on in his scrotum. Last month he felt a lump in his left testis, and it is still there. He has had some aching in the left testis but denies pain with urination or intercourse. Denies fever, malaise, night sweats. His PMH consisted of groin surgery as a baby and a tonsillectomy as an adolescent. He eats a healthy diet, exercises, denies tobacco or drugs. On exam the penis is circumcised with no lesions. No lymphadenopathy. Palpation of his scrotum is unremarkable on the right but indicates a large mass on the left. Placing a finger through the inguinal ring on the right, you have the patient bear down. Nothing is felt. You attempt to place your finger through the left inguinal ring but cannot get above the mass. On rectal exam, his prostate is unremarkable. What disorder of the tests is most likely the diagnosis?
Correct Answer: B
Rationale: The correct answer is B: Scrotal hernia. The patient's presentation with a lump in the left testis, aching, and a large mass on the left side of the scrotum, along with the inability to pass a finger above the mass through the left inguinal ring, suggests a scrotal hernia. This is further supported by the fact that bearing down does not reveal anything on the right side, ruling out hydrocele and varicocele. Scrotal edema would present with more generalized swelling in the scrotum rather than a localized mass. So, the key findings here point towards a scrotal hernia as the most likely diagnosis.
Question 5 of 5
The external genitalia of the female are collectively called the
Correct Answer: B
Rationale: The correct answer is B: vulva. The vulva includes all external female genital structures, such as the labia, clitoris, and mons pubis. The term "vulva" is the most inclusive and accurate choice, encompassing all components of the external female genitalia. The other options, A, C, and D, refer to specific parts of the vulva, making them incorrect in this context. The labia are the outer and inner folds surrounding the vaginal opening, the clitoris is a highly sensitive organ involved in sexual pleasure, and the mons pubis is the fatty tissue overlying the pubic bone.
