FRCR Anatomy Mock 2 — Questions and Answers
Question 1: Which structure passes through the foramen ovale of the skull base?
- Mandibular nerve (V3) (Correct answer)
- Maxillary nerve (V2)
- Middle meningeal artery
- Internal carotid artery
Correct answer: Mandibular nerve (V3)
The mandibular division of the trigeminal nerve (V3) passes through foramen ovale, along with the lesser petrosal nerve and accessory meningeal artery.
Question 2: On a coronal MRI of the knee, which structure lies within the intercondylar notch?
- Anterior and posterior cruciate ligaments (Correct answer)
- Medial and lateral collateral ligaments
- Popliteal artery and vein
- Infrapatellar fat pad
Correct answer: Anterior and posterior cruciate ligaments
The anterior and posterior cruciate ligaments are intra-articular but extrasynovial structures residing within the intercondylar notch of the femur.
Question 3: The right renal artery passes posterior to which structure on cross-sectional imaging?
- Inferior vena cava (Correct answer)
- Superior mesenteric artery
- Right renal vein
- Duodenum
Correct answer: Inferior vena cava
The right renal artery passes posterior to the inferior vena cava, right renal vein, and head of the pancreas to reach the right kidney.
Question 4: Which segment of the liver is located between the gallbladder fossa and the inferior vena cava on the visceral surface?
- Segment I (caudate lobe)
- Segment IV (quadrate lobe) (Correct answer)
- Segment V
- Segment VI
Correct answer: Segment IV (quadrate lobe)
Segment IV (quadrate lobe) lies between the gallbladder fossa laterally and the ligamentum teres/falciform ligament medially on the inferior surface of the liver.
Question 5: On a lateral chest radiograph, the posterior tracheal wall is bordered by which structure?
- Oesophagus (Correct answer)
- Aortic arch
- Right pulmonary artery
- Thymus
Correct answer: Oesophagus
The oesophagus lies directly posterior to the trachea; the tracheoesophageal stripe should be less than 4 mm on a lateral chest X-ray.
Question 6: In the carpal tunnel, which structure is most superficial (closest to the flexor retinaculum)?
- Palmaris longus tendon
- Median nerve (Correct answer)
- Flexor digitorum superficialis tendons
- Flexor pollicis longus tendon
Correct answer: Median nerve
The median nerve lies directly deep to the flexor retinaculum, making it the most superficial structure within the carpal tunnel proper.
Question 7: Which lymph node station receives primary lymphatic drainage from the lower lobe of the right lung?
- Subcarinal nodes (station 7) (Correct answer)
- Right paratracheal nodes (station 4R)
- Anterior mediastinal nodes (station 6)
- Aortopulmonary window nodes (station 5)
Correct answer: Subcarinal nodes (station 7)
Subcarinal nodes (station 7) receive primary drainage from both lower lobes and the right middle lobe before draining to the paratracheal chain.
