heart and lungs?
A. Greater splanchnic nerve

C
apical lung tumour=pancoast tumour
affects SVC, sympathetic chain, c8/t1 brachial plexus, recurrent laryngeal nerve

After a prolonged bout of flu, a teacher develops a sharp stabbing pain in her chest and shoulders
when she breathes deeply. The patient’s GP diagnoses her with pleuritis. The pain in her
shoulders is MOST LIKELY due to inflammation of parietal pleura related closely to the…

During video-assisted thoracoscopic surgery to remove an upper lobe of the right lung affected by
bronchiectasis, the lung root was examined carefully by the attending surgeon. The root of the
right lung…

Which of the following structures is MOST LIKELY to be compressed in this patient?
A. Ascending aorta
B. Right recurrent laryngeal nerve
C. Thoracic duct

C
trachea bifurcation is in posterior mediastinal but trachea is in superior
A patient is undergoing surgery for rectal cancer. During this surgery, the surgeon needs to

this patient, in addition to the visceral afferents?

A new-born baby is brought to the clinic because of repeated vomiting. Imaging reveals volvulus
due to Meckel’s diverticulum. The midgut is at risk for volvulus because it is…
A. intraperitoneal
B. retroperitoneal
C. secondarily retroperitoneal
D. A and C are both true
A
midgut is both secondarily and intra but then volvulus is to do with the vitelline duct not obliterating and instead, portion of the intestine twists upon itself bringing the mesentery with it –> intra
