    Correct

    • If a 55-year old gentleman who has suffered a stroke, develops a tremor in his fingers that worsens on reaching for an object, what part of his brain is likely to be involved?

      Your Answer: Cerebellum

      Explanation:

      The cerebellum plays an important role in the integration of sensory perception and motor output. Multiple neural pathways link the cerebellum with the motor cortex and the spinocerebellar tract. The cerebellum uses the constant feedback on body position to fine-tune the movements and integrates these pathways. The patient described here has a characteristic cerebellar tremor that is a slow, broad tremor of the extremities and occurs at the end of a purposeful movement.

    Correct

    • Where does the ejaculatory duct open into?

      Your Answer: Prostatic urethra

      Explanation:

      There are two ejaculatory ducts, one on either side of the midline. Each ejaculatory duct is formed by the union of the duct from the seminal vesicles with the ductus deferens. They start at the base of the prostate and run forward and downward between the middle and lateral lobes and along the side of the prostatic utricle to end in the prostatic urethra.

    Correct

    • With respect to far accommodation, which of the following is a TRUE statement?

      Your Answer: The ciliary muscles are relaxed

      Explanation:

      Myopia or near-sightedness is a disease due to elongated eyeballs or too strong a lens. For far accommodation (focus of a distant object onto the retina), the lens needs to decrease its refractive power, or in other words, increase its focal length. This is done by relaxation of ciliary muscles which tightens the zonular fibres and flattening of the lens. Relaxation of the zonular fibres, rounding of the lens, shortening of the focal length and constriction of the pupil occurs during near accommodation.

    Incorrect

    • A 40 year old patient with an history of obesity has been diagnosed with meralgia parasthetica. The condition was discovered to be caused by the pinching of the lateral femoral cutaneous nerve. Injuries at what spinal levels usually affect this nerve?

      Your Answer: L1, L2

      Correct Answer: L2, L3

      Explanation:

      The lateral femoral cutaneous nerve of the thigh arises from the dorsal division of the lumbar plexus of the second and the third lumbar nerves (L2 – L3). Spinal injuries at this level are likely to affect the lateral femoral cutaneous nerve. The lateral femoral cutaneous nerve innervates the skin on the lateral aspect of the thigh.

      Your Answer: The mandibular nerve, a branch of the trigeminal nerve innervates some of the facial muscles

      Correct Answer: They are in the same subcutaneous plane as the platysma muscle

      Explanation:

      The facial muscles generally originate from the facial bones and attach to the skin, in the same plane as the platysma muscle. They are all innervated by cranial nerve VII (the facial nerve). The occipitofrontalis muscle consists of two parts: The occipital belly, near the occipital bone, and the frontal belly, near the frontal bone.

    Correct

    • A patient gives a history of dull discomfort in her abdomen associated with pain that she points to be on her right shoulder and right scapula. The following organs are most likely to be source of her pain:

      Your Answer: Liver, duodenum and gallbladder

      Explanation:

      Referred pain is felt at a point away from the source of the pain or the unpleasant sensation. It arises when a nerve is damaged or compressed at a point but the pain is felt at another site that is the territory of that nerve. Common abdominal causes of referred pain to the shoulder and the shoulder blade are the liver, duodenum and gall bladder.

    • The fundus of the stomach receives blood supply from the same artery as the greater curvature of the stomach. Which of the following arteries when ligated will disrupt blood supply to the fundus of the stomach through this artery?

      Your Answer: Splenic

      Explanation:

      The fundus of the stomach along with the greater curvature of the stomach receive blood supply from the short gastric artery. The short gastric artery arises from the end of the splenic artery. The ligation of the splenic artery therefore would cause a disruption of blood supply to the fundus of the stomach.

    Correct

    • The muscle which has an antagonistic action to the serratus anterior muscle and is one of the retractors of the scapula is the?

      Your Answer: Rhomboid major

      Explanation:

      Protraction is accomplished by the actions of the serratus anterior, pectoralis major, and pectoralis minor muscles. Retraction is accomplished by the actions of the trapezius, rhomboids, and latissimus dorsi muscles.

      The rhomboid major arises from the second, third, fourth and fifth thoracic vertebrae. It is inserted into a narrow tendinous arch attached to the root of the spine of the scapula and the inferior angle. By its insertion in the inferior angle of the scapula, it acts on this angle and produces a slight rotation of the scapula on the side of the chest. It also retracts the scapula by working with the trapezius muscle.

    • A patient who has used NSAIDS for many years presents to the A&E with symptoms of acute haemorrhagic shock. An emergency endoscopy is done that shows that a duodenal ulcer has perforated the posterior wall of the first part of the duodenum. Which artery is most likely to be the cause of the haemorrhage?

      Your Answer: Gastroduodenal

      Explanation:

      The gastroduodenal artery is a branch of the hepatic artery and descends near the pylorus between the first part of the duodenum and the neck of the pancreas to divide at the lower border of the duodenum into the right gastroepiploic and pancreaticoduodenal arteries. Before it divides, it gives off a few branches to the pyloric end of the stomach and to the pancreas. The artery that is most likely involved in this situation is the gastroduodenal artery since it is posterior to the first part of the duodenum.

      Your Answer:

      Correct Answer: Pancreas

      Explanation:

      The presence or absence of the mesentery determines mobility of abdominal contents. Structures like the stomach, transverse colon and appendix have mesenteries and thus are relatively mobile. In contrast, the pancreas is a retroperitoneal (behind the peritoneum) structure and therefore is fixed. The greater omentum is a large mobile fold of omentum that hangs down from the stomach .

      Your Answer:

      Correct Answer: Azygos vein

      Explanation:

      The azygos vein is formed by the union of the right subcostal veins and the ascending lumbar veins at the level of the 12th thoracic vertebra. It enters the thorax through the aortic hiatus to ascend in the posterior mediastinum and arching over the right main bronchus posteriorly at the root of the right lung to join the superior vena cava before it pierces the pericardium.

      The basilic vein is a vein on the medial aspect of the arm that ascends to become the axillary vein.

      The cephalic vein is also a vein of the arm.

      The external jugular and brachiocephalic vein are not in the posterior mediastinum.

      The median cubital vein is found in the cubital fossa of the arm.

      Your Answer:

      Correct Answer: Meningitis

      Explanation:

      Diagnosis of meningitis can be carried out with examination of cerebrospinal fluid (CSF) with a lumbar puncture (LP). In a case of bacterial meningitis, the CSF analysis will show:

      – Opening pressure: > 180 mmH2O

      – White blood cell count: 10–10 000/μl with neutrophil predominance

      – Glucose: < 40 mg/dl – CSF glucose to serum glucose ratio: < 0.4 – Protein: > 4.5 mg/dl

    Incorrect

    • A 30-year old lady was admitted to the general surgical ward after a diagnosis of perforation of the first part of the duodenum that resulted from a long standing ulcer. If this perforation led to the expulsion of the gastric content that resulted to the erosion of an artery found in this part of the duodenum (the posterior of the first part of the duodenum). Which of the following arteries is this most likely to be?

      Your Answer:

      Correct Answer: Gastroduodenal

      Explanation:

      The proximal part of the duodenum is supplied by the gastroduodenal artery. This artery is found descending behind the first part of the duodenum after branching from the hepatic artery. If gastric content was to be expelled in the posterior portion of the first part of the duodenum, then this artery would be most likely to be damaged. The common hepatic artery and the left gastric artery are branches of the coeliac trunk that are found superior to the duodenum. The proper hepatic artery is a branch of the common hepatic artery also found superior to the duodenum. The superior mesenteric artery is found behind the pancreas as a branch of the aorta that is at the bottom of the L1 level. The right gastric artery arises above the pylorus from the proper hepatic artery and supplies the lesser curvature of the stomach. The intestinal arteries supply the ileum and the jejunum.

    Incorrect

    • A patient who following 20 years of working in the asbestos industry develops malignant mesothelioma and is scheduled for pleuropneumonectomy to remove the entire pleura and lung on the affected side. Which layer would provide a natural cleavage plane for surgical separation of the costal pleura from the thoracic wall?

      Your Answer:

      Correct Answer: Endothoracic fascia

      Explanation:

      The endothoracic fascia is connective tissue that is between the costal parietal pleura and the inner aspect of the chest wall. Removing this layer of connective tissue would make it easy to separate the costal pleura from the thoracic wall.

      Deep fascia: is not found around the lungs. It is a layer of connective tissue that invests a muscle or a group of muscles.

      Parietal pleura: part of the pleura that lines the inner surface of the chest/thoracic cavity.

      Visceral pleura: is the serous membrane that lines the surface of the lungs.

      Transversus thoracis muscle fascia is associated only with the muscle transversus thoracis.

      Peritracheal fascia: a layer of connective tissue that invests the trachea. It is not associated with the thoracic wall or the costal pleura.
