Q9. A 7-year-old boy was brought to the hospital with multiple fractures of the humerus secondary to a fall from height. On examination, there is difficulty in flexion of the elbow and supination of the forearm and associated loss of sensation over the lateral aspect of the forearm. Which is the nerve most likely to be injured?

1. Median nerve
2. Radial nerve
3. Musculocutaneous nerve
4. Ulnar nerve

Ans. 3) Musculocutaneous nerve

• The musculocutaneous nerve innervates elbow flexion muscles like the biceps brachii and brachialis. It also aids in forearm supination via its branch, the lateral cutaneous nerve of the forearm, which supplies sensation to the forearm's lateral aspect.
• Consequently, difficulty in elbow flexion, supination, and loss of sensation in the forearm's lateral area suggest a musculocutaneous nerve injury, making it the most probable nerve involved.

Q16. ​The movements at the _____ joint permit a person to look to the right and left

1. Atlanto-occipital
2. Atlanto -axial
3. C2-C3
4. C3-C4

Ans. 2) Atlanto-axial joint

The atlanto-axial joint is formed between the atlas (C1 vertebra) and the axis (C2 vertebra) in the spine. This joint is responsible for rotational movements of the head. The axis (C2) has a peg-like structure called the dens or odontoid process, which fits into the atlas (C1), allowing for rotation. Therefore, the atlanto-axial joint permits the specific movements required for looking to the right and left.

Q17. Which of the following statements is false regarding the right coronary artery?

1. Its diameter is less than left coronary artery
2. It arises from the right aortic sinus
3. It gives rise to circumflex coronary branch
4. Right conal artery is it’s first branch

Ans. 3) It gives rise to the circumflex coronary branch.

This statement is false. The right coronary artery does not typically give rise to the circumflex coronary branch. The circumflex branch is a branch of the left coronary artery. It wraps around the left side of the heart and supplies blood to the left atrium and portions of the left ventricle.

Q18. What is the basis for the formation of omphaloceles?

1. Excessive length of the intestinal
2. Physiological hernia failing to go back
3. Herniation of liver
4. Herniation of umbilicus

Ans. 2) Physiological hernia failing to go back

Omphalocele is believed to result from a physiological herniation of abdominal organs into the base of the umbilical cord during early fetal development. Normally, the abdominal contents herniate into the umbilical cord at around 6 weeks of gestation but then return back into the abdominal cavity. However, in the case of omphalocele, this physiological herniation fails to go back, resulting in the persistence of the herniated organs outside the abdominal cavity.
