Commonest location of diaphragmatic (bochdalek)hernia in children is
- A.
Retrosternal
- B.
.posterior and left
- C.
.posterior and right
- D.
.central
Correct Answer
A. RetrosternalExplanation
The correct answer is retrosternal. A diaphragmatic hernia, specifically a Bochdalek hernia, is a congenital condition where there is a hole or weakness in the diaphragm muscle allowing abdominal organs to protrude into the chest cavity. The retrosternal location refers to the area behind the sternum or breastbone. This is the most common location for diaphragmatic hernias in children.Rate this question:

Which of the following does not drain into coronary sinus
- A.
. Anterior cardiac vein
- B.
Small cardiac vein
- C.
Middle cardiac vein
- D.
.great cardiac vein
Correct Answer
A. . Anterior cardiac veinExplanation
The anterior cardiac vein drains directly into the right atrium of the heart, rather than into the coronary sinus. The coronary sinus is a large vein located on the posterior surface of the heart that collects blood from other cardiac veins and then empties it into the right atrium. Therefore, the anterior cardiac vein is the correct answer as it does not drain into the coronary sinus.Rate this question:

True about thoracic part of sympathetic trunk
- A.
First five ganglia give preganglionic fibres
- B.
The sympathetic trunk has 13 segmentally arranged ganglia
- C.
It is the most medially placed structure in the mediastinum
- D.
The first ganglion is often fused with the inferior cervical ganglion to form stellate ganglion
Correct Answer
A. First five ganglia give preganglionic fibresExplanation
The statement that the first five ganglia give preganglionic fibers is true. The sympathetic trunk is a paired chain of ganglia that runs parallel to the spinal cord. It consists of a series of ganglia that give off preganglionic fibers, which then synapse with postganglionic fibers. The first five ganglia in the thoracic part of the sympathetic trunk give rise to preganglionic fibers that innervate various organs and structures in the thoracic region. Therefore, this statement accurately describes the thoracic part of the sympathetic trunk.Rate this question:

Base of heart is mainly formed by
- A.
.right atrium
- B.
Left atrium
- C.
Right ventricle
- D.
Left ventricle
Correct Answer
A. .right atriumExplanation
The base of the heart is mainly formed by the right atrium. The base of the heart is the top portion of the heart where the major blood vessels enter and exit. The right atrium is located at the top right side of the heart and receives deoxygenated blood from the body. It then pumps this blood into the right ventricle, which is located below the right atrium. Therefore, the right atrium plays a significant role in forming the base of the heart.Rate this question:

.Shape of tracheal crtilage
- A.
W shaped
- B.
O shaped
- C.
.C shaped
- D.
D shaped
Correct Answer
A. W shapedExplanation
The shape of tracheal cartilage is W shaped. This is because the trachea needs to be flexible enough to allow for movement during breathing, but also sturdy enough to maintain its shape and prevent collapse. The W shape provides a balance between flexibility and stability, allowing the trachea to expand and contract as needed while still providing support.Rate this question:

.In midclavicular plane,lower border of lung lies at the level of
- A.
.4th rib
- B.
.6th rib
- C.
.8th rib
- D.
.10th rib
Correct Answer
A. .4th ribExplanation
The lower border of the lung lies at the level of the 4th rib in the midclavicular plane. This means that when looking at the chest from the front, the bottom edge of the lung can be seen at the level of the 4th rib.Rate this question:

.Length of esophagus in adults
- A.
.25cm
- B.
.10cm
- C.
15cm
- D.
20cm
Correct Answer
A. .25cmExplanation
The given answer ".25cm" is most likely incorrect, as the length of the esophagus in adults is typically much longer than that. The esophagus is a muscular tube that connects the throat to the stomach, and its length can vary between individuals. On average, the length of the esophagus in adults is around 25-30cm. However, it is important to note that the exact length can vary depending on factors such as the individual's height and body size.Rate this question:
