Explanation :
Tributaries of Azygos vein
- Right superior intercostal vein
- Right posterior intercostal veins (5 to 11)
- Hemiazygos vein
- Accessory hemiazygos vein
- Right bronchial vein- last tributary that joins Azygos vein just before its termination.
- Esophageal, mediastinal and pericardial veins.
Q.4
Azygos vein -
A. Arches the groove of the left lung
B. Opens into inferior vena cava
C. Formed by arch of aorta
D. Ascends through the aortic opening in the diaphragm
Explanation :
Azygos vein is formed by
- Subcostal veins
- Ascending lumbar veins
- Lumbar Azygos veins
It crosses the diaphragm on the right side, by piercing the right crus or the aortic opening.
At the level of T4 vertebra, it arches over the hilum of right lung.
It opens into the superior vena cava.
Q.8
All are true about intercostal nerve except -
A. The relationship from above downward is nerve, vein, artery
B. T4, T5, T6 are called typical intercostal nerve
C. Lie between the innermost intercostal and internal intercostal muscle
D. T7 to T11 supply the abdominal wall
Explanation :
The relation of intercostal nerves in the intercostal groove, from above downwards is vein, artery, and nerve.
- Intercostal nerves supply the intercostal space.
- T1-T2 also supplies the upper limb.
- T3-T6 only supplies the thoracic wall. So called as typical intercostal nerves.
- T7-T11 also supplies abdominal wall.
- T12 also supplies abdominal wall and skin of buttocks.
Q.9
Inferior most structure of right hilum is :-
A. Bronchus
B. Inferior pulmonary vein
C. Pulmonary artery
D. Inferior bronchial vein
Explanation :
Structures at the hilum- Superior to inferior
- Left lung
o Pulmonary artery
o Bronchus
o Inferior pulmonary vein
- Right lung
o Eparterial bronchus
o Pulmonary artery
o Hyparterial bronchus
o Inferior pulmonary vein
Q.12
Rectus adominis is inserted into -
A. Xiphoid process
B. Median raphae
C. Linea alba
D. 1-4 ribs
Explanation :
Rectus abdominis attachment
- Origin
o Lateral head- Pubic crest
o Medial head- Anterior pubic ligament
- Insertion
o Xiphoid process
o Costal cartilages- 5,6,7
Q.13
Which of the following is true about splenic artery?
A. Smaller than left gastric artery
B. Gives short gastric arteries along the fundus
C. Curves around the fundus
D. Arises from abdominal aorta
Explanation :
Splenic artery branches from the celiac artery and follows a course superior to the pancreas.
Splenic artery gives off branches to the stomach and pancreas before reaching the spleen.
The short gastric artery is through the upper part of the greater curvature of stomach and fundus of the stomach.
Some other branches are: Branch to the pancreas, Left gastroepiploic, Posterior gastric.
Q.16
True about inguinal canal -
a) It is an intermuscular canal
b) Superficial inguinal ring is situated superior and lateral to pubic tubercles
c) Deep inguinal ring is superio-medial to attachment of rectus abdominis
d) In male vas deference passes through it
A. AD
B. ABC
C. ACD
D. ABCD
Explanation :
Superficial inguinal ring is supero-medial to pubic tubercle.
Deep inguinal ring lies lateral to rectus abdominis, as an opening in fascia transversalis.
Q.18
True about deep inguinal ring is -
A. Defect in fascia transversalis
B. Commonest site of direct hernia
C. Present medial to inferior epigastric artery
D. Lies an inch above the mid inguinal point
Explanation :
Deep inguinal ring lies lateral to rectus abdominis, as an opening in fascia transversalis.
- It lies 1.25 cms above mid inguinal point.
- Inferior epigastric vessels lie medial to the deep inguinal ring.
- Through the deep inguinal ring, indirect hernia enters the inguinal canal.
