Question 5

Different levels of openings in the diaphragm

Answer 5

Openings of diaphragm: I8 10eggs At12 (pneumonic)
Venacaval opening: In central tendon at T8
structures passing through: IVC, Right phrenic nerve
Oesophageal opening: In muscular part at T10
structures passing thorugh: Oesophagus, Right & left vagus nerve, oesophageal branch of left gastric artery
Aortic opening: Between the crus of diaphragm at T12
Structures passing through: Aorta , Azygous & hemiazygous vein, Thoracic duct.
​Note: Left phrenic nerve directly pierces the diaphragm

Question 6

Unpaired sinuses

Answer 6

Unpaired sinuses : (mnemonic: SIS-BPO)
1 Superior sagittal sinus.
2. Inferior sagittal sinus.
3. Straight sinus,
4. Occipital sinus.
5. a Posterior intercavernous sinus.
b. Anterior intercavernous sinus.
6. Basilar venous plexus.

Question 7

Superior Sagittal sinus continues as

Answer 7

Right transverse sinus

Question 8

Inferior transverse sinus continues as

Answer 8

Inferior sagittal sinus continues as Straight sinus
Straight sinus receives Galons vein (great cerebral vein of galon)
After receiving galons vein it continues as left transverse sinus

Question 9

Right & left transverse sinus continues as

Answer 9

Sigmoid sinus which continues as IJV

Answer 10

Cavernous sinus
Inferior petrosal sinus
Posterior inter cavernous sinus
