What is the diaphragm
Skeletal muscle
What type of muscle is the diaphragm
Skeletal muscle
What is the phrenic nerve made of
The anterior rami of C3, C4, C5
What does the long thoracic nerve supply
Serratus Anterior
Paralysis of the long thoracic nerve results in
Winged scapula
What are the 3 blood vessels on either side of the sternum
Internal thoracic artery (anterior intercostal arteries branch from this) and a pair of veins
What branches from the internal thoracic artery?
Anterior Inter-coastal arteries
What is the most inferior part of the pleural cavity
Costodiaphragmatic recess
The most inferior part of the costodiaphragmatic recess
Costophrenic angle
Fluid build-up causes on CXR?
Blunting of angles and a fluid level
Costophrenic angle and fluid?
Blunts the angle
The ‘tongue’ of the superior lobe of the left lung
Lingula
Where is the cephalic vein located
Delto-pectoral groove
What level does the trachea bifurcate?
Sternal angle (2nd rib)
and T4/5 (intervertebral disc)
Where do the inguinal ligaments attach
Between ASIS and pubic tubercle
Midpoint of the inguinal ligament?
Deep ring
Where is the deep ring with regards to the inguinal ligament
Midpoint
Describe a direct inguinal hernia
A bit of peritoneum is forced through the posterior wall of the inguinal canal and DIRECTLY out of the SUPERFICIAL ring
Describe an indirect inguinal hernia
A bit of peritoneum is forced through the DEEP, into the inguinal canal, and then out of the superficial ring
Direct vs indirect inguinal hernia test
Reduce the hernia, occlude the deep ring with the fingertip and ask the patient to cough
If reduced, a direct hernia will…
Reappear as it does not need to pass through the deep ring to get out of the scrotum
If reduced, an indirect hernia will…
(Shy away) not reappear as it needs to pass through the deep ring to get out of the scotum
