transverse foramina
immediately caudal to the wing of the atlas and emerges between the cleidomastoideous and omotransversarius
2nd pair of cervical spinal nerves
Cranial nerve XI is also the what nerve

the 2 major body cavities that are separated by the diaphragm
thoracic cavity
abdominopelvic
thoracic cavity dorsal boundary
T1-T13
thoracic cavity ventral boundary
8 sternebrae
thoracic cavity lateral boundary
13 pairs of ribs and 2 costal arches
diaphragm is what type of muscle
skeletal – under voluntary control
where to the lumbar right and left crura of the diaphragm attach
bodies of the 3/4th lumbar vertebrae
four diaphragm openings
- lumbocostal arches - not a true opening
- aortic hiatus
- esophageal hiatus
- caval foramen
aspiration of pleural fluid from the abdomen
thoracentesis
can be approached without risk to pleural cavity clinically
diaphragmatic line of pleural reflection
where the vena cava passes the diaphram
plica vena cava
clinical issue with diaphragm
diaphragmatic hernias
prevents frictional irritations in viscera
serous liquid filling serous cavities
3 serous cavities in the thoracic region
pleural (right and left)
pericardial
serous cavity in the abdomen
peritoneal
pleural effusions
liquid accumulation in thoracic cavity
