PTM - 2 Flashcards
Factors contributing to lower oesophageal sphincter preventing reflux
Acute angle of entry of oesophagus (angle of his)
Phreno-oesophageal ligament encircling the GOJ
Prominent mucosal folds in GOJ
What is achalasia
Oesophageal dysmotility
caused by disordered coordination of the perstaltic action of smooth muscle + non-relaxation of LES (loss of myenteric plexus)
Manometry findings of achalasia
High pressure in lower oesophageal sphincter
Failure to relax lower oesophageal sphincter on swallowing
Aperistalsis
Where do ophthalmic veins drain
Cavernous sinus
Clinical fx of orbital blow fracture
Infraorbital sensory loss
Enophthalmos
Diplopia
Orbital emphysema
Posterior relations of kidney
Diaphragm
Psoas
Quadratus lumborum
What lies anterior to IVC at its origin
Right common iliac artery
What ligament joins coracoid to clavicle
Coracoclavicular ligament made off conoid and trapezoid ligaments
Under which ligament does supraspinatous get impinged
coracoacrominal ligament
Boundaries of posterior mediastinum
Superior = T4/5
Anterior: pericardium
Posterior: T5-T12 body
Lateral: pleura
Inferior: diaphragm
Path of azygous vein
Formed by union of first ascending lumbar and subcostal vein below diaphragm, right of vertebral column.
Enters diaphragm through aortic hiatus
Ascends in the posterior thorax
Empties into SVC
Tributaries of azygous vein
Hemiazygous vein (joins at T8)
Accessory hemiazygous vein (Joins at T7)
Path of hemiazygous vein
Forms from left ascending lumbar + left subcostal
Ascends left of vertebral column before entering azygous at T8
Path of accessory hemiazygous vein
Formed by the union of 4th-8th left intercostal vein
Descends on the left before draining into azygous at T7
Path of sympathetic trunk
Exits the skull through carotid canal
Travels lateral to vertebral column from base of skull to coccyx
Passes anterior to the neck of the first rib
Passes behind median arcuate ligament of the diaphragm
Lowest cervical and upper thoracic join to form stellate ganglion
Thoracic ganglia give greater, lesser and least splanchnic nerves
Path of thoracic duct
Formed at the confluence of left and right lumbar lymph trunks and left and right intestinal lymph trunks (cisterna chyli)
Crosses diaphragm through the aortic hiatus at T12
Crosses from right to left at T4/5
Empties into the angle between internal jugular and subclavian vein
Where does the right thoracic lymphatic trunk drain into?
Into the right brachiocephalic vein
What does right lymphatic trunk drain?
Right upper limb
Right lung
Right breast
Right head+neck
Between which layers is the intercostal bundle found
Between innermost intercostal and internal intercostal
