It was very hard to find good images for these next 2. We did our best to ID them correctly.

However, look at Netter, 4th Ed., on plate 429 for a very good representation

We couldn’t find images of Acromial and Deltoid branches of the thoracoacromial artery

Identify

Identify

Thoracoacromial artery, pectoral branch

Identify

Omissions• Longissimus capitis m.• Laminae of vertebrae• Interspinous ligaments• Posterior internal vertebral venous plexus• Ventral ramus• Retromammary space• Acromial and Deltoid branch of Thoracoacromial artery• Dorsal scapula nerve and artery• Lumbar vertebrae• C7 and its spinous process

DOUBLE CHECK YOUR BPL FOR ANYTHING ELSE WE MAY HAVE MISSED

Tips

• Don’t use alternative terminology not on the BPL – the BPL is always right

• Read the question card VERY carefully

• Take as much time as you need

• Radiographs are free points – they tell you what images you are going to see

• You can review the paper BPL before the practical, after the written

ALMOST DONE!!!!

WITH BLOCK 1!!!

GOOD LUCK!!
