Q

Why are T1, 2 7-11 atypical intercostal nerves?

A

T1 - first rib and shares in brachial plexus. No lateral cutaneous branch.
T2 - lateral cutaneous branch (intercostobrachial nerve) - runs in axilla, communicating with medial cutaneous nerve of arm
T7-T11 - pass between costal slips of diaphragm to anterior abdominal wall to supply muscles and skin and parietal peritoneum.

Typical emerge from their corresponding intervertebral foramen and run posterior of intercostal space.

Q

What are the 3 aortic fixed points of attachment and why are they important?

A

aortic valve, ligamentum arteriosum, behind crura of diaphragm

rest of aorta is free from attachment - serious deceleration injuries likely to cause trauma at these fixed points

  2. It can pass upward or downward in the chain and synapse in one of the other ganglia of the chain
  3. It can pass for variable distances through the chain and then through one of the sympathetic nerves radiating outward from the chain, finally synapsing in a peripheral sympathetic ganglion.
