Diaphragm: Nerve supply

Submitted by jyo on Thu, 21/08/2008 - 17:06

"3 from 3"

Think: 3 roots from C3 ie., C3, C4 (dominant) and C5.

These nerve roots unite to form the phrenic nerve which innervates the diaphragm.

Damage to the phrenic nerve will thus lead to diaphragmatic paralysis.

C 3,4,5 Keeps the diaphragm alive!

The diaphragm is supplied by the phrenic nerve from segments C3-5 (C4 dominant). Damage to the phrenic nerve leads to diaphragm paralysis

C3, 4 and 5 keep the diaphragm alive! Works for me.
