Brachial plexus at a glance

Brachial Plexus arise from C 5.6.7.8 and T1 nerve root.

If C4 nerve root involve with brachial plexus then its called Prefixed plexus

If T2 nerve root involve with brachial plexus then it's called postfixed.

Branches of the Root :

1.Nerve to Serratus Anterior / Long Thoracic nerve (C 5.6.7)

2.Nerve to Rhomboids / Dorsal Scapular nerve (C 5) 

Branches of the trunk :

1.Suprascapular nerve (C 5.6)

2.Nerve to subclavius (C 5.6)
