Explanation / Answer

1)cervical plexus are the plexus of anterior rami of first 4 cervical spinal nerves arise from first 4 cervical segments(C1-C4)

Additionally there are two branches formed by the posterior roots of spinal nerves:

brachial plexus:

these are the plexus of anterior rami of lower cervical nerves(C5-C8) and first thorasic nerve(T1) arise from lower cervical and 1St thorasic segment.

C5 AND C6-upper trunk

C7-middle trunk

C8-T1- lower trunk

divisions:

anterior division

posterior division

cords:

these are named by position of auxillary artery

posterior cord(C5-C8,T1)

lateral cord(C5-C7)

medial cord(C8,T1)

Phrenic nerve:

it originates from C3-C5 and inervate the muscle of diaphragm and receive sensory information from pericardium

axillary nerve inervation:

muscles

triceps of brachi,deltoid muscle,teres minor
