Figure 2: Cranial Nerves
& Functions
The twelve pairs of cranial
nerves are attached to the base
of the brain and travel through
various openings in the skull to
reach specific areas of
innervation
Figure 3: Nerves of Upper Body
The brachial plexus is formed
by the ventral roots (green) of
spinal nerves C5-T1 Proximally
to distally, they then form
3 trunks (superior, middle, and
inferior [blue]), 3 anterior and
3 posterior divisions (purple),
3 cords (lateral, posterior, and
medial [red]), and 5 terminal
branches (yellow)
