Using the Foerster dermatome map below, label the dermatomes of the arm.
The Musculocutaneous nerve supplies the Biceps Brachii Triceps Brachii( Biceps Brachii, Triceps Brachii ) and originates from the C5 and C6 C4 and C5 C6 and C7 C7 and C8( C5 and C6, C4 and C5, C6 and C7, C7 and C8 ) spinal nerves.
Posteriorly, the neck and scalp skin is mainly supplied by the posterior anterior( posterior, anterior ) rami of spinal nerves C2 C1 C3( C2, C1, C3 )-C8
