Q

Are the fibers of the spinal accessory nerve that innervate the trap and the SCM motor or sensory?

A

Motor

19
Q

Does damage to the Accessory nerve in the trap damage the SCM muscle? Or vice versa

A

Nope- they are different branches because the trap is posterior and the SCM is anterior
-to damage both of the muscles you would have to have damage where the Accessory nerve originates
