Motor cranial nerves
help control muscle movements in the head and neck.
What nerve controls head and shoulder movement?
An unusual nerve that contains both cranial and spinal roots

provides motor function (movement) to two muscles essential to neck and shoulder movement, the sternocleidomastoid (SCM) and the trapezius, as well as to the larynx (voice box) and other structures in the throat.
What happens if cranial nerve 1 is damaged?

enables tongue movement. It controls the hyoglossus, intrinsic, genioglossus and styloglossus muscles.
Why is the Trochlear nerve unique?

What is the function of trigeminal nerve?
The trigeminal nerve is the part of the nervous system responsible for
sending pain, touch and temperature sensations from your face to your brain
