Yes, peripheral nerves connect the spinal cord to the limbs and other parts of the body. These nerves carry messages between the brain and the rest of the body, allowing for movement and sensation.
Why a peripheral nerve such as the sciatic nerve can contain nerve fiber from several spinal nerves?

What nerve branch extends to the upper muscles of the cheek?
The nerve branch that extends to the upper muscles of the cheek is the buccal branch of the facial nerve (cranial nerve VII).

What is the nerve supply to the larynx?
The larynx receives its nerve supply from the vagus nerve (cranial nerve X). Specifically, the recurrent laryngeal nerve innervates the intrinsic muscles of the larynx involved in phonation, while the external branch of the superior laryngeal nerve supplies the cricothyroid muscle.
