Follow the course of sensory and motor innervation of the larynx. Predict the functional consequences of damage to these nerves.

Trace the course of nerves through the neck noting especially: the sensory and motor branches of the cervical and brachial plexuses, their course and distribution in the neck and their relationship to major bony, muscular, or vascular landmarks in the region.
