Sternocleidomastoid
Trapezius
Posterior cervical triangle
Identify the muscles of the neck and indicate their major actions and sources of innervation. Indicate the relationship of each of the muscle groups to the layers of
deep fascia in the neck.

Actions of intrinsic laryngeal muscles
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.

Trace the flow of arterial blood from the aorta through the neck including vessels that pass through the neck without branching and those that send branches to viscera and muscles of
the neck.
Two main arteries are found in the neck: Subclavian and branches and Carotid
