Assess and document motor function using motor scale from Motor fibers facilitate movement and provide nerve function to the muscles. Sensory fibers facilitate sensitivities to touch, temperature and other stimuli. They provide nerve function to the skin. A group of muscles that is innervated by the motor fibers that stem from a specific nerve root is called a myotome. An area of the skin that is innervated by the sensory fibers that stem from a specific nerve root is called a dermatome.

These patterns of myotome and dermatome are almost always identical from person to person. There are occasionally variances, but that is rare. This consistency allows doctors to treat nerve pain in patients. If a certain area is hurting, they know that it is attributed to a certain myotome or dermatome, whichever the case may be, and its corresponding nerve root.

Problems with nerve damage is often the result of stretching the nerve or compressing it. When the nerves are injured in specific areas like the lumbosacral or brachial plexus, it presents as sensory and motor deficits in the limbs that correspond to them.

Myotomes and dermatomes are used to assess the extent of damage. The floor of this pyramid is formed by the first part of the subclavian artery and within this pyramidal space lies the vertebral artery and the cervical sympathetic trunk with the stellate ganglion. In dissection of the neck, it should be noted that the cervical sympathetic chain lies on the lateral aspect of the longus colli muscle at the level of C6.

The phrenic nerve arises just above the carotid tubercle and descends vertically on the scalenus anterior muscle where it is overlapped by the lateral margin of the internal jugular vein. The longus colli muscle receives its blood supply from muscular branches of the ascending cervical artery and the inferior thyroid artery. The longus colli muscle is innervated segmentally by anterior rami of the C2 to C6 spinal nerves from the cervical plexus.

The longus colli muscle works synergistically with longus capitis and scalene muscles as a weak flexor of the cervical spine. The action of the muscle is assisted greatly by gravity and by the powerful sternocleidomastoid muscles.
