- Lesser occipital nerve - innervates lateral part of occipital region (C2 ONLY)
- Great auricular nerve - innervates skin near concha auricle and external acoustic meatus (C2&C3)
- Transverse cervical nerve - innervates anterior region of neck (C2&C3)
- Supraclavicular nerves - innervate region of supraspinatus, shoulder, and upper thoracic region (C3,C4)
- Muscular
- Ansa cervicalis (loop formed from C1-C3), etc. (geniohyoid (C1 only), thyrohyoid (C1 only), sternothyroid, sternohyoid, omohyoid)
- Phrenic (C3-C5 (primarily C4))-innervates diaphragm and the pericardium

Famous quotes containing the word branches:
“We are nothing but ceremony; ceremony carries us away, and we leave the substance of things; we hang on to the branches and abandon the trunk and body.”
—Michel de Montaigne (1533–1592)
“...there is hope for a tree, if it is cut down, that it will sprout again, and that its shoots will not cease. Though its root grows old in the earth, and its stump dies in the ground, yet at the scent of water it will bud and put forth branches like a young plant. But mortals die, and are laid low; humans expire, and where are they?”
—Bible: Hebrew, Job 14:7-10.
“A woman is a branchy tree
And man a singing wind;
And from her branches carelessly
He takes what he can find.”
—James Kenneth Stephens (1882–1950)
