Editing Cervical plexus (section)

=== Branches ===
The cervical plexus has two types of branches: [[Cutaneous innervation|cutaneous]] and muscular.<ref name=":0" />
*Cutaneous (4 branches): 
**[[Lesser occipital|Lesser occipital nerve]] - innervates the skin and the scalp posterosuperior to the auricle (C2)
**[[Great auricular nerve]] - innervates skin near concha auricle ([[Pinna (anatomy)|outer ear]]) and [[external acoustic meatus]] ([[ear canal]]) (C2-C3)
**[[Transverse cervical nerve]] - innervates anterior region of neck (C2 and C3)
**[[Supraclavicular nerves]] - innervate the skin above and below the clavicle (C3-C4)<ref>Clinically Oriented Anatomy by Moore and Dally's</ref> {{Clarify|date=July 2023|reason=Clarify preceeding reference - which edition?}}
*Muscular
**[[Ansa cervicalis]] - a loop formed by C1-C3 that supplies most infrahyoid (a.k.a. "strap") muscles ([[sternothyroid]], [[sternohyoid]], [[omohyoid]] muscles) etc.
**[[Thyrohyoid branch|Nerve to thyrohyoid]] - fibres from C1 that run with the [[Hypoglossal nerve|hypoglossal nerve (cranial nerve XII)]] and do not participate in the formation of the [[superior root of ansa cervicalis]], instead continuing for some further distance to reach and innervate the [[thyrohyoid muscle]] and the [[geniohyoid muscle]].
**[[Phrenic]] (C3-C5, but mostly C4) - innervates [[thoracic diaphragm]] and the [[pericardium]].
**Segmental branches (C1-C4) - innervate [[scalenes|anterior and middle scalene muscles]]
**[[Levator scapulae|Levator scapulae muscle]] (C3-C4) (also innervated by [[dorsal scapular nerve]] (C5) of the [[brachial plexus]])
