8 pairs
14. The accessory nerve has a dorsal and a ventral branch; which cervical muscles are innervated by each?
Dorsal branch-trapezius
Ventral branch-sternocephalicus
15. Where are the transverse nerve of the neck and the cervical branch of the facial nerve located?
transverse nerve of the neck-?near C2?

cervical branch of the facial nerve-runs with the external jugular vein
16. Identify the origin of the phrenic nerve and brachial plexus
phrenic n.-ventral branches of C5, C6, and C7

brachial plexus-ventral branches of C6, C7, C8, T1 and T2
-deep to the scalenus muscle
17. Identify the major vessels supplying the cervical musculature.

22. What is the significance of the omohyoideus in the horse?
-it supposedly "protects" the common carotid a. from deep venipuncture by acting as a barrier
