the muscles and integuments of the neck. This nerve is supposed to be 
compound, but essentially motor, and has been termed “ ie respiratory 
nerve of the neck.” 
9. THE LincuaL NERVE; HypocuossaL Nerve. NintH Parr. This 
arises from the medulla oblongata, by several fasciculi, whose roots spring 
from the fissure which separates the corpus pyramidale from the corpus 
olivare; these unite into two or three trunks, which ultimately coalesce 
into one which passes through the anterior condyloid foramen of the occi- 
pital bone, to be distributed to the muscles of the tongue. As it passes 
across the neck, below the digastric tendon, it gives off a considerable 
branch, the descendens collt or noni, to the omo- capi sterno-hyoid, and thy- 
roid nee
