842 THE NERVOUS SYSTEM OF THE OX 
the lateral border of the fiexor tendons, gives a branch to the suspensory ligament 
and to the lateral small digit, and continues along the lateral face of the lateral 
digit as the lateral plantar digital nerve (N. dig. plant. lat. dig. IV). 
The sympathetic system closely resembles that of the horse in its general 
arrangement, and only a few differential features will receive attention. The 
anterior cervical ganglion is closer to the cranial base and is thicker than in the 
horse; its branches to the carotid and cavernous plexuses are large, and no con- 
nection is formed with the spinal accessory nerve. The cervical trunk is smaller

than in the horse, and arises by two or three bundles from the anterior cervical 
ganglion behind its middle. The posterior cervical ganglion is distinctly separable 
from the first thoracic; the latter is large. There are thirteen pairs of thoracic 
ganglia. The great splanchnic nerve begins at the fifth or sixth thoracic ganglion 
and receives branches from the succeeding ones; it is commonly difficult to dis- 
tinguish clearly from the thoracic trunk. The small splanchnic nerve is repre- 
sented apparently by filaments which go from the first lumbar ganglion to the 
adrenal plexus and the eceliac ganglion. The coeliac ganglion is rounded and lies 
on the cceliac artery. The anterior mesenteric ganglion is longer and is closely
