 fulmona'res (2 or 3 in number.) Posterior pulmona'ris. CEso- 

 fhagea'les. Gastric branches. Part in. supplies motor fila- 

 ments to sterno-mastoideus and trapezius. The accessory 

 part arising from lateral tract of cord, the spinal portion as

.9thorHyp:glos'SUS. From floor of medulla. Is the motor ol the 

 tongue. Out through anterior candyloid foramen to supply the 

 genio-hyoid, genio-hyo-glossus, hyo-glossus, stylo-glossus, 

 thyro-hyoid, sterno-hyoid, omo-hyoid, and sterno-thyroid 

 muscles. Is deep-seated (beneath internal carotid), but finally 

 curves over externally to the carotid to muscles for distribution. 

 Has branches of communication with pneumogastric, sympa- 

 thetic, ist and 2d cervical and gustatory. Dcscen'dens ncfni 

 (on carotid sheath), joining with ad and 3d cervical. Thyro- 

 hyoid branch. Muscular branches. 



CiRVICA'LES: each increase in size from i&t to 5th ; 8 pairs 

 in all. Have anterior and posterior branches, the latter hav- 

 ing ganglionic enlargements. The ist, or sub~occipital t (ante- 

 rior branch) has exit between atlas and occiput, the remain- 

 ing 7 between their respective vertebrae. The 4 upper (ante- 

 rior branches) unite to form the cervical plexus; the 4 lower 

 (anterior) with the ist dorsal form the brachial plexus.
