B. PHYSIOLOGICAL. 
The N. glosso-pharyngeus is the sensory nerve of the pharynx; it is 
the special sense nerve of taste; it controls deglutition, and when abnorm- 
ally irritated excites an inverted muscular action in the muscles of the 
stomach and esophagus, inducing vomiting ; it does not seem to be sus- 
ceptible of painful sensations. 
EXPLANATION OF THE DIAGRAM. 
The diagram is not drawn toa scale. It has been the author’s aim to 
present in definite form the principal structures and relations, combining 
simplicity and clearness. Aur., the auricular branch trom the jugular 
ganglion of the vagus nerve to the geniculate ganglion of the facial. 
This nerve crosses the ectal surface of the glosso-pharyngeus just ventrad 
of the root ganglion. Car., the anastomotic nerve to the carotid plexus 
around the ectal origin of the A. occipitalis. Ehr., the ganglion Ehren- 
ritteri, or ganglion of the root. Eus., the branch which forms with the 
sympathic a plexus upon the eustachian tube. Gang., the plexus gangli- 
formis, or plexus nodosus. Gen., the position of the geniculate ganglion 
of the facial nerve. Inf., the ganglion inferius or ganglion of the trunk 
of the vagus nerve. Jug., the ganglion jugulare or root ganglion of the 
vagus. M. phar., the muscular ramus to the pharyngeal constrictors. 
Pal., the branch: of the pharyngeal nerve which is distributed to the 
mucosa in the region of the soft palate, and possibly to the palatal mus- 
cles. Papillw, the terminal filaments of the papillary ramuli which are 
given to the long papille characteristic of the dorsal surface of the base 
of the tongue. Pe., the ganglion petrosum or ganglion of the trunk. 
Pe. maj., the branch of the tympanic nerve which becomes one of the 
roots of the great superficial nerve. Pe. min., the branch of the tym- 
panic which becomes the small petrosal nerve and terminates in the otic 
ganglion. Phar., the pharyngeal ramus which joins the pharyngeal 
nerve from the vagus to form the pharyngeal plexus. Phar. muc., the 
rami which form the plexus over the pharyngeal mucosa, Phar. vagus,
