The brief description here given applies especially to the sym- pathetic system of the neck and trunk. Representatives of the system are also found in the head, in the form of a series of ganglia connected with the trigeminal and facial nerves and known as the ciliary, spheno-palatine, otic, and submaxillary ganglia; and, as will.
