. 2 and 3. In both these dia-grams the nerve processes have been drawn with redcolor, so as to distinguish them easily from the protoplas-matic processes. For both figures the same neuron Ahas been chosen. Text-Figure 2 shows this neuron Aunder the influence of excitation from the neurons B andC. Text-Figure 3 represents neuron A under the influ-ence of inhibitory action from the neuron D. Chapter II. ANATOMY OF THE GANGLIA TED CORDS. We shall begin the detailed anatomical account with adescription of: The two great gangliated cords. It is customary to distinguish four parts or portions ofthe great gangliated cord: the cervical, the thoracic, thelumbar, and the sacral. We shall describe these in thisorder leaning our description on that given by Thane(Quains Anatomy). I.—Cervical Part of the Gangliated Cord.—In the neckthe gangliated cord is placed deeply behind the greatblood vessels of the neck, being embedded in the fasciawhich forms the posterior part of the carotid sheath.

The cervical part of the gangliatedcord consists of three ganglia, the first of which is placednear the base of the skull, the second in the lower partof the neck, and the third close to the head of the first rib. 1.—Upper or Superior Cervical Ganglion.—This is thelargest ganglion in the great sympathetic cord. It issituated on the rectus anticus major muscle, opposite thesecond and third cervical vertebrae, behind the internalcarotid artery, and to the inner side of the pneumogastricnerve. It continues above into an ascending branch andtapers below into the connective cord so that it usuallyhas a fusiform shape, but in this there is considerablevariation, the ganglion being occasionally short andbroad, and sometimes constricted at intervals. We mustnow consider the various connections of this ganglion. a. —Conne
