branches of the pneumogastric and glossopharyngeal nerves, and by their union with these nerves the pha- ryngeal plexus is formed. Branches emanating from the plexus are distributed to the muscles and mucous mem- brane of the pharynx. One or two filaments pass from these branches to the superior and external laryngeal nerves. e.—Laryngeal Branches.—These branches anastomose with twigs from the inferior laryngeal to form the so- called laryngeal plexus. /.—Branches to Blood Vessels.—The nerves which ramify on the arteries (nn. carotici externi) spring from the front of the ganglion and twine around the trunk of the external carotid artery (plexus caroticus externus). They are also prolonged on the branches of the artery, forming upon them slender plexuses which are named after the arteries they accompany. From the plexus on the facial artery is derived the filament which forms the sympathetic root of the submaxillary ganglion, and from that on the middle meningeal artery twigs are described as extending to the otic ganglion, as well as to the geniculate ganglion of the facial nerve (external superficial petrosal nerve). One filament descends from these nerves to the parotid gland. Ganglia of microscopical size are fre- quently met with in the vascular plexuses, and several larger ones of more constant occurrence have been described, such for instance as the temporal ganglion. —Upper {or superficial) Cardiac Nerve.—Each of the cervical ganglia of the sympathetic usually furnishes a cardiac branch, the three being named respectively, the upper, middle and lower cardiac nerves. These branches are continued singly or together, to the large prevertebral thoracic plexus (cardiac plexus) to the formation of which
