In addition to the Gasserian (semilunar) there are four ganglia connected with the trigeminal nerve. These are :-
(b) With the Superior Maxillary division-Meckel's (sphenopalatine) ganglion.
(c) With the Inferior Maxillary division-the otic and submaxillary ganglia. Each ganglion receives sensory, motor, and sympathetic roots, and each gives off small branches of distribution.
