What's the difference between ganglion and interganglionic?
Ganglion
Definition:

Interganglionic
Definition:
(a.) Between and uniting the nervous ganglions; as, interganglionic cords.
Example Sentences:
(1) Interganglionic strands composed mainly of long processes were unstained.

(3) Slow EPSPs were evoked by repetitive stimulation of the interganglionic connectives.
(4) The oscillatory interneurones are connected both intra- and interganglionically to form a topologically complex intersegmental network of concatenated ring circuits that possess the feature of recurrent cyclic inhibition.
(5) In contrast, atrial pacing or right interganglionic nerve stimulation augments chronotropism such that myocardial oxygen consumption and efficiency are unchanged.
(6) These morphological features of the ganglion cells in airways and the trajectories of their axons correspond to known features of their physiology: i.e., the axon of a ganglion cell travels unidirectionally toward the adjacent ganglion and arborizes there, providing anatomical evidence of communication between ganglia via the interganglionic nerve trunk; and the spiking and nonspiking neurons possess similar morphological features that are typical of ganglion cells described in other systems, such as in the myenteric plexus.
(7) Most of the ganglion cells received multiple inputs from axons entering the individual ganglia in several different interganglionic fibre tracts.
(8) Large and small varicose fibers stained in the neuropile of all the above-mentioned ganglia but also in interganglionic connectives and segmental nerves.
(9) Indirect stimulation via the rami communicantes or the interganglionic nerves of the sympathetic chain evoked a graded synaptic response which could lead to the discharge of one or more action potentials.
(10) Although 5-HT is a mediator of slow excitatory postsynaptic potentials evoked by stimulation of interganglionic connectives, the precise role it plays in the physiology of the gut is unclear.
