Classes of myenteric neurones. LM, longitudinal muscle; CM, circular muscle; MP, myenteric plexus; SMP, submucous plexus; AN, ascending neurones; IN, intestinofugal neurones; DIN, descending interneurones; EPAN, enteric primary afferent neurones; EMN, excitatory motorneurones; IMN, inhibitory motorneurones; LMMN, longitudinal motorneurones. The secretomotor and vasomotor neurones in the myenteric and submucous plexuses are not labelled (modified from Costa and colleagues6).
