part of adult deutocerebrum synaptic neuropil domain adult periesophageal neuropils cantle PONPp FBbt:00045051 The name 'cantle' was taken from the seat-back part of the horse-riding saddle. The cantle corresponds to the ventroposterior part of the ventromedial protocerebrum (VMP) of Chiang et al. (2011) and to the posterior periesophageal neuropils (Ito et al., 2014). VFB:FBbt_00045051 fly_anatomy.ontology posterior perioesophageal neuropils VMP PENPp A small, bilaterally paired, triangular synaptic neuropil domain that lies at the posterior end of the saddle. It is clearly demarcated by glial boundaries. CAN
