larval Eh neurosecretory neuron

ID: FBbt_00006028

Larval neuron that expresses eclosion hormone (Eh). There is one of these in each hemisphere, with its soma in the tritocerebrum (Horodyski et al., 1993; Siegmund and Korge, 2001). Branches extend anteriorly and posteriorly, spanning the entire length of the central nervous system (Horodyski et al., 1993; Siegmund and Korge, 2001). It synapses onto other ring gland projection neurons and neurons in the ventral nerve cord that may be involved in ecdysis motor programs (Huckesfeld et al., 2021). Another branch extends posteriorly, then anteriorly, and follows the nervus corporis cardiaci to the ring gland, where it has peptide release sites in the corpus cardiacum and the aorta (Siegmund and Korge, 2001; Huckesfeld et al., 2021). It releases Eh around the time of ecdysis (Horodyski et al., 1993).
