Solution(By Examveda Team)

Corpora codiaca secretes the Hormone in insect.
The neurosecretory cells and the corpus cardiacum, a transformed ganglion closely associated with the heart, produce a peptide, called the prothoracicotropic hormone (PTTH), which stimulates the prothoracic gland to produce ecdysone, a sterol hormone.
CC is the major neurohemal organ in insects and releases a large number of neuropeptides.
