Document Summary
Endocrine system: (the molting part: signal: neurohormonal signaling systems- a combination of two events: dermal gland cells become columnar and divide. Endocrine signaling is done when the growth of insect is needed. Stretch receptors in the gut tells the insect that it needs to molt to allow more eating. Epigenetics is switching from producing exoskeleton to molting the exoskeleton (which means mass production of n. acetylglucosmaine for the new one). First set of genes to create exoskeleton, second set of genes for cellular maintenance, first set of genes turned back on, to create the nag and all the other molecules associated with it. Sequence of events of molting (for all insects): signal starts from an unknown source (either blood or another neuron). One signal is done by eating a meal (stretch receptors). Neurosecretory cells: neurosecretory cells: cells found in the brain.
