Document Summary
Endocrine cells respond directly to a stimulus. Hormone gets to tc and specific receptor. Stomach contents enter duodenum low ph stimulus. Need to be neutralized release of basic bicarbonate (has high ph) Needs to molt shed old exoskeleton and secrete a new one. This process is regulated via endocrine system. Levels of jh ecdysteroid causes in size + molting. As larva grows, it molts, but still juvenile (no metamorphosis) Lowest jh: pupa molts adult via metamorphosis. Doesn"t let them to reach the age of reproduction insect population. Hypothalamus can cause direct or indirect control of all hormone secretion boss! Connected to pituitary gland via portal vessels. Serves as a link between endocrine system + nervous system. Receives information from endocrine system + body"s nerves. Released into pituitary portal vein anterior lobe of pituitary. Production of adh + oxytocin peptide hormones produced by cell bodies of neurons. Travel down the axon posterior pituitary gland.
