Document Summary

Prothoracic gland produces ecdysteriod, travels in blood to the: If the amount of juvenile is high, when the animal moults, they will stay a juvenile. Low levels of juvenile hormone, they will become an adult. Beta cells in the pancreas detect high glucose and release. Glycogen from the blood glucose, lowers glucose level. Alpha cells in the pancreas detects low glucose and release. Glucagon and enters the blood stream to the target organ: Glycogen breakdown releasing glucose into blood, raise glucose level. Neurohormones from hypothalamus -hormones from nervous tissue - neurons. Tropic effects - goes to gland a cause a release of another hormone - hormone cascade -ptth. Nontropic effects - goes to target and has an effect - insulin. Thyroid releasing hormone trh - trophic, goes to. Thyroid stimulating hormone tsh - trophic, goes to. Displacement an egg from the nest, - stimulus. Reach out, grab egg, and roll it back to the nest -fixed action potential.
