I have been given this complicating essay on the nervous system and endocrine system. We have to compare and contrast the roles between the two. What does this actually mean?

Also, does anyone know of examples of combinatorial control as well as nervous and endocrinal control individually.

Thankyou

Compare and contrast!
Nervous: Immediate effect, rapid, electrical, travels down neuronal axons, target determined by pathway, allows integration and inhibition.

Hormonal: Diffuse effect, secreted by ductless glands, chemical messengers, carried in the bloodstream, target organ depends on te presence of specific receptors...

Both can bring about physiological changes and both end up doing something to specific receptor molecules on target cells. Both may initiate the releae of secondary messanger molecules within the cell...

As for systems controlled by both - try heart rate, vasodilation and venoconstriction. There are more...
