how does nervous system differ from the endocrine system in forming control and coordination in animals?

nervous system controls the body and endocrine system releases hormones in body.

Answer:
The nervous system acts by generating and transmitting electric currents along the neurons (nerve cells). The endocrine system acts by releasing chemicals (hormones) to the circulatory system.
Explanation:
The nervous system consists of the central nervous system (the brain and spinal cord), and the peripheral nervous system (the nerve fibers which come out from the brain and spinal cord). The brain gets the messages from the sensory organs through nerve fibers, then analyzes and responds. After processing it sends messages to the peripheries, again through nerve fibers. There are different nerve fibers to take messages to the brain (afferent nerve fibers) and out of the brain (efferent nerve fibers). All the messages are transmitted as electric currents and therefore very quick, within milliseconds. Using this electrochemical method the central nervous system controls and coordinates the entire body.
The endocrine system consists of a number of glands (e.g. Hypothalamus, Pituitary, Adrenal) which produce chemicals called hormones (e.g. Adrenaline, Oestrogen, Testosterone). Hormones carry the messages to the organs through the blood stream. For that, the glands should produce, store, and release the hormones as needed. Also the hormones have to travel through the blood flow. So the endocrine system act through a chemical system and is slower than the nervous system.
