What are some similarities between nerves and hormones?

A neuron is a nerve cell, the basic building block of the nervous system. The neuron is a specialized cell, which functions by transmitting information throughout the body. Hormones are chemical messengers that are secreted directly into the blood by the specialized glands called the endocrine glands.

The biggest difference between the two is that the nervous system uses electrical impulses to send signals through neurons, whereas the hormonal system uses chemical messengers transported into blood plasma to target cells. While endocrine system is slow, nervous impulse is immediate/rapid. Hormones are transported chemically through blood, nervous impulses are transported electrochemically through nerve fibres. Hormones affect different organs of the body and has a widespread effect, while nervous impulses afeect only a particular part of the body. Hormonal effect is long lasting whereas nervous effect is short lived. Hormones can bring about a metabolic change but nervous impulse impulses cannot bring about a metabolic change.
