Answer

Hypothalamus is part of hind-brain. So it becomes the part of CNS and is responsible for maintaining the homeostasis of the body. Also, it is responsible for secreting the hormones in the human body. So because of the hypothalamus there is close coordination between nerves and hormones. Also when adrenaline is released into the blood supply of oxygen increases to the muscle which helps to run and is made of nerves. So nerves and hormones together work in case of stress. Differences:
 
Nervous Control
Hormonal Control
1.
Nerves use electrochemical messages (impulses) to send messages throughout the body.
Hormones are released by glands and travel throughout the body to act on receptors on the target tissue.
2.
Nerves responses are much fast.
Hormonal responses are much slower.
