What influences the nervous and endocrine systems on behavior?

Answer 1

A thorough discussion of how your body works best begins with an overview of your nervous and endocrine systems, as these two organ systems act as co-directors of all of the activities that occur in your body.

To put it simply, your nervous and endocrine systems continuously monitor the well-being of each of the billions of cells in your body, and they continuously take action through messenger systems to keep all of your cells as healthy as possible.

Though your nervous and endocrine systems share the director's seat of your body, they fulfil their roles in completely different ways.

Your nervous system senses and controls every part of your body through its many nerves. Sensory receptors located throughout your body constantly send information through nerves to your brain; your brain digests this information; your brain then decides on appropriate action, and executes the action by sending additional information out to the target cells through other nerves.

For example, if you accidentally touch a hot pan, sensory receptors register pain almost instantaneously, this information travels through nerves to reach your brain, your brain understands that your hand is in danger of being injured in its current position, and your brain sends information down other nerves that tells your muscles to jerk your hand away from the pan.
