Coordination for the Human Body

Coordination in the human body
Within this assignment I will describe the roles of the CNS and endocrine system according to the coordination of the human body. In addition I will explain how the nervous and endocrine system coordination is integrated and analyse the roles of the sensory, nervous and endocrine systems in maintenance of the normal functioning of internal organs and structures.  
For the body to work correctly the brain and hormones have to work together sufficiently. The brain includes an interior of single nerve cells and vital chemicals which carries messages between the brain cells and the two parts of the brain, this allows the brain to communicate through the messages and chemicals passed. There are two messengers; the happy messengers and the sad messengers. Most nerve centres receive input from both of the messengers as long as the input is balanced. This works as if you’re sad, the sad messengers will send more serotonin to the brain which will input the happy messengers. The brain works in a cognitive way which includes the hippocampus which is the main memory structure and prefrontal cortex which is involved in decision making and providing the behaviours a human can carry out. These two parts of the brain work together to allow the messages been sent to the brain to be carried out. However stress can cause problems with the brains happy messengers. When life runs plain sailing the happy messages manage to keep up with the demand, but when too much stress is cantered on the brain, the happy messages begin to fall behind of their demand and fail to send their deliveries. Important nerve centres then receive most sad messages and the whole brain becomes distressed. This then determinates the state of brain chemical imbalance.  

This image shows where the hippocampus and the prefrontal cortex are positioned in the brain. Furthermore the amygdala is the centralizing for emotions, emotional behaviour and motivation. This structure...
