Immune System Interactions with the Nervous System
By Anna
The Hypothalmous in the Brain, controlls temearature within the body. When a pathogen enters the body, your temperature goes up to kill the pathogen. Sometimes this rising of the temperature works to kill the Pathogen, and sometimes it doesnt. This is why if you are sick from a pathogen you sometimes get a fever. If it does kill the Pathogen then this makes the immune systems job easier. (There is no immune responce needed.) The brain contols the hole immune responce for the body. It tells the body where the Tcells, Bcells ect, are needed.
When you are stressed, and your brain is trying to deal with the stress, this can weaken the immune system. It gets weakened by your body focusing on something else other then keeping Pathogens away and the usual. Spicifically, your Tcell and Bcell levels can drop making the immune system weak. Another way that stress in the brain affects the immune system is that the adrenal glands gets stress messages from the brain and relase corticosteroid hormones into the blood. These hormones decrease antobodies and reduce lymphocytes, making the immune system weaker.
Hypothalmous= A collection of specialized cells that is located in the lower, centeral part of the brain.
