The Hypothalamus is the part of the brain that responds to stress.
When the is a 'Stressor' in the enviroment, signals are sent to the hypothalumus. This triggers two processes within the body.
1. Sympathomedullary Pathway:
This is where the Hypothalamus triggers activity in the sympathetic branch of the autonomic nervous system. (which is a branch of the peropheral nervous system.) This branch becomes more in use when the body is stressed and is using energy.
These affects the body in a few ways, including:
- High blood pressure and heart rate
- Digestion slows down or even stops
- Muscles become more tense
- Sweating
- Breeating rate increases.
