The part of the human brain which controls the body's response to stress is the limbic system in the central nervous system and the sympathetic nervous system of the peripheral nervous system. The sympathetic nervous system has a hand in most biological responses related to stress, such as pupil dilation and secretion of adrenaline from the adrenal glands. The nervous system originates primarily from the spinal cord, but it has no specific nervous center. The limbic system regulates chemicals related to the activation of the sympathetic nervous system. The amygdala is often referred to the emotional center of the brain, producing responses such as rage or fear which prepare the body for a response to stimulus. The orbitofrontal complex is related to decision and action, and the hypothalamus controls arousal. All of these are related to stress response.
During this response, several things may occur. Pupils dilate, digestion ceases, and the bladder may relax. The circulatory system will up-regulate, increasing breathing rates, heart rate, blood flow, and blood pressure. Muscle blood vessels will dilate, preparing the body for quick reaction. Extended periods of arousal at high or low levels ultimately lead to exhaustion.

Is stress a nerve or tension?
Yes stress is a tension thing. It causes the person to take tension. It causes one to think negatively.
What other sorts of stress cause p lunula cells to emit light?
Aside from mechanical stress, other types of stress that can cause piezoluminescence in p lunula cells include electrical stress, thermal stress, and chemical stress. These stressors can trigger the release of energy, resulting in light emission from the crystals in the p lunula cells.
What are response cells?
Response cells are cells that respond to the immune system and react to diseases.
How do human cells react when an influenza cell attacks?
They react by producing interferons.
Where does stress come from?
Stress is a reaction rather than one individual thing. There are many causes of stress and how we react to them differs from person to person.
Can stress reduce red blood cells?
NO, but stress can cause rashes
What is the difference from old people cells and younge people cells?
The primary difference between old people's cells and young people's cells lies in their functionality and regenerative capacity. As people age, their cells undergo changes such as telomere shortening, increased oxidative stress, and a decline in the ability to repair DNA, which can lead to slower healing and less efficient cellular processes. Young cells typically exhibit better growth, division, and repair mechanisms, allowing for more effective responses to injury and stress. Additionally, older cells may accumulate more senescent cells, which can negatively impact surrounding tissues and overall health.
