Sympathetic Nerves During Stress Condition:

Stress is a response of the body to a demanding situation. During stress conditions, the body activates its sympathetic nervous system to cope up with the situation.

What are Sympathetic Nerves?

The sympathetic nervous system is a part of the autonomic nervous system that helps in controlling the body's involuntary processes. It is responsible for the "fight or flight" response of the body during stressful situations.

What Happens During Stress Condition?

During a stress response, the hypothalamus in the brain releases a hormone called corticotrophin-releasing hormone (CRH). This hormone stimulates the pituitary gland to release another hormone called adrenocorticotropic hormone (ACTH). ACTH then stimulates the adrenal glands to release adrenaline and cortisol into the bloodstream.

Activation of Sympathetic Nerves:

Adrenaline and cortisol are the two hormones that activate the sympathetic nervous system during stress conditions. Adrenaline increases the heart rate, blood pressure, and respiration rate. It also causes the liver to release glucose into the bloodstream, which provides energy to the body.

Cortisol, on the other hand, increases the glucose levels in the bloodstream and helps in the metabolism of fats and proteins. It also suppresses the immune response and helps the body to cope up with stress.

Conclusion:

In conclusion, during stress conditions, the sympathetic nervous system is activated to help the body cope up with the situation. Adrenaline and cortisol are the two hormones that activate the sympathetic nervous system and help in the "fight or flight" response of the body.
