Step-by-step explanation:
Stress is an alarm response, common to all living beings, which begins after an injury, an aggression or a toxic or unpleasant, biological or psychological stimulation. By acting on the nervous system, cytokines stimulate neurons that control neurovegetative life and modify the release of neurotransmitters (catecholamines) that are mediators of the main clinical manifestations of stress. These same molecules can also act on lymphocytes and macrophages and modify the response of the immune system, the neurotransmitters produced by the neurovegetative system during the stress response represent a kind of interface in the relationships between the brain and the immune system.
