Adrenaline and noradrenaline hormones are catecholamines that are secreted from the adrenal medulla in response to the stimulation of the sympathetic nervous system. These hormones are released in response to neuronal impulses that originate from the hypothalamus and travel through the sympathetic nervous system to the adrenal medulla. The release of these hormones is a part of the body's fight or flight response, which is triggered by stress, fear, or excitement. The neuronal impulse causes the adrenal medulla to secrete adrenaline and noradrenaline into the bloodstream. Adrenaline and noradrenaline hormones then bind to specific receptors on the target organs and tissues, causing various physiological responses that help the body deal with stress.
