Self-verification also occurred reliably when neither the perceiver nor the target were highly certain of their beliefs. The only time in which the targetâs behavior reliably showed behavioral confirmation was when perceivers were highly certain of their beliefs, and targets were uncertain of their self-concepts. pp. 72
The response by your body is sometimes called the âfight or flightâ response. Adrenergic drugs stimulate the same nerves by either mimicking the action of the neurotransmitter norepinephrine or stimulating its release. They are used for many life-threatening conditions.
Adrenoceptors in the membranes of effector cells determine the physiological and metabolic effects of catecholamines. Key Concepts: Noradrenaline and adrenaline are catecholamines. Noradrenaline is the main neurotransmitter of the sympathetic nerves in the cardiovascular system. Adrenaline is the main hormone secreted by the adrenal medulla. The sympathetic noradrenergic system plays major roles in tonic and reflexive changes in cardiovascular tone. Adrenaline is a major determinant of responses to metabolic or global challenges to homeostasis.
