Identification of calcium channel activation in 'fight or flight'
Researchers have further elucidated the calcium channels activated in the fight or flight response, the body's response to stress and acutely dangerous situations. Calcium plays a role in skeletal and cardiac muscle function, which are both affected by the stress response. Mediated by beta-adrenergic receptors, the broad calcium channel response allows quicker reflexes. Read more about the recent findings on the role of calcium channels in the fight or flight response.
