This response helps increase heart rate, elevate blood pressure, and sharpen focus to deal with the situation at hand.
Yes, glycogen synthesis is associated with the "fight or flight" reaction. During stressful situations, the body releases adrenaline, which activates signaling pathways that promote glycogen synthesis in the liver and muscles to provide energy for immediate use in response to the perceived threat.
The other name for the fight or flight response is the acute stress response.
The fight or flight response is a physiological reaction triggered by the sympathetic nervous system in response to a perceived threat or stressor. It prepares the body to either confront the threat or flee from it by increasing heart rate, dilating pupils, and releasing stress hormones like adrenaline. This response is essential for survival in dangerous situations.
Walter Cannon, a harvard physiologist, first investigated the fight or flight response in 1927.
Adrenaline is released by the adrenal glands, specifically the adrenal medulla. It is part of the body's stress response and helps prepare the body for "fight or flight" situations.
