Osmosis is a biological process that takes place in cells and allows a substance to pass through the plasma membrane. Through osmosis, the plasma membrane, water can pass into and out of the cell through a gradient of solute concentration, that is, water passes from the place with the lowest concentration of solute to the place with the highest concentration, allowing thus the balance between the inter and extra cellular medium.

Leni [432]

If a person is not able to show stress in dangerous situations and lacks fear, there might be issues with an area of their brain known as the amygdala.

The amygdala is an almond-shaped structure which can be found in the medial temporal lobe of the brain, right in front of the hippocampus. It is a region of the brain which primarily deals with regulating our emotional processes like fear response but is also responsible for other strong emotions like aggression and pleasure. In case the amygdala gets damaged, it impairs the emotional memories of the person and also results in poor decision making.
