PATHOLOGY

Detailed explanation-1: -Your parasympathetic nervous system is a network of nerves that relaxes your body after periods of stress or danger. It also helps run life-sustaining processes, like digestion, during times when you feel safe and relaxed.

Detailed explanation-2: -Messages move from the brain through nerves and out to the body. A message enters the neuron through the dendrites and goes directly to the cell body. The message continues as an electrical impulse from one neuron to the next carrying the information to the brain.

Detailed explanation-3: -An overactive sympathetic nervous system can cause issues like muscle tension, jitters, insomnia, and more. It can also lead to hyper-vigilance, the tendency to detect danger, even in its absence. By contrast, excessive tiredness, depression, and an overactive gag reflex can signal parasympathetic dominance [3].
