MICROANATOMY

Detailed explanation-1: -Your sympathetic nervous system is the part of your nervous system that carries signals related to your “fight-or-flight” response. That makes it a key part of your response to stressful situations.

Detailed explanation-2: -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-3: -Your breathing usually does not require any thought, because it is controlled by the autonomic nervous system, also called the involuntary nervous system. The parasympathetic system slows your breathing rate. It causes your bronchial tubes to narrow and the pulmonary blood vessels to widen.

Detailed explanation-4: -This activates our sympathetic nervous system, accelerating our adrenal glands, cortisol levels and hormonal balance, which can affect our aging process. Breathing deeply, with a slow and steady inhalation to exhalation ratio, signals our parasympathetic nervous system to calm the body down.

Detailed explanation-5: -It is a decrease in sympathetic stimulation or tone that allows vasodilatation. During rest, sleep, or emotional tranquility, the parasympathetic nervous system predominates and controls the heart rate at a resting rate of 60-75 bpm.
